CVE-2024-2474 is a stored cross-site scripting vulnerability in the jp2112 Standout Color Boxes and Buttons WordPress plugin, affecting all versions up to 0.7.0. The issue stems from improper neutralization of input during web page generation (CWE-79), specifically in the 'color-button' shortcode, where user-supplied attributes are not properly sanitized or escaped. Authenticated users with contributor or higher permissions can exploit this to inject arbitrary JavaScript that executes in the context of users viewing the injected pages. The vulnerability 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), reflecting network attack vector, low attack complexity, and partial impact on confidentiality and integrity with no impact on availability.

An attacker with contributor-level or higher permissions can inject persistent malicious scripts into pages via 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 vulnerability affects confidentiality and integrity but does not impact availability. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level permissions to trusted users only and consider disabling or removing the Standout Color Boxes and Buttons plugin if possible. Monitor for updates from the plugin vendor or WordPress security advisories to apply any forthcoming patches promptly.
