CVE-2026-86041 Details

Description

ezBookkeeping is an open source, self-hosted personal finance application. From 0.10.0 until 1.6.0, ezBookkeeping constructs its Gin router with gin.New() without configuring SetTrustedProxies, causing c.ClientIP() to trust a spoofed X-Forwarded-For value. An unauthenticated remote attacker can supply an allowlisted address to bypass the mcp_allowed_remote_ips or api_token_allowed_remote_ips gate. A valid MCP or API token remains required for protected actions. When such actions occur, the same spoofed value is stored in Transaction.CreatedIp and the request log, attributing activity to the trusted host instead of the attacker. This issue is fixed in version 1.6.0.
