- Web page: https://patchblox.com/security/cve/CVE-2026-42011
- Priority: High
- CVSS: 8.2 (Moderate)
- EPSS: 0.0048
- CISA KEV: not listed
- Exploited (vendor report): no
- Publicly disclosed: no
- Published: Apr 29, 2026
- Weakness: Improper Certificate Validation
- Vendor advisory: https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-42011

## 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.
