Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Dapr是Dapr开源的一个可移植、无服务器、事件驱动的运行时。 Dapr 1.3.0版本至1.15.14之前版本、1.16.0-rc.1版本至1.16.14之前版本和1.17.0-rc.1版本至1.17.5之前版本存在路径遍历漏洞，该漏洞源于使用保留URL字符和路径遍历序列绕过服务调用访问控制策略，可能导致ACL评估路径与目标应用接收路径不一致。

Vulnerability Title
Dapr: Service Invocation path traversal ACL bypass
Source: CVE Program / CVE List V5
Vulnerability Description
Dapr is a portable, event-driven, runtime for building distributed applications across cloud and edge. From versions 1.3.0 to before 1.15.14, 1.16.0-rc.1 to before 1.16.14, and 1.17.0-rc.1 to before 1.17.5, a vulnerability has been found in Dapr that allows bypassing access control policies for service invocation using reserved URL characters and path traversal sequences in method paths. The ACL normalized the method path independently from the dispatch layer, so the ACL evaluated one path while the target application received a different one. This issue has been patched in versions 1.15.14, 1.16.14, and 1.17.5.
