CVE-2026-45090— dalfox 安全漏洞

Dalfox: Unauthenticated Remote DoS via Closed-Channel Write in `ParameterAnalysis` (server mode)

Dalfox is a powerful open-source XSS scanner and utility focused on automation. Prior to 2.13.0, ParameterAnalysis in pkg/scanning/parameterAnalysis.go runs two sequential worker stages that both write to the same results channel. The channel is correctly closed after the first stage completes (close(results) at line 438), but the second stage — which processes POST-body parameters (dp) — is then launched with the same already-closed channel as its output. When a scanned parameter is reflected, processParams executes results <- paramResult on the closed channel, triggering a Go runtime panic that crashes the entire dalfox process. In server mode, the crash is remotely triggerable by any unauthenticated caller who can reach the REST API, because the default configuration has no API key and the second stage activates whenever options.Data != "" (i.e., the attacker supplies the data field) and the target reflects at least one parameter. This vulnerability is fixed in 2.13.0.

dalfox 安全漏洞

dalfox是HAHWUL个人开发者的一款自动化跨站脚本扫描工具。 Dalfox 2.13.0之前版本存在安全漏洞，该漏洞源于ParameterAnalysis中两个工作阶段写入同一已关闭的results通道，可能导致Go运行时恐慌并崩溃整个dalfox进程。
