CVE-2026-2498 is a stored cross-site scripting vulnerability in the WP Social Meta plugin for WordPress, affecting all versions up to 1.0.1. The vulnerability arises from improper neutralization of input during web page generation (CWE-79), allowing authenticated administrators to inject arbitrary scripts via admin settings. These scripts execute when users visit the injected pages. The vulnerability specifically impacts multi-site installations or installations with unfiltered_html disabled. The CVSS 3.1 base score is 4.4, reflecting a medium severity with network attack vector, high attack complexity, and requiring high privileges without user interaction.

An attacker with administrator-level privileges can exploit this vulnerability to inject malicious scripts that execute in the context of other users viewing the affected pages. This can lead to limited confidentiality and integrity impacts, such as session hijacking or unauthorized actions performed on behalf of users. The vulnerability does not affect availability. The impact is constrained by the requirement for high privileges and the specific installation configurations (multi-site or unfiltered_html disabled). No known exploits in the wild have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, administrators should limit access to trusted users only and consider disabling or removing the WP Social Meta plugin in multi-site environments or where unfiltered_html is disabled. Monitoring for plugin updates from bulktheme is recommended to apply any forthcoming patches promptly.
