Description
In versions prior to 3.26.0 and prior to 4.11.0 of the "scheb/two-factor-bundle" project, a security vulnerability allowed attackers to bypass two-factor authentication (2FA) using the remember_me cookie. When the remember_me checkbox was used during login, a "REMEMBERME" cookie was created. Upon redirection to the 2FA page, attackers could manipulate the SESSIONID key, granting access to the homepage "/" and gaining authentication without completing 2FA.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for scheb/two-factor-bundle. 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 scheb/two-factor-bundle to 4.11.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-9phw-7h96-q3rv 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-9phw-7h96-q3rv 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-9phw-7h96-q3rv. 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-9phw-7h96-q3rv in your dependencies?
O3 detects GHSA-9phw-7h96-q3rv across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
