scheb/two-factor-bundle bypass two-factor authentication with remember-me option

GHSA-9phw-7h96-q3rv

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (scheb/two-factor-bundle 4.11.0, 3.26.0), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

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 rememberme cookie. When the rememberme 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.

# Patch Next advisory brief: GHSA-9phw-7h96-q3rv

Advisory: scheb/two-factor-bundle bypass two-factor authentication with remember-me option
IDs: GHSA-9phw-7h96-q3rv
Record: https://patchnext.com/advisories/ghsa-9phw-7h96-q3rv (revision 1, source checked 26 Oct 2026, 14:24 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.4)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: scheb/two-factor-bundle 4.11.0, 3.26.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist scheb/two-factor-bundle: affected >= 4.0.0, < 4.11.0; < 3.26.0; fixed in 4.11.0, 3.26.0

## Suggested inspection (read-only)
- Packagist scheb/two-factor-bundle: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on scheb/two-factor-bundle.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
