GHSA-gpx5-7xm4-229w
HIGHGHSA-gpx5-7xm4-229w is a high-severity (CVSS 8.8) remote code execution vulnerability in snorkel. O3 Security confirms whether GHSA-gpx5-7xm4-229w is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Snorkel MultitaskClassifier.load uses an unsafe torch.load
Real-World Exposure
snorkelReal-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 snorkel library thru v0.10.0 contains an insecure deserialization vulnerability (CWE-502) in the MultitaskClassifier.load() method of the MultitaskClassifier class. The method loads model weight files using torch.load() without enabling the security-restrictive weights_only=True parameter. This default behavior allows the deserialization of arbitrary Python objects via the Pickle module. A remote attacker can exploit this by providing a maliciously crafted model file, leading to arbitrary code execution on the victim's system when the file is loaded via the vulnerable method.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for snorkel. 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.
Remediation status
No patched version of snorkel has shipped for GHSA-gpx5-7xm4-229w yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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 GHSA-gpx5-7xm4-229w 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 GHSA-gpx5-7xm4-229w. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
