CVE-2026-40321 1 Dnnsoftware 1 Dnn Platform 2026-04-20 8.1 High
DNN (formerly DotNetNuke) is an open-source web content management platform (CMS) in the Microsoft ecosystem. Prior to version 10.2.2, a user could upload a specially crafted SVG file that could include scripts that can target both authenticated and unauthenticated DNN users. The impact is increased if the scripts are run by a power user. Version 10.2.2 patches the issue.
CVE-2026-40324 1 Chillicream 1 Graphql-platform 2026-04-20 9.1 Critical
Hot Chocolate is an open-source GraphQL server. Prior to versions 12.22.7, 13.9.16, 14.3.1, and 15.1.14, Hot Chocolate's recursive descent parser `Utf8GraphQLParser` has no recursion depth limit. A crafted GraphQL document with deeply nested selection sets, object values, list values, or list types can trigger a `StackOverflowException` on payloads as small as 40 KB. Because `StackOverflowException` is uncatchable in .NET (since .NET 2.0), the entire worker process is terminated immediately. All in-flight HTTP requests, background `IHostedService` tasks, and open WebSocket subscriptions on that worker are dropped. The orchestrator (Kubernetes, IIS, etc.) must restart the process. This occurs before any validation rules run — `MaxExecutionDepth`, complexity analyzers, persisted query allow-lists, and custom `IDocumentValidatorRule` implementations cannot intercept the crash because `Utf8GraphQLParser.Parse` is invoked before validation. The `MaxAllowedFields=2048` limit does not help because the crashing payloads contain very few fields. The fix in versions 12.22.7, 13.9.16, 14.3.1, and 15.1.14 adds a `MaxAllowedRecursionDepth` option to `ParserOptions` with a safe default, and enforces it across all recursive parser methods (`ParseSelectionSet`, `ParseValueLiteral`, `ParseObject`, `ParseList`, `ParseTypeReference`, etc.). When the limit is exceeded, a catchable `SyntaxException` is thrown instead of overflowing the stack. There is no application-level workaround. `StackOverflowException` cannot be caught in .NET. The only mitigation is to upgrade to a patched version. Operators can reduce (but not eliminate) risk by limiting HTTP request body size at the reverse proxy or load balancer layer, though the smallest crashing payload (40 KB) is well below most default body size limits and is highly compressible (~few hundred bytes via gzip).
CVE-2026-28214 1 Firebirdsql 1 Firebird 2026-04-20 N/A
Firebird is an open-source relational database management system. In versions prior to 5.0.4, 4.0.7 and 3.0.14, the ClumpletReader::getClumpletSize() function can overflow the totalLength value when parsing a Wide type clumplet, causing an infinite loop. An authenticated user with INSERT privileges on any table can exploit this via a crafted Batch Parameter Block to cause a denial of service against the server. This issue has been fixed in versions 5.0.4, 4.0.7 and 3.0.14.
CVE-2026-34232 1 Firebirdsql 1 Firebird 2026-04-20 7.5 High
Firebird is an open-source relational database management system. In versions prior to 5.0.4, 4.0.7 and 3.0.14, the xdr_status_vector() function does not handle the isc_arg_cstring type when decoding an op_response packet, causing a server crash when one is encountered in the status vector. An unauthenticated attacker can exploit this by sending a crafted op_response packet to the server. This issue has been fixed in versions 5.0.4, 4.0.7 and 3.0.14.
CVE-2026-40196 1 Sysadminsmedia 1 Homebox 2026-04-20 8.1 High
HomeBox is a home inventory and organization system. Versions prior to 0.25.0 contain a vulnerability where the defaultGroup ID remained permanently assigned to a user after being invited to a group, even after their access to that group was revoked. While the web interface correctly enforced the access revocation and prevented the user from viewing or modifying the group's contents, the API did not. Because the original group ID persisted as the user's defaultGroup, and this value was not properly validated when the X-Tenant header was omitted, the user could still perform full CRUD operations on the group's collections through the API, bypassing the intended access controls. This issue has been fixed in version 0.25.0.
CVE-2026-40299 1 Amannn 1 Next-intl 2026-04-20 4.3 Medium
next-intl provides internationalization for Next.js. Applications using the `next-intl` middleware prior to version 4.9.1with `localePrefix: 'as-needed'` could construct URLs where path handling and the WHATWG URL parser resolved a relative redirect target to another host (e.g. scheme-relative `//` or control characters stripped by the URL parser), so the middleware could redirect the browser off-site while the user still started from a trusted app URL. The problem has been patchedin `next-intl@4.9.1`.
