CVE-2025-52023Network attack vector

Information disclosure via verbose PHP errors

Published Jan 23, 2026 · Updated Jan 23, 2026

Information disclosure in Aptsys gemscms backend through 2025-05-28 allows remote attackers to read server internals via malformed API requests. Public API endpoints return unhandled PHP exception output, including internal file paths, code snippets, and stack traces, instead of sanitized errors. No authentication or user interaction is required, and the disclosed internals support reconnaissance rather than direct data modification or service interruption.
