Unauthenticated phone-number disclosure via captcha bypass
Published Nov 15, 2024 · Updated Jul 5, 2026
Incorrect access control in KodCloud KodBox before 1.52.04 allows remote attackers to disclose registered users' phone numbers. The password-reset captcha accepts any supplied value, and endpoint responses distinguish phone numbers associated with registered accounts. No authentication is required; the resulting disclosure is limited to account-linked phone-number enumeration.
