## Affected packages

- `org.apache.camel:camel-pqc` (Maven): affected `>=4.18.0, <4.18.3 || >=4.19.0, <4.21.0`; fixed in `4.18.3`, `4.21.0`

## Machine-written summary

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

> Apache Camel camel-pqc versions 4.18.0 to before 4.18.3 and 4.19.0 to before 4.21.0 are vulnerable to unsafe deserialization in the HashiCorp Vault and AWS Secrets Manager key-lifecycle managers. An attacker who can write to the configured Vault path or AWS secret could store a crafted serialized object that may lead to code execution in the application. Upgrade to camel-pqc 4.21.0, or 4.18.3 on the 4.18.x LTS stream; until then, restrict write access to the key backend to the application's own identity.

## 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-857v-xvh8-7hjc>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
