CVE-2022-2653Network attack vector

Authenticated file disclosure via thumbnail path traversal

Published Aug 4, 2022 · Updated Aug 3, 2024

Path traversal in PLANKA before 1.5.1 allows remote authenticated users to read server-accessible files through a crafted thumbnail URL. The download-thumbnail action passes the free-form filename route parameter to path.join and fs.createReadStream without restricting the resolved path. A valid account and an existing attachment ID are required; successful requests disclose server files, including environment variables and database credentials.
