# XWiki vulnerable to a reflected XSS via xredirect parameter in DeleteApplication Advisory record · `GHSA-7vpr-jm38-wr7w` - **Identifiers:** `GHSA-7vpr-jm38-wr7w` · `CVE-2025-66472` - **State:** Confirmed - **Severity:** CVSS 6.5 Medium - **Critical:** No - **Weakness (CWE):** [CWE-79](https://cwe.mitre.org/data/definitions/79.html) · [CWE-80](https://cwe.mitre.org/data/definitions/80.html) - **Tags:** [Cross-site scripting (XSS)](https://agentprime.io/advisories/tag/xss.md) - **Published:** 10 Dec 2025 - **Updated:** 11 Dec 2025 - **Reviewed by a person:** No Published by the GitHub Advisory Database at 10 Dec 2025, 15:46 UTC. agentprime has not analysed this yet, so whether it affects any app is not known. ## Affected packages - `org.xwiki.platform:xwiki-platform-flamingo-skin-resources` (Maven): affected `>=6.2-milestone-1, <16.10.10 || >=17.0.0-rc-1, <17.4.2`; fixed in `16.10.10`, `17.4.2` - `org.xwiki.platform:xwiki-platform-web-templates` (Maven): affected `>=6.2-milestone-1, <16.10.10 || >=17.0.0-rc-1, <17.4.2`; fixed in `16.10.10`, `17.4.2` ## Machine-written summary Summary written by Claude Haiku from the source advisory. Not reviewed by a person. > Two XWiki packages, xwiki-platform-flamingo-skin-resources and xwiki-platform-web-templates, are affected from 6.2-milestone-1 up to 16.10.10 and from 17.0.0-rc-1 up to 17.4.2. An attacker can send a victim a crafted link to a deletion confirmation page, and the attacker's script runs when the victim clicks "No". If the victim has admin or programming rights, the attacker can perform arbitrary actions, including remote code execution. Upgrade to 16.10.10 or 17.4.2. The source gives no other workaround beyond applying the patch manually to the templates in the WAR and restarting XWiki.

Once a person has reviewed it, this page will say what’s vulnerable, what has to be true for your app to be affected, and how to check. ## Severity and exploitation - 6.5 Medium, CVSS 4.0: `CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:N/SC:H/SI:H/SA:H`, from CNA (GitHub_M) - **CISA KEV:** Not listed. - **EPSS:** 0.0054, the 46th percentile, on 13 Nov 2026: FIRST’s estimate of the chance of exploitation in the next 30 days. ## Timeline - 31 Oct 2026, 15:09 UTC: First seen by agentprime - 31 Oct 2026, 15:09 UTC: [Confirmed by OSV](https://osv.dev/vulnerability/GHSA-7vpr-jm38-wr7w) ## Sources - [GitHub Advisory Database: GHSA-7vpr-jm38-wr7w](https://github.com/advisories/GHSA-7vpr-jm38-wr7w) - [OSV: GHSA-7vpr-jm38-wr7w](https://osv.dev/vulnerability/GHSA-7vpr-jm38-wr7w) - - - - - Facts on this page come from the GitHub Advisory Database (CC-BY 4.0), OSV and the other sources listed, as published. 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: .
