CVE-2024-8045 is a stored cross-site scripting vulnerability in the Advanced WordPress Backgrounds plugin for WordPress, affecting all versions up to and including 1.12.3. The issue stems from improper neutralization of input in the 'imageTag' parameter, allowing authenticated users with Contributor-level permissions or higher to inject arbitrary web scripts. These scripts execute in the context of users who access the injected pages, potentially leading to session hijacking or other script-based attacks. The vulnerability has a CVSS 3.1 score of 6.4, reflecting medium severity. No patch or official remediation guidance is currently available from the vendor, and the plugin is not a cloud service.

An attacker with Contributor-level or higher access can exploit this vulnerability to inject malicious scripts that execute in the browsers of 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. Availability is not impacted. No known exploits are reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Contributor-level access to trusted users only and consider removing or disabling the Advanced WordPress Backgrounds plugin if possible to reduce risk.
