CVE-2024-5563 PUBLISHED

Incomplete reCaptcha Implementation in Authentication Flows in WSO2 Identity Server Allows Brute Force Attacks

Assigner: WSO2
Reserved: 31.05.2024 Published: 21.10.2026 Updated: 21.10.2026

Due to an incomplete implementation, reCaptcha is not applied to certain authentication flows even when the reCaptcha option is enabled. This oversight permits attackers to bypass the intended protection mechanism.

Brute force attacks, if successful, can lead to unauthorized access to user accounts and sensitive information by systematically attempting various credential combinations.
