SCA: security update for github.com/oauth2-proxy/oauth2-proxy/v7 (GHSA-f24x-5g9q-753f)

low Tenable Self-Hosted Container Security Plugin ID 440402

Description

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

 - OAuth2 Proxy is a reverse proxy that provides authentication using OAuth2 providers. A regression
 introduced in 7.11.0 prevents OAuth2 Proxy from clearing the session cookie when rendering the sign-in
 page. In deployments that rely on the sign-in page as part of their logout flow, a user may be shown the
 sign-in page while the existing session cookie remains valid, meaning the browser session is not actually
 logged out. On shared workstations or devices, a subsequent user could continue to use the previous user's
 authenticated session. Deployments that use a dedicated logout/sign-out endpoint to terminate sessions are
 not affected. This issue is fixed in 7.15.2 (CVE-2026-34454)

Solution

Update the github.com/oauth2-proxy/oauth2-proxy/v7 library and its related packages to version 7.15.2 or later.
