# Craft CMS: Missing authorization check allows non-admin control panel users access to user registration metrics Advisory record · `GHSA-rvmm-v933-jgxq` - **Identifiers:** `GHSA-rvmm-v933-jgxq` · `CVE-2026-14794` · `PKSA-1412-5vdy-cd6w` - **State:** Confirmed - **Severity:** CVSS 5.3 Medium - **Critical:** No - **Weakness (CWE):** [CWE-266](https://cwe.mitre.org/data/definitions/266.html) · [CWE-285](https://cwe.mitre.org/data/definitions/285.html) · [CWE-862](https://cwe.mitre.org/data/definitions/862.html) - **Tags:** [Privilege escalation](https://agentprime.io/advisories/tag/privilege-escalation.md) · [Broken access control](https://agentprime.io/advisories/tag/access-control.md) - **Published:** 6 Aug 2026 - **Updated:** 31 Aug 2026 - **Reviewed by a person:** No Published by the GitHub Advisory Database at 6 Aug 2026, 21:42 UTC. agentprime has not analysed this yet, so whether it affects any app is not known. ## Affected packages - `craftcms/cms` (Packagist): affected `>=4.0.0-RC1, <4.18.1 || >=5.0.0-RC1, <5.10.3`; fixed in `4.18.1`, `5.10.3` ## Machine-written summary Summary written by Claude Haiku from the source advisory. Not reviewed by a person. > Craft CMS versions 4.0.0-RC1 up to (but not including) 4.18.1, and 5.0.0-RC1 up to (but not including) 5.10.3, are affected. A control panel user who has only the accessCp permission, and no viewUsers permission, can send a request to the charts endpoint that returns aggregate user registration counts over a chosen time period, either site-wide or for a given user group, because the action lacks the viewUsers permission check. No personal data such as names, emails, or passwords is exposed, only counts and timestamps. The fix is to upgrade to Craft CMS 4.18.1 or 5.10.3.

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: .
