CVE-2024-9425 is a stored cross-site scripting vulnerability in the sajjad67 Advanced Category and Custom Taxonomy Image WordPress plugin, affecting all versions up to and including 1.0.9. The issue occurs due to improper neutralization of input in the ad_tax_image shortcode, allowing authenticated users with contributor-level privileges or higher to inject arbitrary web scripts. These scripts execute in the context of any user who accesses the injected page, potentially leading to session hijacking or other script-based attacks. The vulnerability is classified under CWE-79 and has a CVSS 3.1 score of 6.4 (medium severity). No known exploits in the wild have been reported, and no patch or official fix has been documented at this time.

An attacker with contributor-level access or higher can exploit this vulnerability to inject and store malicious scripts that execute in the browsers of users viewing the affected pages. This can lead to unauthorized actions performed on behalf of users, data theft, or session hijacking. The vulnerability does not affect availability but impacts confidentiality and integrity to a limited extent. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access to trusted users only and consider disabling or removing the plugin if possible. Monitor for updates from the plugin author or WordPress security advisories to apply any forthcoming patches promptly.
