CVE-2023-22893
HIGHCVE-2023-22893 is a high-severity (CVSS 8.2) Improper Authentication vulnerability in @strapi/plugin-users-permissions. 2 public exploit references exist, so weaponization risk is real. O3 Security confirms whether CVE-2023-22893 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Strapi does not verify the access or ID tokens issued during the OAuth flow

@strapi/plugin-users-permissionsReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects npm packages — download data is not available via public APIs for these ecosystems.
Description
Strapi through 4.5.5 does not verify the access or ID tokens issued during the OAuth flow when the AWS Cognito login provider is used for authentication. A remote attacker could forge an ID token that is signed using the 'None' type algorithm to bypass authentication and impersonate any user that use AWS Cognito for authentication.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @strapi/plugin-users-permissions. 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 @strapi/plugin-users-permissions to 4.6.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-22893 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-2023-22893 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-2023-22893. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
