CVE-2024-11098 is a stored cross-site scripting vulnerability in the mr2p SVG Block WordPress plugin. It affects all versions up to 1.1.24 and allows authenticated administrators to upload malicious SVG files via the REST API. Due to improper input sanitization and output escaping, these SVG files can contain scripts that execute in the context of users viewing the SVG, potentially leading to script injection attacks. The vulnerability is rated medium severity with a CVSS 3.1 base score of 5.5. No patch or remediation details have been provided by the vendor, and the plugin is not a cloud service, so remediation depends on plugin updates.

An attacker with Administrator-level access can inject malicious scripts into SVG files uploaded via the REST API. These scripts execute in the context of users who view the SVG, potentially leading to unauthorized actions or data exposure limited to the privileges of the affected users. The vulnerability does not impact availability and requires high privileges to exploit. There are no reports of active exploitation in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Administrator-level access to trusted users only and consider disabling SVG uploads via the REST API if possible. Monitor for plugin updates from mr2p and apply them promptly once available.
