Summary

The ThirstyAffiliates plugin for WordPress in versions up to and including 3.12.1 is vulnerable to Stored Cross-Site Scripting via the 'comment' parameter. An unauthenticated attacker can inject arbitrary web scripts that execute when a user accesses an injected page.

Risk Assessment

An attacker can execute arbitrary JavaScript in visitors' browsers, potentially leading to session or data theft. This requires a block theme and one prior approved comment by the attacker.

Recommendation

Update the ThirstyAffiliates plugin to a version newer than 3.12.1 and consider restricting automatic comment approval.

Other vulnerabilities in ThirstyAffiliates WordPress plugin

CVE-2026-97314Medium
The ThirstyAffiliates WordPress plugin before 3.12.1 does not check the status or type of the object requested by its link redirect tracking handler, allowing unauthenticated attackers to disclose the destination URLs of unpublished affiliate links and to record fabricated click statistics.

Original NVD description (English source)

The ThirstyAffiliates – Affiliate Links, Link Branding, Link Tracking & Marketing Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'comment' parameter in all versions up to, and including, 3.12.1 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 vulnerability is only exploitable on block themes (such as Twenty Twenty-Five) where the Comment Content block causes comment HTML to flow through render_block, triggering the plugin's transformer. Additionally, a successful attack requires the attacker to have had one prior comment approved, after which subsequent crafted comments are auto-approved and rendered publicly.
