CVE-2026-73251: CWE-295: Improper Certificate Validation in cesanta mongooseCVE-2026-73251 0 Mongoose is an embedded web server and network library. Prior to 7.23, a network attacker can impersonate a TLS server to a Mongoose client configured with a multi-certificate CA bundle. In src/tls_builtin.c, the mg_tls_init() function stores the bundle in tls->ca_bundle_der while tls->ca_der.len remains zero, and mg_tls_recv_cert() uses tls_bundle_find() to accept a Common Name match without calling mg_tls_verify_cert_signature(). A forged self-signed certificate can therefore satisfy hostname and CertificateVerify checks and enable interception, credential disclosure, traffic modification, and malicious responses. This issue is fixed in version 7.23. Join the discussion | CVE Database V5 | 08/20/2026, 17:34:50 UTC Added: 08/20/2026, 17:52:46 UTC |
