Description
Summary:
A open redirect vulnerability exists in the loading endpoint, allowing attackers to redirect authenticated users to arbitrary external URLs via the "next" parameter.
Details:
The loading endpoint accepts and uses an unvalidated "next" parameter for redirects:
PoC:
Visit: /loading?next=https://google.com while authenticated. The page will redirect to google.com.
Impact:
This vulnerability could be used in phishing attacks by redirecting users from a legitimate application URL to malicious sites.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/bunkerity/bunkerweb. 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 github.com/bunkerity/bunkerweb to 1.5.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-q9rr-h3hx-m87g 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-q9rr-h3hx-m87g 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-q9rr-h3hx-m87g. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
