Published by the GitHub Advisory Database at 5 Jan 2026, 15:32 UTC. agentprime has not analysed this yet, so whether it affects any app is not known.

## Affected packages

- `org.apache.sis.core:sis-metadata` (Maven): affected `>=0.4, <1.6`; fixed in `1.6`

## Machine-written summary

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

> Apache SIS (Maven package org.apache.sis.core:sis-metadata) versions 0.4 through 1.5 are vulnerable to XML external entity injection when parsing GeoTIFF files with DGIWG GEO_METADATA tags, ISO 19115 XML metadata, GML coordinate reference systems, or GPX files. An attacker who can supply such a file can read the contents of local files on the server. Upgrade to version 1.6, which fixes the issue. As a workaround, set the javax.xml.accessExternalDTD system property to restrict external protocols when launching Java.

## 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-jqmr-2pg9-vfx7>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
