GHSA-m2w4-8ggf-rj47
HIGHGHSA-m2w4-8ggf-rj47 is a high-severity (CVSS 8.1) vulnerability in github.com/hashicorp/vault. O3 Security confirms whether GHSA-m2w4-8ggf-rj47 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
HashiCorp Vault has a KVv2 Metadata and Secret Deletion Policy Bypass that leads to Denial-of-Service

Description
An authenticated user with access to a kvv2 path through a policy containing a glob may be able to delete secrets they were not authorized to read or write, resulting in denial-of-service. This vulnerability did not allow a malicious user to delete secrets across namespaces, nor read any secret data. Fixed in Vault Community Edition 2.0.0 and Vault Enterprise 2.0.0, 1.21.5, 1.20.10, and 1.19.16.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/hashicorp/vault. 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 github.com/hashicorp/vault has shipped for GHSA-m2w4-8ggf-rj47 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 GHSA-m2w4-8ggf-rj47 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-m2w4-8ggf-rj47. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
