{"id":"CVE-2025-61584","summary":"serverless-dns is vulnerable to Command Injection through pr.yml GitHub Action Workflow","details":"serverless-dns is a RethinkDNS resolver that deploys to Cloudflare Workers, Deno Deploy, Fastly, and Fly.io. Versions through abd including 0.1.30 have a vulnerability where the pr.yml GitHub Action interpolates in an unsafe manner untrusted input, specifically the github.event.pull_request.head.repo.clone_url and github.head_ref, to a command in the runner. Due to the action using the pull_request_target trigger it has permissive permissions by default. An unauthorized attacker can exploit this vulnerability to push arbitrary data to the repository. The subsequent impact on the end-user is executing the attackers' code when running serverless-dns. This is fixed in commit c5537dd, and expected to be released in 0.1.31.","aliases":["GHSA-9g7x-737f-5xpc"],"modified":"2026-07-15T01:48:50.806947215Z","published":"2025-09-30T00:12:23.873Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-77"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/61xxx/CVE-2025-61584.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/61xxx/CVE-2025-61584.json"},{"type":"ADVISORY","url":"https://github.com/serverless-dns/serverless-dns/security/advisories/GHSA-9g7x-737f-5xpc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-61584"},{"type":"FIX","url":"https://github.com/serverless-dns/serverless-dns/commit/c5537dd7f203c59f2b86d1e295c2371f3533946a"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/serverless-dns/serverless-dns","events":[{"introduced":"0"},{"fixed":"c5537dd7f203c59f2b86d1e295c2371f3533946a"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.1.31"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v0.1.30","v0.1.25","v0.1.24","v0.1.23","v0.1.22","v0.1.21","v0.1.20","v0.1.19","v0.1.18","v0.1.17","v0.1.16","v0.1.15","v0.1.14","v1.4.9","v0.1.13","v0.1.12","v0.1.11","v0.1.10","v0.1.9","v0.1.8","v0.1.7","v0.1.6","v0.1.5","v0.1.4","v0.1.3","v0.1.2","v0.1.1","show","list","v0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-61584.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:P"}]}
