CVE-2024-13463: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in thesiim SeatReg
The SeatReg plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'seatreg' shortcode in all versions up to, and including, 1.56.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
AI Analysis
Technical Summary
CVE-2024-13463 is a stored cross-site scripting vulnerability in the thesiim SeatReg WordPress plugin, affecting all versions up to and including 1.56.0. The issue arises from improper neutralization of user-supplied input in the 'seatreg' shortcode, allowing authenticated users with contributor or higher privileges to inject arbitrary scripts.

The vulnerability is classified under CWE-79 and has a CVSS 3.1 base score of 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N).
Potential Impact
An attacker with contributor-level access or higher can exploit this vulnerability to inject persistent malicious scripts into pages using the 'seatreg' shortcode. This can lead to limited confidentiality and integrity impacts, such as theft of user session data or manipulation of page content. There is no impact on availability reported. The vulnerability affects all users who view the compromised pages.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, limit contributor-level access to trusted users only and consider removing or disabling the SeatReg plugin if possible. Monitor official thesiim or WordPress plugin repositories for updates addressing this vulnerability.
