SCA: security update for @workos/authkit-session (GHSA-vvvv-983w-r7pv)

medium Tenable Self-Hosted Container Security Plugin ID 441243

Description

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

- @workos/authkit-session is a toolkit for building WorkOS AuthKit framework integrations. Prior to 0.5.1,
an open redirect vulnerability exists in AuthService.handleCallback due to insufficient validation of the
returnPathname value derived from the OAuth state parameter. The state parameter is round-tripped through
the identity provider (IdP) and can be influenced by an attacker. The handleCallback function decodes and
returns returnPathname without enforcing restrictions on origin or scheme. As a result, attacker-
controlled values may be returned to the application. If this value is used directly in a redirect, it may
cause the user to be redirected to an external, attacker-controlled site. This vulnerability is fixed in
0.5.1. (CVE-2026-42565)

Solution

Update the @workos/authkit-session library and its related packages to version 0.5.1 or later.
