Prior to 0.11.10, the apps/readest-app/src/pages/api/storage/upload.ts route constructed an object key from the authenticated user&#39;s identifier and a client-controlled fileName without rejecting path separators or parent-directory traversal. In the R2 backend, apps/readest-app/src/utils/r2.ts placed that key into a new Request URL before signing it, and URL normalization collapsed parent-directory components so the resulting presigned PUT could escape the caller&#39;s namespace. An authenticated attacker who knew a target user identifier and book hash could overwrite or poison that user&#39;s stored book object and corrupt the associated file_key metadata; the exact cross-tenant escape was verified for the R2 backend. This issue is fixed in version 0.11.10.</p> <p>Readest is a modern, feature-rich ebook reader designed for seamless cross-platform access and an intuitive reading experience.
