CVE-2024-11877 is a stored cross-site scripting vulnerability in the Cricket Live Score WordPress plugin (wpscore) affecting all versions up to 2.0.2. The issue stems from improper neutralization of input in the 'cricket_score' shortcode, where user-supplied attributes are not properly sanitized or escaped before being rendered in web pages. Authenticated attackers with contributor-level privileges or higher can exploit this to inject arbitrary JavaScript that executes in the context of users viewing the injected pages. This vulnerability can lead to limited confidentiality and integrity impacts but does not affect availability.

An attacker with contributor-level or higher access can inject persistent malicious scripts into pages using the vulnerable shortcode. These scripts execute in the browsers of users who view the compromised pages, potentially leading to theft of session tokens, defacement, or other client-side impacts. The CVSS score of 6.4 reflects a medium severity with low complexity and no user interaction required. There is no indication of availability impact. No known exploits in the wild have been reported.

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 disabling or removing the Cricket Live Score plugin if possible. Monitor for updates from the vendor or plugin maintainers and apply patches promptly once available.
