The Advanced File Manager WordPress plugin before 5.4.13 does not perform capability checks in several of its file management AJAX actions, allowing users with any role to which an administrator has granted file-manager access (as low as Subscriber) to read arbitrary files on the server - including sensitive configuration files - and to overwrite existing non-PHP files, which can be leveraged to compromise administrator accounts and the whole site.
AnalysisAI
Missing capability checks in the Advanced File Manager WordPress plugin (before 5.4.13) allow any authenticated user holding administrator-delegated file-manager access - as low as Subscriber - to read arbitrary server files including wp-config.php and to overwrite existing non-PHP files, creating a direct path to full WordPress site compromise. The CVSS 8.5 score with a scope-changed vector reflects the severity of that impact, while AC:H captures the critical prerequisite: an administrator must explicitly grant file-manager access to low-privileged roles before exploitation is possible. …
