CVE-2025-12457 is a stored cross-site scripting vulnerability in the ideastocode Enable SVG, WebP, and ICO Upload WordPress plugin, affecting all versions up to 1.1.2. The flaw allows authenticated users with Author-level privileges or higher to upload crafted SVG files containing malicious scripts. Due to inadequate input sanitization and output escaping, these scripts execute in the context of users viewing the SVG files, potentially leading to session hijacking or other script-based attacks. The vulnerability has a CVSS 3.1 base score of 6.4 (medium severity), with network attack vector, low attack complexity, and no user interaction required beyond authentication.

An attacker with Author-level or higher access can exploit this vulnerability to inject and store malicious scripts via SVG file uploads. These scripts execute when other users access the SVG files, potentially compromising user sessions or performing unauthorized actions within the context of the affected WordPress site. The impact is limited to confidentiality and integrity loss with no direct availability impact. There are no known active exploits reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Author-level user permissions to trusted users only and consider disabling SVG uploads if possible. Monitor for updates from the plugin vendor and apply patches promptly once available.
