kkFileView: Unauthenticated path traversal in POST /listFiles allows arbitrary directory listing

kkFileView is a universal file online preview project based on Spring Boot. Prior to 5.0.1, the unauthenticated POST /listFiles endpoint in server/src/main/java/cn/keking/web/controller/FileController.java passes the user-controlled path parameter from FileController#getFiles to Files.newDirectoryStream without confinement to the demo directory, allowing directory enumeration outside the intended root. This issue is fixed in version 5.0.1.

kkFileView: Unauthenticated SSRF via /addTask with fullfilename type-confusion bypass

kkFileView is a universal file online preview project based on Spring Boot. Prior to 5.0.1, the unauthenticated GET /addTask endpoint in kkFileView is omitted from TrustHostFilter and TrustDirFilter in server/src/main/java/cn/keking/config/WebConfig.java, allowing FileConvertQueueTask to fetch an attacker-selected URL after FileHandlerService#getFileAttribute uses the fullfilename parameter to force an OFFICE, COMPRESS, or CAD type. This issue is fixed in version 5.0.1.
