## What is CVE-2026-84096?

CVE-2026-84096 is a high-severity cross-site scripting vulnerability in Unknown wp-review-slider-pro, published on 26 Sep 2026. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

The wp-review-slider-pro WordPress plugin before 12.7.12 does not perform a capability check on the AJAX handler that saves its review submission forms, and the nonce protecting it is generated for every visitor, allowing any authenticated user, such as a subscriber, to overwrite a live form with field values that are output without escaping on public pages, leading to Stored Cross-Site Scripting.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)
