CVE-2026-73253
Mongoose (embedded web server and network library) prior to version 7.22 is vulnerable to a TLS hostname verification bypass . The root cause is in mg_tls_verify_cert_san() and mg_tls_verify_cert_cn() (in src/tls_builtin.c), which call mg_match() — a function whose wildcard matching can cross DNS...
CVE-2026-73253 Mongoose: TLS Hostname Verification Bypass via Overly Permissive Wildcard Matching
Mongoose is an embedded web server and network library. Prior to version 7.22, an on-path network attacker with a wildcard certificate for a parent domain can impersonate deeper subdomains to a client using the built-in TLS stack. The mgtlsverifycertsan and mgtlsverifycertcn functions in...
CVE-2026-73251
Mongoose (embedded web server and network library) prior to 7.23 contains a critical TLS certificate verification flaw in src/tls_builtin.c. When a client is configured with a multi-certificate CA bundle, mg_tls_init() stores the bundle in tls->ca_bundle_der while tls->ca_der.len remains ze...
