CVE-2026-73244: Kekingcn Kkfileview

Medium severity, CVSS 5.3. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Kekingcn Kkfileview: before 5.0.1 (fixed in 5.0.1)
