Aias00 opened a new issue, #6702:
URL: https://github.com/apache/shenyu/issues/6702
- severity: Medium
- files:
`shenyu-admin/src/main/java/org/apache/shenyu/admin/service/impl/ProxySelectorServiceImpl.java:396-414`
- description: `discoveryHandlerMapper.selectById(discoveryHandlerId)` (398)
is dereferenced at 399; `discoveryMapper.selectById(...)` (399) is dereferenced
at 402/412. `proxySelectorDO` and `selectorDO` are null-checked, but handler
and discovery are not. Exposed via PUT
`/proxy-selector/fetch/{discoveryHandlerId}`.
- impact: Calling fetch with a stale handler id NPEs instead of returning a
not-found result.
- suggested_fix: Guard `discoveryHandlerDO` and `discoveryDO`.
- confidence: Medium
- related_existing: none.
