Quick assessment

Affected
WSO2 WSO2 Identity Server
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

由于实现不完整，即使已启用 reCaptcha 选项，某些认证流程中仍未应用 reCaptcha。这一疏漏使得攻击者能够绕过预期的保护机制。 若暴力破解攻击成功，攻击者可通过系统性地尝试各种凭证组合，从而非法获取用户账户及敏感信息的访问权限。

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

Vulnerability Description
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.
