Published by the GitHub Advisory Database at 25 Jun 2026, 18:34 UTC. agentprime has not analysed this yet, so whether it affects any app is not known.

## Affected packages

- `amazon-braket-sdk` (PyPI): affected `>=1.10.0, <1.117.0`; fixed in `1.117.0`

## Machine-written summary

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

> The amazon-braket-sdk package, versions 1.10.0 up to but not including 1.117.0, is vulnerable to insecure deserialization. An attacker with write access to the S3 bucket that stores a Braket job's output can alter the results file so the SDK calls pickle.loads() on attacker-supplied data when the victim retrieves job results, allowing arbitrary code execution with the victim's permissions. Upgrade to amazon-braket-sdk 1.117.0 or later. As a workaround, restrict s3:PutObject permissions on job output buckets to trusted principals only.

## 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-g697-2xrc-gc46>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
