GHSA-99w6-3xph-cx78
MEDIUMGHSA-99w6-3xph-cx78 is a medium-severity (CVSS 5.5) Improper Input Validation vulnerability in ansible-core. O3 Security confirms whether GHSA-99w6-3xph-cx78 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Ansible-Core vulnerable to content protections bypass

Description
A flaw was found in Ansible-Core. This vulnerability allows attackers to bypass unsafe content protections using the hostvars object to reference and execute templated content. This issue can lead to arbitrary code execution if remote data or module outputs are improperly templated within playbooks.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐍PyPI | ansible-core | ≥ 2.18.0b1&&< 2.18.1rc1 | 2.18.1rc1 |
| 🐍PyPI | ansible-core | ≥ 2.17.0b1&&< 2.17.7rc1 | 2.17.7rc1 |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ansible-core. 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 ansible-core to 2.18.1rc1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-99w6-3xph-cx78 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-99w6-3xph-cx78 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-99w6-3xph-cx78. 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-99w6-3xph-cx78 in your dependencies?
O3 detects GHSA-99w6-3xph-cx78 across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
