At a glance

CVE-2025-13685 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the Photo Gallery by Ays WordPress plugin, affecting versions <= 6.4.8. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 6.4.9; sites on affected versions should update now. Disclosed December 2025, reported by Deadbee.

Vulnerability Overview

The Photo Gallery by Ays plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 6.4.8. This is due to missing nonce verification on the bulk action functionality in the 'process_bulk_action()' function. This makes it possible for unauthenticated attackers to perform bulk operations (delete, publish, or unpublish galleries) via a forged request granted they can trick an administrator into performing an action such as clicking on a link.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site.

CWE-352: Cross-Site Request Forgery (CSRF)

Photo Gallery by Ays <= 6.4.8 carries this weakness at process_bulk_action(), and reaching it takes a caller who can reach the endpoint. Cross-site request forgery abuses the fact that browsers attach a victim's cookies to any request, so a state-changing action that only checks who you are, not whether you meant to act, can be triggered from another site.

An attacker who gets a logged-in user to load a crafted page can perform that action as them, with the impact scaling to whatever the victim's role is allowed to do. For Photo Gallery by Ays the fix is 6.4.9: builds <= 6.4.8 are affected, anything from 6.4.9 onward is not.

Remediation

Update to version 6.4.9, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Photo Gallery by Ays: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Photo Gallery by Ays 6.4.9 closes this, and updating the plugin is the step that ends it.
