CVE-2026-61645 - Docat has Arbitrary File Upload exists in Upload API
Docat Upload API 允許未檢驗檔案路徑與型別的任意檔案上傳，攻擊者可上傳惡意檔案，可能導致遠端程式執行或 XSS。
- - 受影響版本：1.6.0 之前的版本。
- - 修復建議：升級至 1.6.0，並嚴格驗證檔案路徑與型別。
- - 潛在風險：可覆寫敏感設定檔或注入惡意指令碼。
Docat is a tool for hosting versioned static documentation. In the affected implementation, an arbitrary file upload vulnerability in the `Upload API` arises because the API does not validate the `uploaded file path or type`. An attacker can overwrite sensitive configuration files or place malicious files on the Docat web server. Depending on deployment context, uploaded content can enable remote code execution or cross-site scripting intended to steal cookies or redirect users to malicious websites. Version 1.6.0 mitigates filename-based path traversal; remediation of unrestricted file types or deployment-dependent malicious-content effects is not established by the verified patch.
