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.
How urgent is this, really
GHSA-ch4j-vcf5-58x5 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 379,842 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description
Cockpit CMS through version 2.14.0, patched in commit 72a83fc, contains a stored cross-site scripting vulnerability in the Set field type's Display template option, where the template string is processed by the $interpolate function using new Function() and rendered via Vue's v-html directive without sanitization. An attacker with content/:models/manage permission can inject arbitrary JavaScript into the Display template, which executes in the browser of any user viewing the collection items list.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for cockpit-hq/cockpit, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of cockpit-hq/cockpit has shipped for GHSA-ch4j-vcf5-58x5 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-ch4j-vcf5-58x5 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-ch4j-vcf5-58x5. 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-ch4j-vcf5-58x5 in your dependencies?
O3 Security finds GHSA-ch4j-vcf5-58x5 across Packagist dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
