CVE-2026-37470Network attack vector

Credential theft via frameable login page

Published May 22, 2026 · Updated May 22, 2026

Clickjacking in ClipBucket v5 5.5.2 allows remote authenticated users to induce credential disclosure through a framed login page. The login endpoint returns responses without X-Frame-Options or a CSP frame-ancestors restriction, so another origin can embed it beneath deceptive controls. A victim must visit an attacker-controlled page and interact with the disguised frame; the grounded consequence is credential exposure, not code execution.
