Version        :
CVE ID         : CVE-2021-39191 CVE-2022-23527
Debian Bug     : 993648 1026444

Open Redirect vulnerabilities were found in libapache2-mod-auth-openidc,
OpenID Connect Relying Party implementation for Apache, which could lead
to information disclosure via phishing attacks.


    The 3rd-party init SSO functionality of mod_auth_openidc was
    reported to be vulnerable to an open redirect attack by supplying a
    crafted URL in the target_link_uri parameter.


    When providing a logout parameter to the redirect URI,
    mod_auth_openidc failed to properly check for URLs starting with
    "/\t", leading to an open redirect.

For Debian 10 buster, these problems have been fixed in version

We recommend that you upgrade your libapache2-mod-auth-openidc packages.
