CVE-2026-13608

CVE-2026-13608 is a flaw in libcurl 's SASL negotiation for LDAP authentication where an incomplete handshake sequence is misinterpreted as a successful cryptographic verification. A Man-in-the-Middle attacker can inject a premature or shortcut response, bypassing complete peer validation. The vu...

CVE-2026-86219

Authen::SASL::Perl::DIGEST_MD5 versions before 2.2100 in Perl suffer from an unverified nonce in server_step. The server generates a fresh nonce in server_start but never compares it against the nonce returned by the client; instead, server_step derives the expected digest from the client's own p...
