Photo Gallery by 10Web - Security Vulnerability (CVE-2026-12865)

Q: Am I affected by this vulnerability?

You are affected if your site runs Photo Gallery by 10Web. Versions below 1.8.44 are vulnerable; that release and later are not. No account is needed to exploit this, so a public site is reachable by anyone.

Q: How do I fix it?

Update Photo Gallery by 10Web to version 1.8.44 or later. That is the complete fix. Until you can update, Request / payload inspection (WAF) in Hack Halt ProSecure contains this class of attack at the request layer.

Q: What can an attacker actually do?

This is a Cross-Site Scripting (XSS) flaw. An attacker who exploits it can run script in a visitor's browser, stealing sessions or planting an administrator account.

Vulnerability CVE-2026-12865 PLUGIN photo-gallery-by-10web HIGH

The Photo Gallery by 10Web WordPress plugin before 1.8.44 does not escape two request parameters before reflecting them into input-attribute values on its admin pages (one on the Shortcode page, one on the Galleries/Albums list page), so an unauthenticated attacker can craft a link that, when opened by a logged-in administrator (or, for the first sink, a contributor), executes arbitrary JavaScript in the victim's authenticated session via an auto-firing onfocus handler. The Galleries/Albums sink renders only when the site has more than 20 galleries/albums (the normal state of a populated install).

Primary risk drivers: low-bar exploit prerequisites

Mitigation Recommendations

Validate affected product versions, prioritize patching, and monitor references for vendor remediation guidance. If immediate patching is not possible, apply compensating controls and limit exposure of vulnerable surfaces.

Detection & Monitoring

Track authentication anomalies, unexpected file writes, and suspicious plugin API activity around affected components.

What to do about this

Patch promptly The consequence is significant even where an attacker needs a foothold first.

Fix it

Update Photo Gallery by 10Web to 1.8.44 or later.

That is the complete fix. Everything below is what protects you in the meantime.

Cannot update today? Request / payload inspection (WAF) in Hack Halt ProSecure blocks this class of attack before WordPress processes the request.

Inspect request parameters and bodies for injection, traversal and file-inclusion payloads, and refuse the request rather than logging it.
