python: python: Certificate verification bypass via missing server_hostname validation in SSLContext.wrap_bio()

A flaw was found in Python. When establishing secure connections using the SSLContext.wrapbio function with hostname checking enabled, the module fails to validate that a target server hostname is supplied. Because of this missing check, certificate hostname verification is silently skipped rathe...

CVE-2026-107660 FFmpeg before 8.1.3 and 9.x before 9.0.2 mbedTLS Hostname Verification Bypass for IP Hosts

FFmpeg before 8.1.3 and 9.x before 9.0.2 contains an improper certificate validation vulnerability in tlsopen of libavformat/tlsmbedtls.c, which skips hostname checks for IP-address hosts. Network attackers can intercept https, rtmps, or tls connections to IP-literal URLs with any trusted CA-issu...
