Summary
The ThirstyAffiliates WordPress plugin, an affiliate link management tool, is affected when used with block themes, allowing unauthenticated attackers to submit comments that inject malicious scripts into pages. When a visitor opens an affected page, the injected script can run in their browser, potentially compromising their session or redirecting them to harmful content.

Read the original description
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.
