CVE-2024-45036Network attack vector

Token disclosure via untrusted artifact endpoint

Published Aug 26, 2024 · Updated Aug 27, 2024

Improper authentication in Shopify Tophat before 1.10.0 allows remote attackers to steal an app token through a malicious Tophat URL. The API artifact-retrieval flow reads TOPHAT_APP_TOKEN from ~/.tophatrc and sends it to the supplied server without validating that server as trusted. Opening the crafted URL is required, after which the exposed token grants access to otherwise private mobile build artifacts.
