GHSA-9jxq-5x44-gx23 is a medium-severity (CVSS 4.3) CWE-704 vulnerability in keylime. O3 Security confirms whether GHSA-9jxq-5x44-gx23 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Keylime registrar is vulnerable to Denial-of-Service attack when updated to version 7.12.0
Real-World Exposure
keylimeReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
Impact
The Keylime registrar implemented more strict type checking on version 7.12.0. As a result, when updated to version 7.12.0, the registrar will not accept the format of the data previously stored in the database by versions >= 7.8.0, raising an exception.
This makes the Keylime registrar vulnerable to a Denial-of-Service attack in an update scenario, as an attacker could populate the registrar database by creating multiple valid agent registrations with different UUIDs while the version is still < 7.12.0. Then, when the Keylime registrar is updated to the 7.12.0 version, any query to the database matching any of the entries populated by the attacker will result in failure.
Patches
Users should upgrade to versions >= 7.12.1
Workarounds
- Remove the registrar database and re-register all agents

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for keylime. 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 keylime to 7.12.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-9jxq-5x44-gx23 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-9jxq-5x44-gx23 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-9jxq-5x44-gx23. 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-9jxq-5x44-gx23 in your dependencies?
O3 detects GHSA-9jxq-5x44-gx23 across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