CVE-2026-40301 1 Rhukster 1 Dom-sanitizer 2026-04-20 4.7 Medium
DOMSanitizer is a DOM/SVG/MathML Sanitizer for PHP 7.3+. Prior to version 1.0.10, DOMSanitizer::sanitize() allows <style> elements in SVG content but never inspects their text content. CSS url() references and @import rules pass through unfiltered, causing the browser to issue HTTP requests to attacker-controlled hosts when the sanitized SVG is rendered. Version 1.0.10 fixes the issue.
CVE-2026-40302 1 Openziti 1 Zrok 2026-04-20 6.1 Medium
zrok is software for sharing web services, files, and network resources. Prior to version 2.0.1, the proxyUi template engine uses Go's text/template (which performs no HTML escaping) instead of html/template. The GitHub OAuth callback handlers in both publicProxy and dynamicProxy embed the attacker-controlled refreshInterval query parameter verbatim into an error message when time.ParseDuration fails, and render that error unescaped into HTML. An attacker can deliver a crafted login URL to a victim; after the victim completes the GitHub OAuth flow, the callback page executes arbitrary JavaScript in the OAuth server's origin. Version 2.0.1 patches the issue.
CVE-2026-40304 1 Openziti 1 Zrok 2026-04-20 5.3 Medium
zrok is software for sharing web services, files, and network resources. Prior to version 2.0.1, the unaccess handler (controller/unaccess.go) contains a logical error in its ownership guard: when a frontend record has environment_id = NULL (the marker for admin-created global frontends), the condition short-circuits to false and allows the deletion to proceed without any ownership verification. A non-admin user who knows a global frontend token can call DELETE /api/v2/unaccess with any of their own environment IDs and permanently delete the global frontend, taking down all public shares routed through it. Version 2.0.1 patches the issue.
CVE-2026-40323 1 Succinctlabs 1 Sp1 2026-04-20 N/A
SP1 is a zero‑knowledge virtual machine that proves the correct execution of programs compiled for the RISC-V architecture. In versions 6.0.0 through 6.0.2, a soundness vulnerability in the SP1 V6 recursive shard verifier allows a malicious prover to construct a recursive proof from a shard proof that the native verifier would reject. Version 6.1.0 fixes the issue.
CVE-2026-40476 1 Webonyx 1 Graphql-php 2026-04-20 N/A
graphql-go is a Go implementation of GraphQL. In versions 15.31.4 and below, the OverlappingFieldsCanBeMerged validation rule performs O(n²) pairwise comparisons of fields sharing the same response name. An attacker can send a query with thousands of repeated identical fields, causing excessive CPU usage during validation before execution begins. This is not mitigated by existing QueryDepth or QueryComplexity rules. This issue has been fixed in version 15.31.5.
CVE-2026-40486 1 Kimai 1 Kimai 2026-04-20 4.3 Medium
Kimai is an open-source time tracking application. In versions 2.52.0 and below, the User Preferences API endpoint (PATCH /api/users/{id}/preferences) applies submitted preference values without checking the isEnabled() flag on preference objects. Although the hourly_rate and internal_rate fields are correctly marked as disabled for users lacking the hourly-rate role permission, the API ignores this restriction and saves the values directly. Any authenticated user can modify their own billing rates through this endpoint, resulting in unauthorized financial tampering affecting invoices and timesheet calculations. This issue has been fixed in version 2.53.0.
CVE-2026-40572 1 Minecanton209 1 Novumos 2026-04-20 9 Critical
NovumOS is a custom 32-bit operating system written in Zig and x86 Assembly. In versions prior to 0.24, Syscall 15 (MemoryMapRange) allows Ring 3 user-mode processes to map arbitrary virtual address ranges into their address space without validating against forbidden regions, including critical kernel structures such as the IDT, GDT, TSS, and page tables. A local attacker can exploit this to modify kernel interrupt handlers, resulting in privilege escalation from user mode to kernel context. This issue has been fixed in version 0.24.
