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-6qvv-pj99-48qm 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 377,636 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.
@adonisjs/http-servernpm@adonisjs/corenpmDescription
Impact
The response.redirect().back() method in @adonisjs/http-server is vulnerable to open redirects. The method reads the Referer header from the incoming HTTP request and redirects to that URL without validating the host. An attacker who can influence the Referer header (for example, by linking a user through an attacker-controlled page before a form submission) can cause the application to redirect users to a malicious external site.
This affects all AdonisJS applications that use response.redirect().back() or response.redirect('back').
The vulnerability is classified as CWE-601: URL Redirection to Untrusted Site ('Open Redirect').
Patches
This has been fixed in @adonisjs/http-server version 8.2.0. The back() method now validates the Referer header's host against the request's own Host header. Referrers from unrecognized hosts are rejected and the redirect falls back to / (or a developer-provided fallback URL).
Applications that operate across multiple domains can configure additional trusted hosts via the redirect.allowedHosts option in config/app.ts.
Users should upgrade to @adonisjs/http-server@^8.2.0 (or @adonisjs/core@^7.4.0 if using the core meta-package).
Workarounds
If upgrading is not immediately possible, avoid using response.redirect().back() in routes that are reachable by unauthenticated users or from pages that accept external traffic. Instead, redirect to a known safe path explicitly using response.redirect().toPath('/dashboard').

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @adonisjs/http-server, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update @adonisjs/http-server to 8.2.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6qvv-pj99-48qm 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-6qvv-pj99-48qm can be triaged on real exposure rather than presence alone.
Tailored to GHSA-6qvv-pj99-48qm. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
