CVE-2026-56305Public exploitNetwork attack vector

Account takeover via unverified password change

Published Jul 10, 2026 · Updated Jul 10, 2026

Authentication bypass in Capgo before 12.128.2 allows remote authenticated users to take over accounts through the password change endpoint. The endpoint accepts a new password based only on an active session and does not verify the current password or require reauthentication. Temporary session access is sufficient to replace the password, lock out the legitimate user, and retain control of the account.
