Deeper analysis
The FlatPM WordPress plugin before version 3.0.13 contains a reflected cross-site scripting vulnerability. The plugin fails to sanitize and escape certain parameters before echoing them back into web pages, allowing script injection that affects the plugin component running on WordPress sites.
An authenticated attacker with low privileges can supply a crafted URL or request containing malicious JavaScript. When a high-privilege user such as an administrator follows the link, the script executes in the victim's browser context with the site's origin, enabling limited impacts on confidentiality and integrity as reflected by the CVSS vector.
Advisories published by WPScan identify the flaw and direct users to upgrade the FlatPM plugin to version 3.0.13 or later to eliminate the unsanitized parameter handling.
The associated EPSS score rose materially from lower values to a peak of 0.3014 on 2025-12-11 before receding to the current 0.0485, indicating a period of increased exploitation interest after disclosure.
