Stored XSS via MIME-sniffable API responses
Published Sep 20, 2024 · Updated Sep 20, 2024
Stored XSS in Lyft Confidant before 6.6.2 allows remote authenticated users to run scripts in another user's browser via crafted secret data. Credential and service API routes return attacker-controlled stored fields without forcing a JSON content type or blocking MIME sniffing, allowing browsers to interpret responses as HTML. The attacker must have permission to create credentials, and another user in the same instance must open the affected content.
