UBUNTU-CVE-2026-13311

shell-quote prior to 1.8.5 finalizes parsed tokens in parse using Array.prototype.concat as a reduce accumulator, which reallocates and copies the entire growing array on every iteration. As a result parse runs in On^2 time relative to the number of input tokens. An attacker who can supply an...

CVE-2026-13311

The CVE affects the shell-quote library prior to version 1.8.5. The parse() function accumulates tokens by using Array.prototype.concat as a reduce accumulator, causing O(n^2) time relative to token count and enabling a potential denial of service by blocking the Node.js event loop with small, at...

CVE-2026-46529

Atril Document Viewer is the default document reader of the MATE desktop environment for Linux. A single-click remote code execution vulnerability in versions prior to 1.26.3 and 1.28.4 allows an attacker to achieve arbitrary code execution as the user by tricking them into clicking a link inside...

OS Command Injection

shell-quote is vulnerable to OS Command Injection. The vulnerability is due to insufficient validation and escaping of object-token .op inputs in the quote function, which allows an attacker to inject line terminators and execute arbitrary shell commands when the generated output is processed by ...

GHSA-W7JW-789Q-3M8P shell-quote quote() does not escape newlines in object .op values

Summary shell-quote's quote function did not validate object-token inputs against the operator model used by parse. The .op field was backslash-escaped character by character using /./g, which in JavaScript does not match line terminators \n, \r, U+2028, U+2029. A line terminator in .op therefore...
