Vulnerability in Directus (CVE-2026-35408)
Summary
Vulnerability in Directus (CVE-2026-35408). Confidential information can be exposed externally. Mitigation: upgrade to 11.17.0 or later.
Original description
The description as published by the source.
Directus is a real-time API and App dashboard for managing SQL database content. Prior to 11.17.0, Directus's Single Sign-On (SSO) login pages lacked a Cross-Origin-Opener-Policy (COOP) HTTP response header. Without this header, a malicious cross-origin window that opens the Directus login page retains the ability to access and manipulate the window object of that page. An attacker can exploit this to intercept and redirect the OAuth authorization flow to an attacker-controlled OAuth client, causing the victim to unknowingly grant access to their authentication provider account (e.g. Google, Discord). This vulnerability is fixed in 11.17.0.
