CVE-2026-45087— dalfox 访问控制错误漏洞

Dalfox: Unauthenticated Remote Code Execution via `found-action` in Dalfox Server Mode

Dalfox is a powerful open-source XSS scanner and utility focused on automation. Prior to 2.13.0, when dalfox is started in REST API server mode (dalfox server), the server binds to 0.0.0.0:6664 by default and requires no API key unless the operator explicitly passes --api-key. Because model.Options — including FoundAction and FoundActionShell — is deserialized directly from attacker-supplied JSON in POST /scan, and because dalfox.Initialize explicitly propagates those two fields into the final scan options without stripping them, any unauthenticated caller who can reach the server port can supply an arbitrary shell command that the dalfox process will execute on the host whenever a scan finding is triggered. This vulnerability is fixed in 2.13.0.

dalfox 访问控制错误漏洞

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之前版本存在访问控制错误漏洞，该漏洞源于REST API服务器模式默认绑定到0.0.0.0:6664且无需API密钥，且model.Options中的FoundAction和FoundActionShell字段直接从攻击者提供的JSON反序列化，可能导致未认证的调用者执行任意shell命令。
