Description
Bifrost is a heterogeneous middleware that synchronizes MySQL, MariaDB to Redis, MongoDB, ClickHouse, MySQL and other services for production environments. Versions prior to 1.8.8-release are subject to authentication bypass in the admin and monitor user groups by deleting the X-Requested-With: XMLHttpRequest field in the request header. This issue has been patched in 1.8.8-release. There are no known workarounds.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/brokercap/Bifrost. 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/brokercap/Bifrost to 1.8.7-release or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-39267 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-2022-39267 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-2022-39267. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
