Summary
WSO2 API Manager from 4.1.0 before 4.1.0.153, from 4.2.0 before 4.2.0.105, and from 4.3.0 before 4.3.0.20 fails to validate the callback URL parameter. An unauthenticated remote attacker can redirect users to attacker-controlled web pages, which can be combined with social engineering to trick users into opening malicious links for phishing (CWE-601).

Description from the CNA
The callback URL parameter in WSO2 API Manager fails to validate user-supplied input, allowing it to be controlled by malicious actors. Exploitation of this vulnerability could lead to users being redirected to attacker-controlled web pages. This can be used in conjunction with social engineering techniques to trick users into interacting with malicious links, potentially resulting in phishing attacks aimed at acquiring sensitive information or causing other harm.
