CVE-2026-54562

6.5 mediumEPSS 0.4%

Medium (6.5). EPSS 0.4% chance of exploitation in the next 30 days. Fixed in github.com/cloudreve/Cloudreve/v4 4.0.0-20260606025411-aaebf317a78f.

Cloudreve is a self-hosted file management and sharing system. Prior to 4.16.1, Cloudreve's remote download workflow accepts user-supplied URLs at POST /api/v4/workflow/download and passes them to the configured downloader without blocking loopback, localhost, IPv6 localhost, or redirect-to-loopback targets, allowing a non-admin user with remote download permission to fetch internal-only URLs and read the response after it is imported into the user's own files. This issue is fixed in version 4.16.1.
