CVE-2024-3166Public exploitNetwork attack vector

Script execution via unsanitized embedded website content

Published Jun 6, 2024 · Updated Aug 1, 2024

Stored XSS in Mintplex Labs AnythingLLM before 1.4.2 allows remote attackers to execute JavaScript through embedded website content. The website-ingestion feature fetches page content into a workspace and renders attacker-controlled markup without neutralizing executable script. A victim must view the embedded content; desktop builds expose Node.js with context isolation disabled, allowing the script to execute host code.
