LOWOCI Manifest Type Confusion Issue
Blast Radius
github.com/docker/distributionReal-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
Impact
Systems that rely on digest equivalence for image attestations may be vulnerable to type confusion.
Patches
Upgrade to at least v2.8.0-beta.1 if you are running v2.x release. If you use the code from the main branch, update at least to the commit after b59a6f827947f9e0e67df0cfb571046de4733586.
Workarounds
There is no way to work around this issue without patching.
References
Due to an oversight in the OCI Image Specification that removed the embedded mediaType field from manifests, a maliciously crafted OCI Container Image can cause registry clients to parse the same image in two different ways without modifying the image’s digest by modifying the Content-Type header returned by a registry. This can invalidate a common pattern of relying on container image digests for equivalence.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/docker/distribution. 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/docker/distribution to 2.8.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-qq97-vm5h-rrhg 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-qq97-vm5h-rrhg 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-qq97-vm5h-rrhg. 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-qq97-vm5h-rrhg in your dependencies?
O3 detects GHSA-qq97-vm5h-rrhg across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
