Published by the GitHub Advisory Database at 25 Jul 2024, 14:15 UTC. agentprime has not analysed this yet, so whether it affects any app is not known.

## Affected packages

- `org.openidentityplatform.openam:openam-oauth2` (Maven): affected `<15.0.4`; fixed in `15.0.4`

## Machine-written summary

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

> OpenAM's openam-oauth2 Maven package (Maven org.openidentityplatform.openam:openam-oauth2) is affected in versions before 15.0.4. The custom login URL template setting in RealmOAuth2ProviderSettings is not restricted, so user-supplied input is processed as a FreeMarker template, enabling template injection. The source gives few details on the required access or the resulting impact. Upgrade to version 15.0.4, which is the listed fixed version.

## 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-7726-43hg-m23v>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
