GHSA-6V2V-JGG9-H79W

Vulnerability from github – Published: 2026-04-10 00:30 – Updated: 2026-04-29 15:30
VLAI
Details

A 1-byte stack buffer over-read was identified in the MatchDomainName function (src/internal.c) during wildcard hostname validation when the LEFT_MOST_WILDCARD_ONLY flag is active. If a wildcard * exhausts the entire hostname string, the function reads one byte past the buffer without a bounds check, which could cause a crash.
