CVE-2025-65956 Details
Description
Formwork is a flat file-based Content Management System (CMS). Prior to version 2.2.0, inserting unsanitized data into the blog tag field results in stored cross‑site scripting (XSS). Any user with credentials to the Formwork CMS who accesses or edits an affected blog post will have attacker‑controlled script executed in their browser. The issue is persistent and impacts privileged administrative workflows. This issue has been patched in version 2.2.0.
A stored cross-site scripting vulnerability has been identified in Formwork CMS versions prior to 2.2.0. The issue arises from the blog tag field, where unsanitized data can be inserted, leading to the execution of attacker-controlled scripts in the browser of any user with CMS credentials who accesses or edits the affected blog post. This vulnerability is persistent and disrupts administrative workflows by causing the injected script to execute whenever an attempt is made to remove the malicious tag, effectively locking the user out of managing standard tags.
Users can update to Formwork CMS version 2.2.0 or later, where this vulnerability has been patched.
