Description

Summary

An attacker can use the next parameter on the login page to redirect a victim to a malicious page, while masking this using a legit-looking app.khoj.dev url. For example, https://app.khoj.dev/login?next=//example.com will redirect to the https://example.com page.

Details

The problem seems to be in this method: https://github.com/khoj-ai/khoj/blob/2667ef45449eb408ce1d7c393be04845be31e15f/src/khoj/routers/auth.py#L95

PoC

Open the https://app.khoj.dev/login?next=//example.com url in a Gecko-based browser (Firefox).

Impact

The impact is low, and this could only be used in phishing attempts, but it's still a problem nonetheless.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for khoj-assistant. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update khoj-assistant to 1.14.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-564j-v29w-rqr6 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether GHSA-564j-v29w-rqr6 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-564j-v29w-rqr6. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
