{"id":"CVE-2026-40316","state":"PUBLISHED","title":"OWASP BLT has RCE in Github Actions via untrusted Django model execution in workflow","description":"OWASP BLT is a QA testing and vulnerability disclosure platform that encompasses websites, apps, git repositories, and more. Versions prior to 2.1.1 contain an RCE vulnerability in the .github/workflows/regenerate-migrations.yml workflow. The workflow uses the pull_request_target trigger to run with full GITHUB_TOKEN write permissions, copies attacker-controlled files from untrusted pull requests into the trusted runner workspace via git show, and then executes python manage.py makemigrations, which imports Django model modules including attacker-controlled website/models.py at runtime. Any module-level Python code in the attacker's models.py is executed during import, enabling arbitrary code execution in the privileged CI environment with access to GITHUB_TOKEN and repository secrets. The attack is triggerable by any external contributor who can open a pull request, provided a maintainer applies the regenerate-migrations label, potentially leading to secret exfiltration, repository compromise, and supply chain attacks. A patch for this issue is expected to be released in version 2.1.1.","publishedAt":"2026-04-15T22:49:18.636Z","updatedAt":"2026-04-16T14:18:12.374Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["OWASP-BLT BLT"],"affected":[{"vendor":"OWASP-BLT","product":"BLT","versions":[{"version":"<= 2.1","status":"affected"}]}],"references":["https://github.com/OWASP-BLT/BLT/security/advisories/GHSA-wxm3-64fx-cmx9"],"weaknesses":["CWE-94","CWE-95"],"ingestedAt":"2026-10-29T20:11:57.932Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/40xxx/CVE-2026-40316.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-40316","state":"PUBLISHED","datePublished":"2026-04-15T22:49:18.636Z","dateUpdated":"2026-04-16T14:18:12.374Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-04-10T21:41:54.505Z"},"containers":{"cna":{"title":"OWASP BLT has RCE in Github Actions via untrusted Django model execution in workflow","descriptions":[{"lang":"en","value":"OWASP BLT is a QA testing and vulnerability disclosure platform that encompasses websites, apps, git repositories, and more.
