CVE-2026-82635— Pake arbitrary file write via unsanitized download_file filename

Quick assessment

Affected
tw93 Pake
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Tw93 Pake是Tw93个人开发者开源的一款将网页打包成桌面应用的软件。 Tw93 Pake 3.13.1之前版本存在路径遍历漏洞，该漏洞源于download_file Tauri命令未对JavaScript提供的文件名进行清理，直接将文件名拼接到用户Downloads目录，包含路径遍历序列或绝对路径的文件名可解析到Downloads目录之外，导致攻击者可覆盖用户可写文件并安装持久化，进而执行任意代码。

Vulnerability Title
Pake arbitrary file write via unsanitized download_file filename
Source: CVE Program / CVE List V5
Vulnerability Description
Pake before 3.13.1 joins the JavaScript-supplied filename for the download_file Tauri command onto the user's Downloads directory with no sanitization. A filename containing path traversal sequences (for example ../Library/LaunchAgents/com.evil.plist) or an absolute path resolves outside ~/Downloads. The command then fetches attacker-controlled content from the supplied URL (via Rust HTTP, not the browser) and writes it to that path. A script that can invoke the command can overwrite user-writable files and install persistence (macOS LaunchAgents, Linux autostart, Windows Startup), leading to code execution in the user account. All desktop apps generated from an affected Pake tree expose the same command.
