{"cve":"CVE-2025-24976","nvd":{"published":"2025-02-11T16:15:52.163","modified":"2026-06-17T08:59:54.903","status":"Deferred","description":"Distribution is a toolkit to pack, ship, store, and deliver container content. Systems running registry versions 3.0.0-beta.1 through 3.0.0-rc.2 with token authentication enabled may be vulnerable to an issue in which token authentication allows an attacker to inject an untrusted signing key in a JSON web token (JWT). The issue lies in how the JSON web key (JWK) verification is performed. When a JWT contains a JWK header without a certificate chain, the code only checks if the KeyID (`kid`) matches one of the trusted keys, but doesn't verify that the actual key material matches. A fix for the issue is available at commit 5ea9aa028db65ca5665f6af2c20ecf9dc34e5fcd and expected to be a part of version 3.0.0-rc.3. There is no way to work around this issue without patching if the system requires token authentication.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U","score":6.6},"cvss_v3":null,"cwes":["CWE-639"],"references":["https://github.com/distribution/distribution/commit/f4a500caf68169dccb0b54cb90523e68ee1ac2be","https://github.com/distribution/distribution/security/advisories/GHSA-phw4-mc57-4hwc"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:59:18.731010617+00:00"},"epss":{"cve":"CVE-2025-24976","score":0.00353,"percentile":0.29061,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GO-2025-3460","url":"https://osv.dev/vulnerability/GO-2025-3460","summary":"Distribution's token authentication allows attacker to inject an untrusted signing key in a JWT in github.com/distribution/distribution","modified":"2026-02-04T02:22:56.136310Z","packages":[{"ecosystem":"Go","name":"github.com/distribution/distribution","purl":"pkg:golang/github.com/distribution/distribution","ranges":["all versions"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
