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."}], "lastModified": "2026-05-21T19:25:30.010", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:owasp:owasp_blt:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "C9D716C3-AC30-4AD0-8BA8-AEBEF29A1980", "versionEndIncluding": "2.1"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
