## Affected packages

- `org.hibernate.validator:hibernate-validator` (Maven): affected `<6.2.0.Final`; fixed in `6.2.0.Final`
- `org.hibernate:hibernate-validator` (Maven): affected `<6.2.0.Final`; fixed in `6.2.0.Final`

## Machine-written summary

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

> hibernate-validator versions before 6.2.0.Final are affected. The SafeHtmlValidator's isValid method can be bypassed by omitting the closing less-than character of a tag, so browsers may render the resulting invalid HTML, allowing HTML injection or cross-site scripting. Upgrade to 6.2.0.Final 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-x83m-pf6f-pf9g>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
