What is CVE-2026-107657?

CVE-2026-107657 is a high-severity cross-site scripting vulnerability in HivePress – Business Directory, Listings & Classified Ads Plugin, published on 10 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

The HivePress – Business Directory, Listings & Classified Ads Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the '<custom user attribute field name, e.g. profile_test>' parameter in all versions up to, and including, 1.7.31 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires an administrator to have configured a text-type custom user attribute whose display format places %value% inside an HTML attribute context (e.g., the documented pattern <a href="%value%">Custom link</a>), and for front-end user profiles to be enabled — both of which reflect the plugin's standard, documented configuration.

Weakness: CWE-79
