GHSA-m6vv-vcj8-w8m7
MEDIUMGHSA-m6vv-vcj8-w8m7 is a medium-severity (CVSS 5.9) CWE-915 vulnerability in drupal/core. O3 Security confirms whether GHSA-m6vv-vcj8-w8m7 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description
Improperly Controlled Modification of Dynamically-Determined Object Attributes vulnerability in Drupal Drupal core allows Object Injection. This issue affects Drupal core: from 8.0.0 before 10.4.9, from 10.5.0 before 10.5.6, from 11.0.0 before 11.1.9, from 11.2.0 before 11.2.8.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for drupal/core. 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 drupal/core to 10.4.9 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-m6vv-vcj8-w8m7 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 GHSA-m6vv-vcj8-w8m7 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 GHSA-m6vv-vcj8-w8m7. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-m6vv-vcj8-w8m7 in your dependencies?
O3 detects GHSA-m6vv-vcj8-w8m7 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
