How severe is GHSA-v8vj-cv27-hjv8?

GHSA-v8vj-cv27-hjv8 has a CVSS score of 9.8/10, rated CRITICAL. Immediate patching is strongly recommended.

Which packages are affected by GHSA-v8vj-cv27-hjv8?

GHSA-v8vj-cv27-hjv8 affects the following packages: langchain-experimental (PyPI). Ecosystems affected: PyPI.

How do I fix GHSA-v8vj-cv27-hjv8?

Update langchain-experimental to 0.0.52 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-v8vj-cv27-hjv8 is resolved across your whole dependency graph.

How do I detect GHSA-v8vj-cv27-hjv8 in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for langchain-experimental. 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-v8vj-cv27-hjv8 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-v8vj-cv27-hjv8?

O3 pinpoints whether GHSA-v8vj-cv27-hjv8 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-v8vj-cv27-hjv8 actively exploited in the wild?

No public exploit code has been indexed for GHSA-v8vj-cv27-hjv8 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-v8vj-cv27-hjv8?

GHSA-v8vj-cv27-hjv8 has an EPSS (Exploit Prediction Scoring System) score of 0.8%, placing it in the 51th 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-v8vj-cv27-hjv8?

GHSA-v8vj-cv27-hjv8 is classified as CWE-749 (CWE-749). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-v8vj-cv27-hjv8 published, and has it been updated?

GHSA-v8vj-cv27-hjv8 was published on February 26, 2024 and was last updated on August 6, 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

langchain_experimental (aka LangChain Experimental) before 0.0.52, part of LangChain before 0.1.8, allows an attacker to bypass the CVE-2023-44467 fix and execute arbitrary code via the __import__, __subclasses__, __builtins__, __globals__, __getattribute__, __bases__, __mro__, or __base__ attribute in Python code. These are not prohibited by pal_chain/base.py.
