GHSA-8278-88vv-x98r is a medium-severity (CVSS 5) Deserialization of Untrusted Data vulnerability in tenable-jira-cloud. O3 Security confirms whether GHSA-8278-88vv-x98r is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Execution of untrusted code through config file
Real-World Exposure
tenable-jira-cloudReal-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
It is possible to run arbitrary commands through the yaml.load() method. This could allow an attacker with local access to the host to run arbitrary code by running the application with a specially crafted YAML configuration file.
Workarounds
Manually adjust yaml.load() to yaml.safe_load()

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for tenable-jira-cloud. 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 tenable-jira-cloud to 1.1.21 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-8278-88vv-x98r 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-8278-88vv-x98r 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-8278-88vv-x98r. 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-8278-88vv-x98r in your dependencies?
O3 detects GHSA-8278-88vv-x98r across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
