{"id":"CVE-2024-58354","summary":"cal.com Repository Takeover via pull_request_target Workflow","details":"cal.com (calcom repository, later renamed cal.diy) is affected by a repository takeover vulnerability in its GitHub Actions workflows. 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.","aliases":["GHSA-p3f6-52gv-cj7m"],"modified":"2026-07-27T03:56:24.511332771Z","published":"2026-07-23T21:16:43.545Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/58xxx/CVE-2024-58354.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-77"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/58xxx/CVE-2024-58354.json"},{"type":"ADVISORY","url":"https://github.com/calcom/cal.diy/security/advisories/GHSA-p3f6-52gv-cj7m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-58354"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/cal-com-repository-takeover-via-pull-request-target-workflow"},{"type":"FIX","url":"https://github.com/calcom/cal.diy/commit/9aa60fae41a6b6b101c86bf430754b439f440871"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/calcom/cal.diy","events":[{"introduced":"0"},{"fixed":"9aa60fae41a6b6b101c86bf430754b439f440871"}],"database_specific":{"source":"REFERENCES"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-58354.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"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"}]}
