Hello, Our static analyzer found a following potential NPE. We have checked the feasibility of this execution trace. It is necessary to defend this vulnerability to improve the code quality. This issue has a similar bug trace as the one in #8194 1. Return **null** to caller https://github.com/apache/dubbo/blob/f26ba91b67f642148a10d3b197502e29928b77bf/dubbo-common/src/main/java/org/apache/dubbo/common/utils/UrlUtils.java#L69 2. Function **parseURL** executes and returns https://github.com/apache/dubbo/blob/f26ba91b67f642148a10d3b197502e29928b77bf/dubbo-common/src/main/java/org/apache/dubbo/common/utils/UrlUtils.java#L174 3. Function **add** executes and **registries** can contains **null** value https://github.com/apache/dubbo/blob/f26ba91b67f642148a10d3b197502e29928b77bf/dubbo-common/src/main/java/org/apache/dubbo/common/utils/UrlUtils.java#L174 4. Program reaches the return point, and **registries** is the return value, which contains **null** value https://github.com/apache/dubbo/blob/f26ba91b67f642148a10d3b197502e29928b77bf/dubbo-common/src/main/java/org/apache/dubbo/common/utils/UrlUtils.java#L176 5. Function **parseURLs** executes and returns https://github.com/apache/dubbo/blob/f26ba91b67f642148a10d3b197502e29928b77bf/dubbo-config/dubbo-config-api/src/main/java/org/apache/dubbo/config/utils/ConfigValidationUtils.java#L206 6. Function **next** executes and returns **null** value https://github.com/apache/dubbo/blob/f26ba91b67f642148a10d3b197502e29928b77bf/dubbo-config/dubbo-config-api/src/main/java/org/apache/dubbo/config/utils/ConfigValidationUtils.java#L208 7. The return value of function **next** is passed as the this pointer to function **getProtocol** (the return value of function **next** can be **null**), which will leak to null pointer dereference https://github.com/apache/dubbo/blob/f26ba91b67f642148a10d3b197502e29928b77bf/dubbo-config/dubbo-config-api/src/main/java/org/apache/dubbo/config/utils/ConfigValidationUtils.java#L211 Commit: f26ba91b67f642148a10d3b197502e29928b77bf ContainerAnalyzer -- This is an automated message from the Apache Git Service.
