CVE-2024-11413 is a stored cross-site scripting vulnerability in the HostFact bestelformulier integratie WordPress plugin affecting all versions up to 1.1. The issue arises from improper neutralization of input in the 'bestelformulier' shortcode, allowing authenticated contributors or higher to inject arbitrary scripts. These scripts execute in the context of users who access the compromised pages, potentially leading to session hijacking or other client-side impacts. The CVSS 3.1 vector indicates network attack vector, low attack complexity, required privileges at the contributor level, no user interaction, and impacts on confidentiality and integrity but not availability.

The vulnerability allows authenticated users with contributor-level privileges or higher to inject and store malicious scripts that execute in other users' browsers when viewing affected pages. This can lead to unauthorized disclosure of information or manipulation of content within the affected site context. There is no indication of impact on system availability. 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. Consider disabling or removing the HostFact bestelformulier integratie plugin if it is not essential. Monitor for updates from the vendor regarding patches or official mitigations.
