GHSA-37q5-v5qm-c9v8 has a CVSS score of 3.4/10, rated LOW. Review your exposure and patch according to your risk tolerance.

Which packages are affected by GHSA-37q5-v5qm-c9v8?

GHSA-37q5-v5qm-c9v8 affects the following packages: transformers (PyPI). Ecosystems affected: PyPI.

How do I fix GHSA-37q5-v5qm-c9v8?

Update transformers to 4.38.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-37q5-v5qm-c9v8 is resolved across your whole dependency graph.

How do I detect GHSA-37q5-v5qm-c9v8 in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for transformers. 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-37q5-v5qm-c9v8 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-37q5-v5qm-c9v8?

O3 pinpoints whether GHSA-37q5-v5qm-c9v8 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-37q5-v5qm-c9v8 actively exploited in the wild?

No public exploit code has been indexed for GHSA-37q5-v5qm-c9v8 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-37q5-v5qm-c9v8?

GHSA-37q5-v5qm-c9v8 has an EPSS (Exploit Prediction Scoring System) score of 2.1%, placing it in the 79th 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 GHSA-37q5-v5qm-c9v8?

GHSA-37q5-v5qm-c9v8 is classified as Deserialization of Untrusted Data (CWE-502). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was GHSA-37q5-v5qm-c9v8 published, and has it been updated?

GHSA-37q5-v5qm-c9v8 was published on April 10, 2024 and was last updated on April 10, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

The huggingface/transformers library is vulnerable to arbitrary code execution through deserialization of untrusted data within the load_repo_checkpoint() function of the TFPreTrainedModel() class. Attackers can execute arbitrary code and commands by crafting a malicious serialized payload, exploiting the use of pickle.load() on data from potentially untrusted sources. This vulnerability allows for remote code execution (RCE) by deceiving victims into loading a seemingly harmless checkpoint during a normal training process, thereby enabling attackers to execute arbitrary code on the targeted machine.
