CVE-2025-13320Network attack vectorHinoki check available

Authenticated file deletion via array-valued avatar path

Published Dec 12, 2025 · Updated Dec 12, 2025

Arbitrary file deletion in WP User Manager 2.9.12 and earlier allows remote authenticated users to delete server files through profile updates. Profile update handling accepts an array-valued current_user_avatar input through PHP filter_input(), then passes its insufficiently validated path to file deletion. Subscriber-level access and custom avatars are required; the direct impact is file deletion, with site disruption and code execution depending on the targeted file.
