Doc Type: ---
Doc Text:
A flaw was found in Keycloak that prevents certain schemes in redirects, but permits them if a wildcard is appended to the token. This issue could allow an attacker to submit a specially crafted request leading to cross-site scripting (XSS) or further attacks. This flaw is the result of an incomplete fix for CVE-2020-10748.

Description Chess Hazlett 2023-11-14 18:51:39 UTC 
Keycloak prevents certain schemes in redirects, but permits them if a wildcard is appended to the token. This could permit an attacker to submit a specially crafted request leading to XSS or possibly further attacks.

Hello RH Team, 

CVE-2023-6291 seems to be assigned as well to this issue


CVE-2023-6291 keycloak: redirect_uri validation logic that allows for a bypass of otherwise explicitly allowed hosts (#57)
https://github.com/keycloak/keycloak/commit/15a21bf8e4fb71f006ba9caf25b9c9d1d152cd20

Same issue, and only 1 commit in 22.0.7.

Can you please update one of them ?

Thanks,

Hum after analysis, redirect_uri is linked to two issues, and you perfectly separated both issues. My bad for the comment.
