CVE-2026-115881
Published:October 12, 2026
Updated:October 28, 2026
GoAhead's OpenSSL TLS backend loads the configured certificate revocation list (ME_GOAHEAD_SSL_REVOKE) in sslOpen() (src/openssl.c) but never sets X509_V_FLAG_CRL_CHECK, so OpenSSL never consults it. Under mutual TLS, a client whose certificate has been revoked still completes the handshake and is authenticated. mbedtls builds are not affected. Affects 3.4.5 through 6.1.0; fixed in 6.1.1.
