Name of the Vulnerable Software and Affected Versions
better-auth versions 0.0.3 through 1.1.15
Description
A reflected cross-site scripting (XSS) issue exists on the '/api/auth/error' endpoint. The application reflects the value of the
error URL parameter as HTML without proper neutralization, allowing an attacker to execute arbitrary JavaScript in the user's browser by inducing them to visit a specially-crafted URL.Recommendations
Update to version 1.1.16.
As a temporary workaround, restrict access to the '/api/auth/error' endpoint or avoid using the
error parameter until the update is applied.Exploitability
