Description
A vulnerability was found in Grav CMS up to 1.7.49.5/2.0.0-beta.1. Affected by this vulnerability is the function FileCache::doGet of the file system/src/Grav/Framework/Cache/Adapter/FileCache.php of the component Cache Value Handler. The manipulation results in deserialization. The attack may be launched remotely. The attack requires a high level of complexity. The exploitation appears to be difficult. The exploit has been made public and could be used. Upgrading to version 2.0.0-beta.2 addresses this issue. The patch is identified as c66dfeb5f. The affected component should be upgraded.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for getgrav/grav. 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 getgrav/grav to 2.0.0-beta.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-7317 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-2026-7317 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-2026-7317. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
