The GoAhead WebsRedirect uses a static host buffer that has a limited length and can overflow.

MEDIUM 5.3EPSS 1.54%

Does this matter?

Lower severity and a low EPSS score (1.54%). Track it; it rarely justifies an emergency change on its own.

Description

Embedthis GoAhead before 5.0.1 mishandles redirected HTTP requests with a large Host header. The GoAhead WebsRedirect uses a static host buffer that has a limited length and can overflow. This can cause a copy of the Host header to fail, leaving that buffer uninitialized, which may leak uninitialized data in a response.
