Summary

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.

Risk Assessment

An attacker could exploit this vulnerability to modify enterprise profiles, potentially leading to defacement, phishing, and loss of customer trust.

Recommendation

Update 53AIHub to a version later than 0.5.3 if available, or fix the UpdateEnterprise logic to always enforce authentication and authorization checks.