CVE-2026-24467 2026-04-20 9.1 Critical
OpenAEV is an open source platform allowing organizations to plan, schedule and conduct cyber adversary simulation campaign and tests. Starting in version 1.0.0 and prior to version 2.0.13, OpenAEV's password reset implementation contains multiple security weaknesses that together allow reliable account takeover. The primary issue is that password reset tokens do not expire. Once a token is generated, it remains valid indefinitely, even if significant time has passed or if newer tokens are issued for the same account. This allows an attacker to accumulate valid password reset tokens over time and reuse them at any point in the future to reset a victim’s password. A secondary weakness is that password reset tokens are only 8 digits long. While an 8-digit numeric token provides 100,000,000 possible combinations (which is secure enough), the ability to generate large numbers of valid tokens drastically reduces the required number of attempts to guess a valid password reset token. For example, if an attacker generates 2,000 valid tokens, the brute-force effort is reduced to approximately 50,000 attempts, which is a trivially achievable number of requests for an automated attack. (100 requests per second can mathematically find a valid password reset token in 500 seconds.) By combining these flaws, an attacker can mass-generate valid password reset tokens and then brute-force them efficiently until a match is found, allowing the attacker to reset the victim’s password to a value of their choosing. The original password is not required, and the attack can be performed entirely without authentication. This vulnerability enables full account takeover that leads to platform compromise. An unauthenticated remote attacker can reset the password of any registered user account and gain complete access without authentication. Because user email addresses are exposed to other users by design, a single guessed or observed email address is sufficient to compromise even administrator accounts with non-guessable email addresses. This design flaw results in a reliable and scalable account takeover vulnerability that affects any registered user account in the system. Note: The vulnerability does not require OpenAEV to have the email service configured. The exploit does not depend on the target email address to be a real email address. It just needs to be registered to OpenAEV. Successful exploitation allows an unauthenticated remote attacker to access sensitive data (such as the Findings section of a simulation), modify payloads executed by deployed agents to compromise all hosts where agents are installed (therefore the Scope is changed). Users should upgrade to version 2.0.13 to receive a fix.
CVE-2026-35465 1 Freedomofpress 1 Securedrop-client 2026-04-20 7.5 High
SecureDrop Client is a desktop app for journalists to securely communicate with sources and handle submissions on the SecureDrop Workstation. In versions 0.17.4 and below, a compromised SecureDrop Server can achieve code execution on the Client's virtual machine (sd-app) by exploiting improper filename validation in gzip archive extraction, which permits absolute paths and enables overwriting critical files like the SQLite database. Exploitation requires prior compromise of the dedicated SecureDrop Server, which itself is hardened and only accessible via Tor hidden services. Despite the high attack complexity, the vulnerability is rated High severity due to its significant impact on confidentiality, integrity, and availability of decrypted source submissions. This issue is similar to CVE-2025-24888 but occurs through a different code path, and a more robust fix has been implemented in the replacement SecureDrop Inbox codebase. The issue has been fixed in version 0.17.5.
CVE-2026-35512 1 Neutrinolabs 1 Xrdp 2026-04-20 N/A
xrdp is an open source RDP server. Versions through 0.10.5 have a heap-based buffer overflow in the EGFX (graphics dynamic virtual channel) implementation due to insufficient validation of client-controlled size parameters, allowing an out-of-bounds write via crafted PDUs. Pre-authentication exploitation can crash the process, while post-authentication exploitation may achieve remote code execution. This issue has been fixed in version 0.10.6. If users are unable to immediately update, they should run xrdp as a non-privileged user (default since 0.10.2) to limit the impact of successful exploitation.
CVE-2026-40347 1 Kludex 1 Python-multipart 2026-04-20 5.3 Medium
Python-Multipart is a streaming multipart parser for Python. Versions prior to 0.0.26 have a denial of service vulnerability when parsing crafted `multipart/form-data` requests with large preamble or epilogue sections. Upgrade to version 0.0.26 or later, which skips ahead to the next boundary candidate when processing leading CR/LF data and immediately discards epilogue data after the closing boundary.
CVE-2026-40487 1 Gitroomhq 1 Postiz-app 2026-04-20 8.9 High
Postiz is an AI social media scheduling tool. Prior to version 2.21.6, a file upload validation bypass allows any authenticated user to upload arbitrary HTML, SVG, or other executable file types to the server by spoofing the `Content-Type` header. The uploaded files are then served by nginx with a Content-Type derived from their original extension (`text/html`, `image/svg+xml`), enabling Stored Cross-Site Scripting (XSS) in the context of the application's origin. This can lead to session riding, account takeover, and full compromise of other users' accounts. Version 2.21.6 contains a fix.
CVE-2026-40317 1 Minecanton209 1 Novumos 2026-04-20 9.4 Critical
NovumOS is a custom 32-bit operating system written in Zig and x86 Assembly. In versions prior to 0.24, Syscall 12 (JumpToUser) accepts an arbitrary entry point address from user-space registers without validation, allowing any Ring 3 user-mode process to jump to kernel addresses and execute arbitrary code in Ring 0 context, resulting in local privilege escalation. This issue has been fixed in version 0.24. If developers are unable to immediately update, they should restrict syscall access by running the system in single-user mode without Ring 3, and disable user-mode processes by only running kernel shell with no user processes. This issue has been fixed in version 0.24.
CVE-2026-41245 1 Junrar 1 Junrar 2026-04-20 5.9 Medium
Junrar is an open source java RAR archive library. Prior to version 7.5.10, a path traversal vulnerability in `LocalFolderExtractor` allows an attacker to write arbitrary files with attacker-controlled content into sibling directories when a crafted RAR archive is extracted. Version 7.5.10 fixes the issue.
