CVE-2024-3337 is a stored cross-site scripting vulnerability in the Colibri Page Builder plugin for WordPress, specifically in the 'colibri_breadcrumb_element' shortcode. The issue is due to improper neutralization of input during web page generation, allowing authenticated users with contributor or higher privileges to inject arbitrary scripts. These scripts execute in the context of users viewing the compromised pages, potentially leading to information disclosure or session hijacking. The vulnerability affects all versions up to and including 1.0.272. The CVSS 3.1 base score is 6.4 with vector AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N, indicating network attack vector, low attack complexity, required privileges at contributor level, no user interaction, scope changed, and low impact on confidentiality and integrity, with no impact on availability.

An attacker with contributor-level access or higher can inject malicious scripts that execute in the browsers of users who visit the affected pages. This can lead to partial confidentiality and integrity impacts, such as theft of user data or manipulation of page content. There is no direct impact on availability. The vulnerability does not require user interaction beyond visiting the injected page. 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 available, restrict contributor-level access to trusted users only and consider disabling or limiting use of the 'colibri_breadcrumb_element' shortcode. Monitor vendor channels for updates and apply patches promptly once released.
