CVE-2026-95210
validatedZero produced an exploit or a check.GHSA-9mfx-g534-q3pc ↗EUVD-2026-95139 ↗
description
GnuTLS 3.8.13 may accept certificates containing invalid extensions during certificate validation. An attacker able to present such a certificate could cause an affected application to treat it as acceptable.
mitigation
Restrict affected applications to trusted endpoints and add independent certificate-policy checks where feasible. Monitor GnuTLS release guidance and upgrade when a corrected version is identified.
outcome
Contextual check: a technique exists and was validated, but no deterministic check could cover this one.
source signals
Public signals that triggered or updated the pipeline. These are inputs for the deltas above.
