CVE ID :CVE-2026-42011
Published : May 7, 2026, 3:16 p.m. | 3 hours, 1 minute ago
Description :A flaw was found in gnutls. This vulnerability occurs because permitted name constraints were incorrectly ignored when previous Certificate Authorities (CAs) only had excluded name constraints. A remote attacker could exploit this to bypass critical name constraint checks during certificate validation. This bypass could lead to the acceptance of invalid certificates, potentially enabling spoofing or man-in-the-middle attacks against affected systems.
Severity: 7.4 | HIGH
