CVE-2026-104744 Details
Description
The Independent Analytics Pro plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'utm_campaign' parameter in all versions up to, and including, 2.15.5 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. Exploitation requires the Independent Analytics Pro build to be active, as the free build nulls campaign parameters; additionally, the attacker must first visit a frontend page to obtain a server-signed payload that can be replayed with a crafted utm_campaign value against the unauthenticated /iawp/search REST endpoint, since the signature check does not cover utm_* fields.
A stored cross-site scripting vulnerability has been identified in the Independent Analytics Pro plugin for WordPress, affecting all versions through 2.15.5. The issue arises from inadequate input sanitization and output escaping, allowing unauthenticated attackers to inject arbitrary scripts via the 'utm_campaign' parameter. These scripts execute when a user accesses the compromised page. Exploitation requires the Independent Analytics Pro build, as the free version does not process campaign parameters. Additionally, the attacker must first visit a frontend page to receive a server-signed payload, which can then be replayed using a crafted 'utm_campaign' value on the unauthenticated '/iawp/search' REST endpoint, since the signature check does not apply to 'utm_*' fields.
Users are advised to update the Independent Analytics Pro plugin to version 2.16.0 or later.
