Description
bunkerweb is an Open-source and next-generation Web Application Firewall (WAF). A open redirect vulnerability exists in the loading endpoint, allowing attackers to redirect authenticated users to arbitrary external URLs via the "next" parameter. The loading endpoint accepts and uses an unvalidated "next" parameter for redirects. Ex. visiting: /loading?next=https://google.com while authenticated will cause the page will redirect to google.com. This vulnerability could be used in phishing attacks by redirecting users from a legitimate application URL to malicious sites. This issue has been addressed in version 1.5.11. Users are advised to upgrade. There are no known workarounds for this vulnerability.

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 CVE-2024-53264 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 CVE-2024-53264 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 CVE-2024-53264. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
