GHSA-rv9v-r4vm-gj8x is a high-severity (CVSS 7.5) Out-of-bounds Write vulnerability in miniscript. O3 Security confirms whether GHSA-rv9v-r4vm-gj8x is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description
The Miniscript (aka rust-miniscript) library for Rust allows stack consumption because it does not properly track tree depth.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🦀crates.io | miniscript | ≥ 12.0.0&&< 12.2.0 | 12.2.0 |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for miniscript. 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 miniscript to 12.2.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rv9v-r4vm-gj8x 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-rv9v-r4vm-gj8x 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-rv9v-r4vm-gj8x. 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-rv9v-r4vm-gj8x in your dependencies?
O3 detects GHSA-rv9v-r4vm-gj8x across crates.io dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
