CVE-2024-13578 is a stored cross-site scripting vulnerability in the WP-BibTeX plugin for WordPress, affecting all versions up to 3.0.1. The issue arises from improper neutralization of user-supplied input in the 'WpBibTeX' shortcode, allowing authenticated users with contributor or higher privileges to inject arbitrary web scripts. These scripts execute in the context of any user who accesses the injected page, potentially leading to information disclosure or session hijacking. The vulnerability has a CVSS 3.1 base score of 6.4 (medium severity), with attack vector network, low attack complexity, privileges required at the contributor level, no user interaction, and impacts confidentiality and integrity with no impact on availability. No vendor patch or official fix has been disclosed yet.

An attacker with contributor-level access or higher can inject persistent malicious scripts into pages via the vulnerable shortcode. These scripts execute in the browsers of users who view the compromised pages, potentially leading to unauthorized actions, data theft, or session compromise. The vulnerability impacts confidentiality and integrity but does not affect availability. There are no known active exploits reported.

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 disabling or removing the WP-BibTeX plugin if possible. Implementing web application firewall (WAF) rules to detect and block suspicious shortcode inputs may provide temporary mitigation.
