GoDoxy is a reverse proxy and container orchestrator for self-hosters. Prior to version 0.27.5, the file content API endpoint at /api/v1/file/content is vulnerable to path traversal. The filename query parameter is passed directly to path.Join(common.ConfigBasePath, filename) where ConfigBasePath = "config" (a relative path). No sanitization or validation is applied beyond checking that the field is non-empty (binding:"required"). An authenticated attacker can use ../ sequences to read or write files outside the intended config/ directory, including TLS private keys, OAuth refresh tokens, and any file accessible to the container's UID. Version 0.27.5 fixes the issue.
