{"id":"CVE-2026-48168","summary":"PraisonAI: GitHub Actions Claude workflow command injection via unquoted PR branch name","details":"PraisonAI is a multi-agent teams system. In versions prior to 4.6.40, the bundled Claude GitHub Actions workflow is vulnerable to command injection because it embeds an attacker-controlled pull request branch name into a Bash run: block without quoting or validation. Additionally, the workflow allows any @claude comment to trigger the job regardless of whether the commenter is a trusted collaborator. An outside contributor can open a pull request from a fork whose branch name contains shell metacharacters and comment @claude, causing Bash to execute arbitrary shell code in the GitHub Actions runner. Because these commands run in a job holding a GitHub App token with write permissions, OIDC access, and gh/git access, the injection can be chained through $GITHUB_PATH to compromise later privileged steps, enabling repository writes, pull request and issue manipulation, or OIDC-token abuse. This issue has been fixed in version 4.6.40.","aliases":["GHSA-xp85-6wwf-r67c"],"modified":"2026-08-07T11:51:21.970843219Z","published":"2026-08-05T18:29:38.632Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48168.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-862"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48168.json"},{"type":"ADVISORY","url":"https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-xp85-6wwf-r67c"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-48168"},{"type":"FIX","url":"https://github.com/MervinPraison/PraisonAI/commit/179cab02dbec0c1e9b601507a659"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mervinpraison/praisonai","events":[{"introduced":"0"},{"fixed":"179cab02dbec0c1e9b601507a659"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"4.6.40"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-48168.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H"}]}
