CVE-2026-56066Network attack vector

Unauthenticated file deletion via path traversal

Published Jun 26, 2026 · Updated Jun 26, 2026

Path traversal in ShortPixel Adaptive Images 3.11.4 and earlier allows remote attackers to delete arbitrary files without authentication. Patchstack and ShortPixel identify arbitrary file deletion but do not disclose the affected endpoint, code locus, or pathname operation. Internet-reachable WordPress sites running the plugin require no attacker credentials, and deletion of core site files can interrupt service.
