HIGHConnect-CMS has DOM-based Cross-Site Scripting (XSS) in the Cabinet Plugin List View
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description
Security Advisory — Cabinet Plugin (DOM-based XSS)
Summary
A DOM-based Cross-Site Scripting (XSS) issue exists in the Cabinet Plugin list view.
Affected Versions
- 1.x series: >= 1.35.0, <= 1.41.0
- 2.x series: >= 2.35.0, <= 2.41.0
Patched Versions
- 1.41.1
- 2.41.1
Description
In the Cabinet Plugin list view, DOM-based Cross-Site Scripting (XSS) could occur due to how saved names were rendered. If exploited, arbitrary script could run in the victim's browser, which may lead to unauthorized actions or information theft. Exploitation requires that the attacker be able to reach the affected functionality as an authenticated user. Users affected by this vulnerability should update to a fixed version.
Solution
Update to the fixed version. For the 1.x series, update to 1.41.1 or later. For the 2.x series, update to 2.41.1 or later.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for opensource-workshop/connect-cms. 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.
Fix
Update opensource-workshop/connect-cms to 1.41.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-cmfh-mpmf-fmq4 is resolved across your whole dependency graph.
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.
How O3 protects you
O3 pinpoints whether GHSA-cmfh-mpmf-fmq4 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-cmfh-mpmf-fmq4. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-cmfh-mpmf-fmq4 in your dependencies?
O3 detects GHSA-cmfh-mpmf-fmq4 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
