What is CVE-2026-19797?

The User Access Manager plugin for WordPress has a vulnerability that allows unauthenticated attackers to leverage the 'tab_group_section' parameter for reflected cross-site scripting (XSS). This occurs due to improper input sanitization and output escaping in all versions up to and including 2.3.18. Attackers can exploit this by tricking a user into clicking a specially crafted link, potentially allowing them to execute malicious scripts within the user's browser context.

Affected Version(s)

User Access Manager 0 <= 2.3.18
