CVE-2026-64943Hinoki check available

Credential disclosure via plaintext API-key logging

Published Oct 19, 2026 · Updated Oct 19, 2026

Credential disclosure in Apache Answer 2.0.2 and earlier allows attackers to recover API keys from authentication logs. Authentication request logging writes full API keys to application logs on every authenticated request instead of withholding the credentials. Exploitation requires log-read access and exposes active bearer credentials for replay with the access granted to those keys.
