The Malcure Malware Shield WordPress plugin suffers from a missing authorization check (CWE-862) in the wpmr_inspect_file() function, enabling authenticated users with low privileges (subscriber-level and above) to read arbitrary server files. This vulnerability affects all versions up to 16.8 and can lead to unauthorized disclosure of sensitive data. The CVSS 3.1 score of 6.5 reflects a medium severity with network attack vector, low attack complexity, and no user interaction required. No official patch or vendor advisory is currently available, and no known exploits have been reported.

An attacker with subscriber-level access or higher can exploit this vulnerability to read arbitrary files on the server, potentially exposing sensitive information such as configuration files, credentials, or other private data. There is no impact on integrity or availability reported. The vulnerability does not require user interaction and can be exploited remotely over the network.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict subscriber-level access to trusted users only and monitor for suspicious activity related to file access. Avoid exposing sensitive files in locations accessible to the plugin. Follow vendor channels for updates and apply patches promptly once available.
