How severe is GHSA-4m7h-34xm-4wjv?

GHSA-4m7h-34xm-4wjv has a CVSS score of 2.2/10, rated LOW. Review your exposure and patch according to your risk tolerance.

Which packages are affected by GHSA-4m7h-34xm-4wjv?

GHSA-4m7h-34xm-4wjv affects the following packages: concrete5/concrete5 (Packagist). Ecosystems affected: Packagist.

How do I fix GHSA-4m7h-34xm-4wjv?

Update concrete5/concrete5 to 9.2.7 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-4m7h-34xm-4wjv is resolved across your whole dependency graph.

How do I detect GHSA-4m7h-34xm-4wjv in my Packagist dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for concrete5/concrete5. 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.

How do I mitigate GHSA-4m7h-34xm-4wjv if there is no patch (or I can't update yet)?

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 does O3 Security protect against GHSA-4m7h-34xm-4wjv?

O3 pinpoints whether GHSA-4m7h-34xm-4wjv is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-4m7h-34xm-4wjv actively exploited in the wild?

No public exploit code has been indexed for GHSA-4m7h-34xm-4wjv yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-4m7h-34xm-4wjv?

GHSA-4m7h-34xm-4wjv has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 22th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

When was GHSA-4m7h-34xm-4wjv published, and has it been updated?

GHSA-4m7h-34xm-4wjv was published on March 5, 2024 and was last updated on September 3, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Concrete CMS version 9 before 9.2.7 is vulnerable to Stored XSS via the Name field of a Group type since there is insufficient validation of administrator provided data for that field. A rogue administrator could inject malicious code into the Name field which might be executed when users visit the affected page. The Concrete CMS security team gave this vulnerability a CVSS v3.1 score of 2.2 with a vector of AV:N/AC:H/PR:H/UI:N/S:U/C:L/I:N/A:N Concrete versions below 9 do not include group types so they are not affected by this vulnerability. Thanks Luca Fuda for reporting.
