CVE-2026-67598Public exploit

API key theft via disabled TLS validation

Published Aug 3, 2026 · Updated Aug 3, 2026

Improper certificate validation in emlog Pro through 2.6.23 allows man-in-the-middle attackers to intercept outbound AI requests. Four request paths in include/service/ai.php disable CURLOPT_SSL_VERIFYPEER and CURLOPT_SSL_VERIFYHOST, causing cURL to accept arbitrary certificates. Exploitation requires a network interception position and configured AI credentials, exposing Bearer API keys and permitting injected AI responses.
