SCA: security update for doorkeeper-openid_connect (GHSA-m6vc-f87m-cc2h)

medium Tenable Self-Hosted Container Security Plugin ID 442639

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Doorkeeper is an OAuth 2 provider for Ruby on Rails. In version 1.9.0, an attacker who knows only a
 dynamically registered client's client_id, which is public information, can authenticate as that client at
 the token endpoint and obtain an access token without providing its client_secret. This occurs because the
 Dynamic Client Registration feature creates applications with confidential: false hard-coded, even though
 the registration response returns a client_secret and advertises support for the client_secret_basic and
 client_secret_post authentication methods; since Doorkeeper treats a blank or missing secret as valid for
 non-confidential (public) clients, the secret is never verified. Only projects that have explicitly
 enabled Dynamic Client Registration, which is disabled by default, are affected. This issue is fixed in
 version 1.10.0. (CVE-2026-44476)

Solution

Update the doorkeeper-openid_connect library and its related packages to version 1.10.0 or later.
