# Remediation Handoff: CVE-2026-82584

## Summary

NVD: Improper Neutralization of Escape, Meta, or Control Sequences vulnerability in ash-project igniter allows a malicious package publisher to forge the mix igniter.install confirmation prompt. NVD: mix igniter.install prints a confirmation panel (an anti-typosquatting safeguard) listing a package's hex metadata before adding it. NVD: The panel builder in Igniter.Project.Deps wrote publisher-controlled fields (meta.description, owner usernames, requirement names, version) to the terminal with only newlines stripped.
