CVE-2026-55497

6.5 mediumEPSS 0.5%

Medium (6.5). EPSS 0.5% chance of exploitation in the next 30 days. Fixed in github.com/cloudreve/Cloudreve/v4 4.0.0-20260613024411-3607f79bb44c.

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 allocation and terminates the Cloudreve process through fatal out-of-memory behavior. This issue is fixed in version 4.17.0.
