Published by the GitHub Advisory Database at 12 May 2026, 18:30 UTC. agentprime has not analysed this yet, so whether it affects any app is not known.

## Affected packages

- `snorkel` (PyPI): affected `<=0.10.0`; no fixed version yet

## Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

> Snorkel versions up to and including 0.10.0 are affected. The Trainer.load() method loads checkpoint files with torch.load() without weights_only=True, so a crafted model file can run arbitrary code when loaded. An attacker would need to supply that file to a victim who loads it through this method. No fix is listed.

## Check whether this affects you

A Match means an installed version is in the affected range above. Most don’t affect the app; agentprime hasn’t analysed this one yet.

- With the agentprime MCP server (<https://api.agentprime.io/mcp>), ask your agent to check the project: `check_lockfile` sends a lockfile, `check_packages` a list of installed packages, and both return the Matches and the upgrades that clear them. `get_advisory` returns this record. Setup: <https://agentprime.io/mcp.md>
- In a browser: <https://agentprime.io/check/> reads your lockfile in the browser, never uploading it.
- Whether it touches your code, with file and line: the Claude Code plugin, <https://agentprime.io/plugin.md>
- As JSON: <https://api.agentprime.io/v1/advisories/GHSA-78cp-f66x-qmh5>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
