CVE-2025-59036 has a CVSS score of 5.5/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by CVE-2025-59036?

CVE-2025-59036 affects the following packages: infrahub-server (PyPI), infrahub-server (PyPI). Ecosystems affected: PyPI.

How do I fix CVE-2025-59036?

Update infrahub-server to 1.3.9 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-59036 is resolved across your whole dependency graph.

How do I detect CVE-2025-59036 in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for infrahub-server. 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.

How do I mitigate CVE-2025-59036 if there is no patch (or I can't update yet)?

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 does O3 Security protect against CVE-2025-59036?

O3 pinpoints whether CVE-2025-59036 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2025-59036 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-59036 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2025-59036?

CVE-2025-59036 has an EPSS (Exploit Prediction Scoring System) score of 0.2%, placing it in the 7th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2025-59036?

CVE-2025-59036 is classified as CWE-298 (CWE-298). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2025-59036 published, and has it been updated?

CVE-2025-59036 was published on September 9, 2025 and was last updated on April 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-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

Infrahub offers a central hub to manage data, templates, and playbooks. Prior to versiond 1.3.9 and 1.4.5, a bug in the authentication logic will cause API tokens that were deleted and/or expired to be considered valid. This means that any API token that is associated with an active user account can authenticate successfully. This issue is fixed in versions 1.3.9 and 1.4.5. As a workaround, users can delete or deactivate the account associated with a deleted API token to prevent that token from authenticating.
