• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.5% probability of exploitation in the next 30 days
• Public exploit or detection template: none known

Description

The Code Explorer plugin for WordPress is vulnerable to arbitrary external file reading in all versions up to, and including, 1.4.5. This is due to the fact that the plugin does not restrict accessing files to those outside of the WordPress instance, though the intention of the plugin is to only access WordPress related files. This makes it possible for authenticated attackers, with administrator-level access, to read files outside of the WordPress instance.
