CVE NOT AVAILABLE CWE-345  (opens in a new tab)

How to fix?

Upgrade stigmem-node to version 0.9.0a2 or higher.

Overview

stigmem-node is a Stigmem reference node — single-host production implementation

Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity due to improper validation in the peer-token timestamp process. An attacker can cause valid authentication tokens to be rejected by presenting tokens with timestamps that are incorrectly interpreted as expired, leading to disruption of authenticated federation flows and potential denial of service.

Workaround

This vulnerability can be mitigated by avoiding mixed peer-token minting paths and restricting federation use to tightly controlled peers.
