Which packages are affected by GHSA-747f-ww56-4q4h?

GHSA-747f-ww56-4q4h affects the following packages: kedro (PyPI). Ecosystems affected: PyPI.

How do I fix GHSA-747f-ww56-4q4h?

Update kedro to 0.19.9 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-747f-ww56-4q4h is resolved across your whole dependency graph.

How do I detect GHSA-747f-ww56-4q4h in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for kedro. 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 GHSA-747f-ww56-4q4h 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 GHSA-747f-ww56-4q4h?

O3 pinpoints whether GHSA-747f-ww56-4q4h 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 GHSA-747f-ww56-4q4h actively exploited in the wild?

No public exploit code has been indexed for GHSA-747f-ww56-4q4h 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 GHSA-747f-ww56-4q4h?

GHSA-747f-ww56-4q4h has an EPSS (Exploit Prediction Scoring System) score of 1.0%, placing it in the 60th 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.

When was GHSA-747f-ww56-4q4h published, and has it been updated?

GHSA-747f-ww56-4q4h was published on March 20, 2025 and was last updated on March 21, 2025. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

A Remote Code Execution (RCE) vulnerability has been identified in the Kedro ShelveStore class (version 0.19.8). This vulnerability allows an attacker to execute arbitrary Python code via deserialization of malicious payloads, potentially leading to a full system compromise. The ShelveStore class uses Python's shelve module to manage session data, which relies on pickle for serialization. Crafting a malicious payload and storing it in the shelve file can lead to RCE when the payload is deserialized.
