CVE-2024-8103 is a stored cross-site scripting vulnerability in the WP Category Dropdown plugin by GCS Design for WordPress. It occurs due to improper neutralization of input in the 'align' parameter, allowing authenticated users with Contributor or higher privileges to inject arbitrary web scripts. These scripts execute when any user accesses the compromised page, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all versions up to 1.8. The CVSS score of 6.4 reflects a medium risk with network attack vector, low attack complexity, and privileges required at the contributor level.

An attacker with Contributor-level access or higher can exploit this vulnerability to inject persistent malicious scripts into pages generated by the plugin. When other users view these pages, the injected scripts execute in their browsers, potentially leading to information disclosure or session hijacking. The vulnerability does not impact availability but affects confidentiality and integrity to a limited extent. There are no known exploits in the wild at this time.

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 vulnerable plugin to prevent exploitation. Monitor for updates from the vendor or security community regarding patches or temporary mitigations.
