The workflow pr.yml uses the pull_request_target trigger with the repository's default write permissions and passes them down to check-types.yml. check-types.yml then performs a 'dangerous' checkout of the attacker-submitted pull request code (via the dangerous-git-checkout action) and subsequently executes it (through yarn install and package.json scripts). An attacker can open a pull request whose code runs arbitrary commands with the repository's write-scoped GITHUB_TOKEN, allowing them to push commits, merge or mutate pull requests, add or delete comments, and delete or force-push branches, thereby compromising the repository. The main branch is affected; no patched version is available."}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "Improper Neutralization of Special Elements used in a Command ('Command Injection')", "cweId": "CWE-77", "type": "CWE"}]}], "affected": [{"vendor": "calcom", "product": "cal.diy", "defaultStatus": "affected"}], "metrics": [{"format": "CVSS", "cvssV4_0": {"version": "4.0", "vectorString": "CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:H/VA:H/SC:L/SI:H/SA:H", "attackVector": "NETWORK", "attackComplexity": "LOW", "attackRequirements": "NONE", "privilegesRequired": "LOW", "userInteraction": "NONE", "vulnConfidentialityImpact": "LOW", "vulnIntegrityImpact": "HIGH", "vulnAvailabilityImpact": "HIGH", "subConfidentialityImpact": "LOW", "subIntegrityImpact": "HIGH", "subAvailabilityImpact": "HIGH", "baseScore": 8.5, "baseSeverity": "HIGH"}}, {"format": "CVSS", "cvssV3_1": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:H/A:H", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "CHANGED", "confidentialityImpact": "LOW", "integrityImpact": "HIGH", "availabilityImpact": "HIGH", "baseScore": 9.9, "baseSeverity": "CRITICAL"}}], "references": [{"url": "https://github.com/calcom/cal.diy/security/advisories/GHSA-p3f6-52gv-cj7m", "name": "GitHub Security Advisory (GHSA-p3f6-52gv-cj7m)", "tags": ["vendor-advisory"]}, {"url": "https://github.com/calcom/cal.diy/commit/9aa60fae41a6b6b101c86bf430754b439f440871", "name": "https://github.com/calcom/cal.diy/commit/9aa60fae41a6b6b101c86bf430754b439f440871", "tags": ["patch"]}, {"name": "VulnCheck Advisory: cal.com Repository Takeover via pull_request_target Workflow", "tags": ["third-party-advisory"], "url": "https://www.vulncheck.com/advisories/cal-com-repository-takeover-via-pull-request-target-workflow"}], "credits": [{"lang": "en", "value": "jsoref", "type": "reporter"}], "x_generator": {"engine": "vulncheck-endgame"}}}}
