CVE-2024-6931
Published: 27 September 2024
Summary
CVE-2024-6931 is a high-severity Cross-site Scripting (CWE-79) vulnerability in Stellarwp The Events Calendar. Its CVSS base score is 7.2 (High).
Operationally, ranked in the top 2.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
The Events Calendar plugin for WordPress is vulnerable to stored cross-site scripting in the RSVP name field across all versions through 6.6.3. The flaw stems from insufficient input sanitization and output escaping, allowing arbitrary script injection that persists and executes in the browser of subsequent visitors.
Unauthenticated attackers can supply malicious payloads through the RSVP name field on event pages. Once stored, the scripts run with the privileges of any user who views the affected content, enabling actions such as session hijacking or unauthorized data access within the site context.
The referenced WordPress plugin changeset and developer changelog document a fix released after version 6.6.3, while the Wordfence advisory recommends immediate update to a patched release as the primary mitigation. The associated EPSS score has remained flat at 0.3546 with no observed upward trajectory since disclosure.
