CVE-2026-55497

Summary (CVE-2026-55497): Cloudreve before 4.17.0 is vulnerable to an unbounded memory allocation during image decoding. The built‑in thumbnail and avatar decoders only cap the compressed file size; they do not limit decoded pixel dimensions for PNG/JPEG/GIF, enabling an authenticated user to sub...

CVE-2026-55497 Cloudreve: Server crash through image decompression/pixel bomb in thumbnail & avatar decoding (DoS)

Cloudreve is a self-hosted file management and sharing system. Prior to 4.17.0, the built-in thumbnail and avatar image decoders limit compressed file size but do not limit decoded pixel dimensions, allowing an authenticated user to submit a small PNG, JPEG, or GIF that triggers an unbounded...

GHSA-G9J2-8W95-3VWV Cloudreve: Denial of Service - Image decompression / pixel bomb in thumbnail & avatar decoding crashes the server

Summary Cloudreve's built-in image processor decodes user-supplied images with Go's standard-library decoders image/png, image/jpeg, image/gif and guards only the compressed file size — never the decoded pixel dimensions. Go's decoders allocate a pixel buffer sized bytesPerPixel × width × height...
