Strapi has a rate limit bypass on users-permissions plugin via attacker-controlled email keying

CVE-2025-64526GHSA-7mqx-wwh4-f9fw

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (@strapi/plugin-users-permissions 5.45.0), 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.

An unauthenticated attacker could include an arbitrary email value in the request body to obtain a fresh rate-limit key per request, effectively bypassing per-IP throttling on those routes and enabling high-volume credential brute-force, password-reset code brute-force, and credential-stuffing attempts. The rate-limit key was constructed as…

# Patch Next advisory brief: CVE-2025-64526

Advisory: Strapi has a rate limit bypass on users-permissions plugin via attacker-controlled email keying
IDs: CVE-2025-64526, GHSA-7mqx-wwh4-f9fw
Record: https://patchnext.com/advisories/cve-2025-64526 (revision 3, source checked 26 Oct 2026, 12:52 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.9)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: @strapi/plugin-users-permissions 5.45.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm @strapi/plugin-users-permissions: affected <= 5.44.0; fixed in 5.45.0

## Suggested inspection (read-only)
- `npm ls @strapi/plugin-users-permissions --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## 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 @strapi/plugin-users-permissions.
- 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
- Verified: https://osv.dev/vulnerability/GHSA-7mqx-wwh4-f9fw (OSV record GHSA-7mqx-wwh4-f9fw lists affected ranges: npm @strapi/plugin-users-permissions >=0 <5.45.0 (fixed))
- Verified: https://github.com/advisories/GHSA-7mqx-wwh4-f9fw (GitHub-reviewed advisory GHSA-7mqx-wwh4-f9fw lists affected ranges: npm @strapi/plugin-users-permissions >=0 <=5.44.0)

Commands are suggestions: review each one before running it.
