CVE-2026-9282Public exploitNetwork attack vector

Unauthenticated file read via unchecked minify paths

Published Jul 11, 2026 · Updated Jul 11, 2026

Path traversal in BoldGrid W3 Total Cache 2.9.4 and earlier allows remote attackers to read arbitrary server files through minify requests. In manual minify mode, setupSources accepts attacker-controlled f_array[] paths when a manual-format filename produces an empty hash, leaving those entries unchanged and permitting traversal. The affected site must use manual minify mode; successful reads are limited to files accessible to the WordPress/PHP process, including sensitive configuration data.
