With `UnknownStatusPolicy::Deny` (the default) this would lead to incorrect but safe `Error::UnknownRevocationStatus`. With `UnknownStatusPolicy::Allow` this would lead to inappropriate acceptance of revoked certificates.\n\nThis vulnerability is thought to be of limited impact. This is because both the certificate and CRL are signed -- an attacker would need to compromise a trusted issuing authority to trigger this bug.  An attacker with such capabilities could likely bypass revocation checking through other more impactful means (such as publishing a valid, empty CRL.)\n\nMore likely, this bug would be latent in normal use, and an attacker could leverage faulty revocation checking to continue using a revoked credential.","id":"GHSA-pwjx-qhcg-rvj4","modified":"2026-09-19T03:55:49.529651638Z","published":"2026-03-20T21:51:17Z","references":[{"type":"WEB","url":"https://github.com/rustls/webpki/security/advisories/GHSA-pwjx-qhcg-rvj4"},{"type":"PACKAGE","url":"https://github.com/rustls/webpki"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2026-0049.html"}],"schema_version":"1.9.0","severity":[{"score":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:H/A:N","type":"CVSS_V3"}],"summary":"webpki: CRLs not considered authoritative by Distribution Point due to faulty matching logic"}
