The Page Builder: Pagelayer WordPress plugin suffers from a reflected XSS vulnerability via the 'login_url' parameter due to improper input neutralization. This allows unauthenticated attackers to inject malicious scripts that execute when an authenticated user interacts with a crafted link. Successful exploitation requires valid credentials and user interaction. The vulnerability affects all versions up to 2.0.0 and is rated medium severity (CVSS 4.7). No patch or vendor advisory has been provided to confirm remediation status.

An attacker who can supply valid credentials and trick an authenticated user into clicking a malicious link can execute arbitrary scripts in the context of that user. This could lead to limited confidentiality and integrity impacts such as session hijacking or unauthorized actions performed with the user's privileges. There is no indication of availability impact. No known exploits have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should exercise caution with links involving the 'login_url' parameter and restrict access to trusted users. Monitor vendor channels for updates and apply patches promptly once released.
