Description
lorawan-stack is an open source LoRaWAN network server. Prior to version 3.24.1, an open redirect exists on the login page of the lorawan stack server, allowing an attacker to supply a user controlled redirect upon sign in. This issue may allows malicious actors to phish users, as users assume they were redirected to the homepage on login. Version 3.24.1 contains a fix.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for go.thethings.network/lorawan-stack/v3, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update go.thethings.network/lorawan-stack/v3 to 3.24.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-26494 is resolved across your whole dependency graph.
Workarounds
Stop reflecting attacker-controlled destinations: resolve every redirect target against an allowlist of paths or hosts you own, prefer a server-side key over a full URL in the request, and reject absolute URLs entirely where the flow only ever needs a relative one.
