Envira Gallery - Security Vulnerability (CVE-2026-104680)

Q: Am I affected by this vulnerability?

You are affected if your site runs Envira Gallery. Versions below 1.16.2 are vulnerable; that release and later are not.

Q: How do I fix it?

Update Envira Gallery to version 1.16.2 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 Broken Access Control flaw. An attacker who exploits it can reach actions or data that should have been restricted to someone else.

What to do about this

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

Fix it

Update Envira Gallery to 1.16.2 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.
