Description
The Grav API plugin (getgrav/grav-plugin-api, bundled with Grav 2.0) before version 1.0.14 (fixed in 1.0.15) contains a missing authorization vulnerability in BlueprintPathResolver::resolveUserScope(). The method gates the users/<name> scope on the account's raw super-admin ACL flag (access.api.super) instead of validating the presented API key's actual scope. An attacker holding an API key scoped only to api.media.write minted on a super-admin account can bypass the authorization check and, via POST /blueprint-upload or GET /blueprint-files, write a file into another user's scope (in the shared user/accounts/ directory, constrained to image extensions by assertSafeExtension()) and browse that scope's file listing, despite the key not being granted api.users.write.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. 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.
Remediation status
No patched version of the affected component has shipped for CVE-2026-75832 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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-2026-75832 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-2026-75832. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
