53AIHub through 0.5.3 contains a missing authentication vulnerability that allows unauthenticated attackers to overwrite any enterprise's profile by sending PUT requests to /api/enterprises/:id. Because UpdateEnterprise only enforces checks when IS_SAAS is true, attackers can enumerate sequential enterprise IDs and overwrite logos, display names and branding for defacement and phishing.
