An OAuth client that has been authorized by an administrator with only the Admin.Read scope can therefore submit attacker-controlled node definitions and cause the Cloudreve server to issue outbound requests to arbitrary URLs, enabling blind server-side request forgery, internal service probing, and delivery of signed Cloudreve slave-style requests to attacker-chosen endpoints.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-101048)\n\nAffected packages:\n\n- `github.com/cloudreve/Cloudreve/v4 < 4.0.0-20260626022735-332a9d800205`\n- `github.com/cloudreve/Cloudreve/v3 <= 3.0.0-20250225100611-da4e44b77af4`\n\nPatched in:\n\n- `github.com/cloudreve/Cloudreve/v4 4.0.0-20260626022735-332a9d800205`\n\nSource: https://osv.dev/vulnerability/GHSA-v6w6-358x-2433","depth":"twilight","depthScore":42,"depthScoreParts":{"impact":29.7,"likelihood":0,"exploitation":12,"ransomware":0},"changes":[{"seq":213739,"id":"CVE-2026-101048","ts":1790784761309,"field":"exploit_available","old":"false","new":"true"}]}
