silverstripe/framework ChangePasswordForm does not check Member::canLogIn()

GHSA-p5h2-vr99-xm99

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (silverstripe/framework 3.4.1, 3.3.3, 3.2.5, 3.1.20), 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.

After performing a password reset, ChangePasswordForm::doChangePassword() logs in the user without checking Member::canLogIn(). This presents an issue for sites that are using the extension point in that method to deny access to users (for example members that have not been “approved”, or members that have had their access revoked temporarily). It looks like Member::canLogIn() was originally designed to only be used for checking whether the user is locked out (due to too many incorrect login attempts) but has been opened up to other uses.

# Patch Next advisory brief: GHSA-p5h2-vr99-xm99

Advisory: silverstripe/framework ChangePasswordForm does not check `Member::canLogIn()`
IDs: GHSA-p5h2-vr99-xm99
Record: https://patchnext.com/advisories/ghsa-p5h2-vr99-xm99 (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: Medium (CVSS 4.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: silverstripe/framework 3.4.1, 3.3.3, 3.2.5, 3.1.20. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist silverstripe/framework: affected >= 3.1.19-rc1, < 3.1.20; >= 3.2.4-rc1, < 3.2.5; >= 3.3.2-rc1, < 3.3.3; >= 3.4.0-rc1, < 3.4.1; fixed in 3.1.20, 3.3.3, 3.2.5, 3.4.1

## Suggested inspection (read-only)
- Packagist silverstripe/framework: 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 silverstripe/framework.
- 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.
