Package        : ruby-doorkeeper
Version        : 4.4.2-1+deb10u1
CVE ID         : CVE-2023-34246
Debian Bug     : 1038950

It was discovered that there was an issue in ruby-doorkeeper, a
OAuth2 provider for Ruby on Rails applications. Doorkeeper
automatically processed authorization requests without user consent
for public clients that have been previously approved, but public
clients are inherently vulnerable to impersonation as their identity
cannot be assured.

For Debian 10 buster, this problem has been fixed in version
4.4.2-1+deb10u1.

We recommend that you upgrade your ruby-doorkeeper packages.

For the detailed security status of ruby-doorkeeper please refer to
its security tracker page at:
