# XWiki missing authorization when accessing the wiki level attachments list and metadata via REST API Advisory record · `GHSA-r5cr-xm48-97xp` - **Identifiers:** `GHSA-r5cr-xm48-97xp` · `CVE-2025-46554` - **State:** Confirmed - **Severity:** CVSS 5.3 Medium - **Critical:** No - **Weakness (CWE):** [CWE-862](https://cwe.mitre.org/data/definitions/862.html) - **Tags:** [Broken access control](https://agentprime.io/advisories/tag/access-control.md) - **Published:** 30 Apr 2025 - **Updated:** 5 May 2025 - **Reviewed by a person:** No Published by the GitHub Advisory Database at 30 Apr 2025, 16:49 UTC. agentprime has not analysed this yet, so whether it affects any app is not known. ## Affected packages - `org.xwiki.platform:xwiki-platform-rest-server` (Maven): affected `>=1.8.1, <14.10.22 || >=15.0-rc-1, <15.10.12 || >=16.0.0-rc-1, <16.4.3 || >=16.5.0-rc-1, <16.7.0`; fixed in `14.10.22`, `15.10.12`, `16.4.3`, `16.7.0` ## Machine-written summary Summary written by Claude Haiku from the source advisory. Not reviewed by a person. > XWiki's xwiki-platform-rest-server (Maven org.xwiki.platform:xwiki-platform-rest-server) is affected in versions 1.8.1 up to 14.10.22, 15.0-rc-1 up to 15.10.12, 16.0.0-rc-1 up to 16.4.3, and 16.5.0-rc-1 up to 16.7.0. The REST endpoint for wiki attachments does not filter results by user rights, so an unauthenticated user can list attachments and read their metadata even on a private wiki. Upgrade to 14.10.22, 15.10.12, 16.4.3, or 16.7.0. No workaround other than upgrading is listed. Written 7 Nov 2026. ## Not analysed yet We haven’t published our analysis of this Advisory yet.

We don’t reproduce full advisory descriptions, which can contain exploit code. ## 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 (), 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: - In a browser: reads your lockfile in the browser, never uploading it. - Whether it touches your code, with file and line: the Claude Code plugin, - As JSON: , or `POST https://api.agentprime.io/v1/match` with your packages () --- The web page: .
