Description

Summary

Inserting unsanitized data into the blog tag field in Formwork CMS 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. Because the issue is persistent and impacts privileged administrative workflows, the severity is elevated.

Details

Formwork CMS fails to properly sanitize data inserted into tags, before saving them and rendering them into the edit blog interface. When a specially crafted tag becomes saved as a tag into the system, it is unable to be removed. Any attempt to remove the tag from the affected post, causes the XSS to trigger once again.

Additionally, once the malicious tag is present, managing standard tags becomes impossible. This is due to script execution on attempted modification. This leads to a form of interface lockout where the payload continually reinserts itself due to the stored, unsafe rendering.

Impact

This is a stored cross‑site scripting (XSS) vulnerability.

This impacts all users who access the affected blog post’s edit page.

Patches

Formwork 2.2.0 ensures proper escaping of user input in tag fields.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for getformwork/formwork. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update getformwork/formwork to 2.2.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7j46-f57w-76pj is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether GHSA-7j46-f57w-76pj is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-7j46-f57w-76pj. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
