# XWiki Platform: Remote code execution as guest via DatabaseSearch Advisory record · `GHSA-2858-8cfx-69m9` - **Identifiers:** `GHSA-2858-8cfx-69m9` · `CVE-2024-31982` - **State:** Confirmed - **Severity:** CVSS 10.0 Critical - **Critical:** Yes: CVSS 9+, CVSS 7+ and EPSS - **Weakness (CWE):** [CWE-94](https://cwe.mitre.org/data/definitions/94.html) · [CWE-95](https://cwe.mitre.org/data/definitions/95.html) - **Tags:** [Code injection](https://agentprime.io/advisories/tag/code-injection.md) - **Published:** 10 Apr 2024 - **Updated:** 10 Sept 2026 - **Reviewed by a person:** No Published by the GitHub Advisory Database at 10 Apr 2024, 17:12 UTC. agentprime has not analysed this yet, so whether it affects any app is not known. ## Critical Critical, because: - CVSS score 10.0: 9.0 or more. - CVSS score 10.0 (7.0 or more) and EPSS 0.35 (0.1 or more): a high score and a real chance of exploitation in the next 30 days. How we decide what’s critical: ## Affected packages - `org.xwiki.platform:xwiki-platform-search-ui` (Maven): affected `>=2.4-milestone-1, <14.10.20 || >=15.0-rc-1, <15.5.4 || >=15.6-rc-1, <15.10-rc-1`; fixed in `14.10.20`, `15.5.4`, `15.10-rc-1` ## Machine-written summary Summary written by Claude Haiku from the source advisory. Not reviewed by a person. > XWiki Platform's xwiki-platform-search-ui package is vulnerable to remote code execution through the database search text in versions from 2.4-milestone-1 before 14.10.20, from 15.0-rc-1 before 15.5.4, and from 15.6-rc-1 before 15.10-rc-1. An attacker needs no account, since the database search is accessible to any visitor by default, and can run code on the whole XWiki installation. Upgrade to 14.10.20, 15.5.4, 15.10-rc-1 or later. Alternatively, if database search is not used, the Main.DatabaseSearch page can be deleted. Written 2 Nov 2026. ## Not analysed yet We haven’t published our analysis of this Advisory yet. 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 - 10.0 Critical, CVSS 3.1: `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H`, from CNA (GitHub_M) - **CISA KEV:** Not listed. - **EPSS:** 0.35, the 98th percentile, on 14 Nov 2026: FIRST’s estimate of the chance of exploitation in the next 30 days. ## Timeline - 31 Oct 2026, 14:17 UTC: First seen by agentprime - 31 Oct 2026, 14:17 UTC: [Confirmed by OSV](https://osv.dev/vulnerability/GHSA-2858-8cfx-69m9) ## Sources - [GitHub Advisory Database: GHSA-2858-8cfx-69m9](https://github.com/advisories/GHSA-2858-8cfx-69m9) - [OSV: GHSA-2858-8cfx-69m9](https://osv.dev/vulnerability/GHSA-2858-8cfx-69m9) - - - - - - - - - - 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: .
