CVE-2024-13390 is a stored cross-site scripting vulnerability in the giuliopanda ADFO – Custom data in admin dashboard WordPress plugin affecting all versions up to 1.9.1. The vulnerability exists due to improper neutralization of input (CWE-79) in the 'adfo_list' shortcode, allowing authenticated users with contributor or higher privileges to inject arbitrary web scripts. These scripts execute in the context of users who access the injected pages, potentially leading to session hijacking or other script-based attacks. The CVSS 3.1 vector indicates network attack vector, low attack complexity, privileges required, no user interaction, and a scope change with low confidentiality and integrity impact but no availability impact.

An attacker with contributor-level or higher access can inject persistent malicious scripts into pages via the vulnerable shortcode. These scripts execute in the browsers of users viewing the affected pages, potentially compromising user sessions or performing unauthorized actions within the context of the victim's privileges. The impact is limited to confidentiality and integrity with no direct availability impact. No known active exploitation has 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. Consider disabling or removing the vulnerable plugin if possible. Monitor for updates from the vendor or plugin author and apply official patches promptly once available.
