CVE-2026-6243: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in shabti Frontend Admin by DynamiApps

CVE-2026-6243 is a stored cross-site scripting vulnerability in the Frontend Admin by DynamiApps WordPress plugin. The issue stems from the 'get_dynamic_values' function performing text-level find-and-replace operations on post content without proper HTML parsing, allowing authenticated users with Contributor-level permissions or above to inject arbitrary web scripts. These scripts execute in the context of any user who accesses the injected page, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all plugin versions from 0 up to and including 3.28.36.

An attacker with Contributor-level or higher access can inject malicious scripts into pages, which execute in the browsers of users who view those pages. This can lead to information disclosure, session hijacking, or other client-side attacks. The vulnerability does not affect availability but impacts confidentiality and integrity. The CVSS 3.1 score is 6.4 (medium severity), reflecting network attack vector, low attack complexity, low privileges required, no user interaction, and partial impact on confidentiality and integrity.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict Contributor-level access to trusted users only and consider disabling or limiting the use of the vulnerable plugin. Monitor official vendor channels for updates and apply any released patches promptly.
