CVE-2026-55092
CVE-2026-55092 is a Path Traversal vulnerability in github.com/aquasecurity/trivy. O3 Security confirms whether CVE-2026-55092 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Trivy: Path traversal via a crafted vulnerability database or other downloaded artifacts
Real-World Exposure
github.com/aquasecurity/trivyReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
Trivy is a security scanner. Prior to 0.71.1, when Trivy downloads an OCI artifact, it uses the org.opencontainers.image.title annotation from the artifact manifest as the destination filename without validation. An attacker who can make Trivy fetch an attacker-controlled artifact can supply a crafted annotation that resolves to a path outside the intended destination, causing Trivy to write the layer content to an arbitrary location on the host filesystem. This vulnerability is fixed in 0.71.1.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/aquasecurity/trivy. 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 github.com/aquasecurity/trivy to 0.71.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-55092 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-2026-55092 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-2026-55092. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
