@strapi/plugin-content-managernpmDescription
Strapi is the an open-source headless content management system. Prior to version 4.12.1, field level permissions are not respected in the relationship title. If an actor has relationship title and the relationship shows a field they don't have permission to see, the field will still be visible. Version 4.12.1 has a fix for this issue.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @strapi/plugin-content-manager. 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-content-manager to 4.12.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-37263 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-2023-37263 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-2023-37263. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
