SCA: security update for github.com/pomerium/pomerium (GHSA-rrqr-7w59-637v)

medium Tenable Self-Hosted Container Security Plugin ID 418910

Description

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

 - Pomerium is an identity and context-aware access proxy. Prior to version 0.26.1, the Pomerium user info
 page (at `/.pomerium`) unintentionally included serialized OAuth2 access and ID tokens from the logged-in
 user's session. These tokens are not intended to be exposed to end users. This issue may be more severe in
 the presence of a cross-site scripting vulnerability in an upstream application proxied through Pomerium.
 If an attacker could insert a malicious script onto a web page proxied through Pomerium, that script could
 access these tokens by making a request to the `/.pomerium` endpoint. Upstream applications that
 authenticate only the ID token may be vulnerable to user impersonation using a token obtained in this
 manner. Note that an OAuth2 access token or ID token by itself is not sufficient to hijack a user's
 Pomerium session. Upstream applications should not be vulnerable to user impersonation via these tokens
 provided the application verifies the Pomerium JWT for each request, the connection between Pomerium and
 the application is secured by mTLS, or the connection between Pomerium and the application is otherwise
 secured at the network layer. The issue is patched in Pomerium v0.26.1. No known workarounds are
 available. (CVE-2024-39315)
