@dependencytrack/frontend vulnerable to Persistent Cross-Site-Scripting via welcome message
Exploitation Status
No confirmed exploitation observed yet
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.
Exploitation and automatability from CISA’s SSVC triage for GHSA-7xvh-c266-cfr5.
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-7xvh-c266-cfr5 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 377,166 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.
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
@dependencytrack/frontendnpmDescription
Description
Since version 4.12.0, Dependency-Track users with the SYSTEM_CONFIGURATION permission can configure a "welcome message", which is HTML that is to be rendered on the login page for branding purposes.
When rendering the welcome message, Dependency-Track versions before 4.13.6 did not properly sanitize the HTML, allowing arbitrary JavaScript to be executed.
Impact
Users with the SYSTEM_CONFIGURATION permission (i.e., administrators), can exploit this weakness to execute arbitrary JavaScript for users browsing to the login page.
Patches
The issue has been fixed in version 4.13.6.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @dependencytrack/frontend, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update @dependencytrack/frontend to 4.13.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7xvh-c266-cfr5 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-7xvh-c266-cfr5 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-7xvh-c266-cfr5. 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-7xvh-c266-cfr5 in your dependencies?
O3 Security finds GHSA-7xvh-c266-cfr5 across npm dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
