CVE-2026-120426: OpenCSG CSGHub through v2.6.0-ce Unauthenticated Private Repository File Read via Resolve Route

OpenCSG CSGHub through v2.6.0-ce contains an authorization bypass vulnerability in the unauthenticated file resolve route that allows remote attackers to read private repository files. Attackers can inject a percent-encoded currentuser parameter into the file path, which the portal forwards with its server API key, to read files in private model, code or space repositories.
