CVE-2024-41129
MEDIUMCVE-2024-41129 is a medium-severity (CVSS 4.4) CWE-532 vulnerability in ops. O3 Security confirms whether CVE-2024-41129 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
The ops library leaks secrets if `subprocess.CalledProcessError` happens with a `secret-*` CLI command
Blast Radius
opsReal-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
The ops library is a Python framework for developing and testing Kubernetes and machine charms. The issue here is that ops passes the secret content as one of the args via CLI. This issue may affect any of the charms that are using: Juju (>=3.0), Juju secrets and not correctly capturing and processing subprocess.CalledProcessError. This vulnerability is fixed in 2.15.0.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ops. 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 ops to 2.15.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-41129 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-2024-41129 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-2024-41129. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2024-41129 in your dependencies?
O3 detects CVE-2024-41129 across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
