Vulnerability identifier: #VU119236

CSH Severity: Low

CVSS v4 BT: 0.5 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2025-61727

CWE-ID: CWE-295

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists in crypto/x509 due to incorrect handling of wildcard SANs in the leaf certificate when processing excluded constraint in a certificate chain. A remote attacker can create a specially crafted certificate and bypass implemented domain restrictions and perform MitM or phishing attacks.
