CVE-2023-48218
MEDIUMCVE-2023-48218 is a medium-severity (CVSS 5.3) CWE-863 vulnerability in strapi-plugin-protected-populate. O3 Security confirms whether CVE-2023-48218 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Strapi Protected Populate Plugin leaking fields if the request fields where empty or only fields selected where not populatable
Blast Radius
strapi-plugin-protected-populateReal-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
The Strapi Protected Populate Plugin protects get endpoints from revealing too much information. Prior to version 1.3.4, users were able to bypass the field level security. Users who tried to populate something that they didn't have access to could populate those fields anyway. This issue has been patched in version 1.3.4. There are no known workarounds.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for strapi-plugin-protected-populate. 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-protected-populate to 1.3.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-48218 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-2023-48218 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-2023-48218. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
