CVE-2025-5144: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in stellarwp The Events Calendar
The The Events Calendar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘data-date-*’ parameters in all versions up to, and including, 6.13.2 due to insufficient input sanitization and output escaping. 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-2025-5144 is a stored cross-site scripting vulnerability in the The Events Calendar plugin for WordPress, affecting all versions up to and including 6.13.2. The issue is due to improper neutralization of input during web page generation, specifically via the ‘data-date-*’ parameters. Authenticated attackers with Contributor-level privileges or higher can inject arbitrary web scripts that execute when users access the injected pages. This vulnerability is classified under CWE-79 and has a CVSS 3.1 score of 6.4 (medium severity). No patch or official remediation information is currently available.
Potential Impact
Successful exploitation allows authenticated users with Contributor-level access or above to inject and execute arbitrary scripts in the context of the affected website. This can lead to information disclosure or user session manipulation but does not impact availability. The vulnerability requires authentication and does not allow unauthenticated remote code execution.
Mitigation Recommendations
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 additional input validation or web application firewall rules to detect and block malicious payloads targeting the ‘data-date-*’ parameters.
