| CVE-2026-55599 | 1 Phpseclib | 1 Phpseclib | 2026-06-23 | 5.8 Medium |
| phpseclib is a PHP secure communications library. From 0.1.1 until 1.0.30, 2.0.55, and 3.0.54, when an application validates an untrusted X.509 certificate with phpseclib, X509::validateSignature() reads a URL out of that certificate's Authority Information Access (AIA) extension and connects to it. Attacker who supplies certificate fully controls host, port, and path of that connection. URL fetching is enabled by default, and no destination is blocked. An unauthenticated attacker can therefore make a validating server open connections to internal hosts and ports it should never reach, for example loopback 127.0.0.1, cloud metadata address 169.254.169.254, and internal-only services. This is a server-side request forgery (SSRF) caused by an insecure default. This vulnerability is fixed in 1.0.30, 2.0.55, and 3.0.54. | ||||
| CVE-2026-44167 | 1 Phpseclib | 1 Phpseclib | 2026-05-14 | 7.5 High |
| phpseclib is a PHP secure communications library. Prior to 1.0.29, 2.0.54, and 3.0.52, anyone loading untrusted ASN1 files (eg. X509 certificates, RSA PKCS8 private or public keys, etc). This is a bypass of CVE-2024-27355. This vulnerability is fixed in 1.0.29, 2.0.54, and 3.0.52. | ||||
| CVE-2026-32935 | 1 Phpseclib | 1 Phpseclib | 2026-05-08 | 5.9 Medium |
| phpseclib is a PHP secure communications library. Projects using versions 0.1.1 through 1.0.26, 2.0.0 through 2.0.51, and 3.0.0 through 3.0.49 are vulnerable to a to padding oracle timing attack when using AES in CBC mode. This issue has been fixed in versions 1.0.27, 2.0.52 and 3.0.50. | ||||
| CVE-2026-40194 | 1 Phpseclib | 1 Phpseclib | 2026-05-08 | 3.7 Low |
| phpseclib is a PHP secure communications library. Starting in 0.1.1 and prior to 3.0.51, 2.0.53, and 1.0.28, phpseclib\Net\SSH2::get_binary_packet() uses PHP's != operator to compare a received SSH packet HMAC against the locally computed HMAC. != on equal-length binary strings in PHP uses memcmp(), which short-circuits on the first differing byte. This is a real variable-time comparison (CWE-208), proven by scaling benchmarks. This vulnerability is fixed in 3.0.51, 2.0.53, and 1.0.28. | ||||
| CVE-2023-52892 | 1 Phpseclib | 1 Phpseclib | 2025-10-22 | 7.5 High |
| In phpseclib before 1.0.22, 2.x before 2.0.46, and 3.x before 3.0.33, some characters in Subject Alternative Name fields in TLS certificates are incorrectly allowed to have a special meaning in regular expressions (such as a + wildcard), leading to name confusion in X.509 certificate host verification. | ||||
| CVE-2024-27354 | 2 Debian, Phpseclib | 5 Debian Linux, 1x, 2x and 2 more | 2025-09-15 | 7.5 High |
| An issue was discovered in phpseclib 1.x before 1.0.23, 2.x before 2.0.47, and 3.x before 3.0.36. An attacker can construct a malformed certificate containing an extremely large prime to cause a denial of service (CPU consumption for an isPrime primality check). NOTE: this issue was introduced when attempting to fix CVE-2023-27560. | ||||
| CVE-2024-27355 | 2 Debian, Phpseclib | 2 Debian Linux, Phpseclib | 2025-09-15 | 7.5 High |
| An issue was discovered in phpseclib 1.x before 1.0.23, 2.x before 2.0.47, and 3.x before 3.0.36. When processing the ASN.1 object identifier of a certificate, a sub identifier may be provided that leads to a denial of service (CPU consumption for decodeOID). | ||||
| CVE-2023-27560 | 1 Phpseclib | 1 Phpseclib | 2025-03-06 | 7.5 High |
| Math/PrimeField.php in phpseclib 3.x before 3.0.19 has an infinite loop with composite primefields. | ||||
| CVE-2023-49316 | 1 Phpseclib | 1 Phpseclib | 2024-11-21 | 7.5 High |
| In Math/BinaryField.php in phpseclib 3 before 3.0.34, excessively large degrees can lead to a denial of service. | ||||
| CVE-2021-30130 | 2 Debian, Phpseclib | 2 Debian Linux, Phpseclib | 2024-11-21 | 7.5 High |
| phpseclib before 2.0.31 and 3.x before 3.0.7 mishandles RSA PKCS#1 v1.5 signature verification. | ||||
