Overview<\/strong><\/p>\n

This blog post focuses on the discovered vulnerability CVE-2025-56803. This vulnerability has been identified in Figma Desktop for Windows version 125.6.5, a popular designing tool used worldwide. The vulnerability is of critical<\/a> importance because it allows an attacker to execute arbitrary OS commands. This can potentially lead to system<\/a> compromise and data leakage, which can have severe consequences for both individuals and organizations.
\nThe vulnerability arises due to a flaw in the local plugin loader which lacks proper validation, thus leading to possible Remote Code Execution<\/a> (RCE). However, it’s important to note that the Supplier has disputed this claim, arguing that the behavior simply allows a local user<\/a> to attack themselves via a local plugin and that the local build procedure, essential to the attack, is not executed for plugins shared to the Figma Community.<\/p>\n

Figma Desktop for Windows | 125.6.5<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The exploit takes advantage of a command injection vulnerability<\/a> in the local plugin loader of Figma Desktop for Windows version 125.6.5. An attacker can execute arbitrary OS commands<\/a> by setting a crafted build field in the plugin’s manifest.json. This field is passed to child_process.exec without any form of validation, potentially leading to Remote Code Execution<\/a> (RCE).<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

The following pseudocode demonstrates how an attacker might exploit this vulnerability by manipulating the manifest.json of a Figma plugin:<\/a><\/p>\n

{\n\"name\": \"Malicious Plugin\",\n\"build\": \"os.system('rm -rf \/')\", \/\/ arbitrary OS command\n\"main\": \"main.js\",\n\"ui\": \"ui.html\"\n}<\/code><\/pre>\n
In this conceptual example, the “build” field in the manifest.json contains a malicious OS command (`rm -rf \/`), which, if executed, would delete all files<\/a> in the system. Note that this is purely a hypothetical example and such a command should never be used in a real-world scenario.<\/p>\n","protected":false},"excerpt":{"rendered":"
