Summary

CVE-2024-12633 is a high-severity Cross-site Scripting (CWE-79) vulnerability in Wordpress (inferred from references). Its CVSS base score is 7.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 18.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-15 (Information Output Filtering).

Deeper analysis

CVE-2024-12633 is a reflected cross-site scripting (XSS) vulnerability in the JoomSport – for Sports: Team & League, Football, Hockey & more plugin for WordPress, affecting all versions up to and including 5.6.17. The issue arises from insufficient input sanitization and output escaping of the 'page' parameter, allowing arbitrary web scripts to be injected into pages.

Unauthenticated attackers can exploit this vulnerability remotely with low attack complexity and no privileges required, but it necessitates user interaction such as clicking a malicious link. Successful exploitation leads to script execution in the victim's browser, with a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L), indicating low impacts on confidentiality, integrity, and availability but elevated severity due to changed scope.
