medium Tenable Self-Hosted Container Security Plugin ID 438686

Description

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

 - Tinyauth is an authentication and authorization server. Prior to 5.0.3, the OIDC token endpoint does not
 verify that the client exchanging an authorization code is the same client the code was issued to. A
 malicious OIDC client operator can exchange another client's authorization code using their own client
 credentials, obtaining tokens for users who never authorized their application. This violates RFC 6749
 Section 4.1.3. This vulnerability is fixed in 5.0.3. (CVE-2026-32245)

Solution

Update the github.com/steveiliop56/tinyauth library and its related packages to version 1.0.1-20260311144920-9eb2d33064b7 or later.
