## Affected packages

- `tensorflow` (PyPI): affected `<2.8.4 || >=2.9.0, <2.9.3 || >=2.10.0, <2.10.1`; fixed in `2.8.4`, `2.9.3`, `2.10.1`
- `tensorflow-cpu` (PyPI): affected `<2.8.4 || >=2.9.0, <2.9.3 || >=2.10.0, <2.10.1`; fixed in `2.8.4`, `2.9.3`, `2.10.1`
- `tensorflow-gpu` (PyPI): affected `<2.8.4 || >=2.9.0, <2.9.3 || >=2.10.0, <2.10.1`; fixed in `2.8.4`, `2.9.3`, `2.10.1`

## Machine-written summary

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

> The tensorflow, tensorflow-cpu, and tensorflow-gpu packages are affected in versions before 2.8.4, from 2.9.0 before 2.9.3, and from 2.10.0 before 2.10.1. When the broadcast helper BCast::ToShape receives input larger than an int32, it crashes the process, even though it should handle int64 values. An attacker who can pass large input to a call such as tf.experimental.numpy.outer can trigger this denial of service. Upgrade to 2.8.4, 2.9.3, 2.10.1, or later.

## 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-h246-cgh4-7475>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
