CVE-2026-58062
|
| Summary | Stapled OCSP response accepted without binding to the checked certificate Affects Bouncy Castle for Java LTS before 2.73.12. In the stapled OCSP path, ProvOcspRevocationChecker verifies the response signature and then searches for a SingleResponse matching the certificate's serial and issuer hashes, but returns normally when none matches, so the certificate is treated as unrevoked with no CRL fallback. The network-fetch path enforces this binding; the stapled path does not. A server holding a revoked certificate can staple any validly signed response from the same CA and pass revocation checking. |
