Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Cloudreve v4 versions before 4.0.0-20260626022735-332a9d800205 and Cloudreve v3 up to and including 3.0.0-20250225100611-da4e44b77af4 are affected. An attacker holding an admin-authorized OAuth token with only the Admin.Read scope can call the node test endpoints, which make the server send requests to attacker-supplied URLs, enabling blind SSRF and internal service probing. Upgrade Cloudreve v4 to 4.0.0-20260626022735-332a9d800205 or later. No fix is listed for v3.
