Description

Passbolt API before 4.6.2 allows HTML injection in a URL parameter, resulting in custom content being displayed when a user visits the crafted URL. Although the injected content is not executed as JavaScript due to Content Security Policy (CSP) restrictions, it may still impact the appearance and user interaction of the page.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for passbolt/passbolt_api, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update passbolt/passbolt_api to 4.6.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-33670 is resolved across your whole dependency graph.

  3. Workarounds

    Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.
