Improper authorization in Novel-Plus 0e156c04b4b7ce0563bef6c97af4476fcda8f160 allows remote authenticated users to read system logs. The GET /common/log/list handler passes request parameters to logService.queryList and returns PageDO without a method-level authorization check. Any authenticated account that can reach the administration service can retrieve log entries, with no reported write or service-interruption impact.
