Description
Arbitrary file write as the OSV-SCALIBR user on the host system via a path traversal vulnerability when using OSV-SCALIBR's unpack() function for container images. Particularly, when using the CLI flag --remote-image on untrusted container images.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/google/osv-scalibr, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/google/osv-scalibr to 0.2.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-5981 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2025-5981 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2025-5981. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2025-5981 in your dependencies?
O3 Security finds CVE-2025-5981 across Go dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
