CVE-2025-56803 — Figma Desktop for Windows version 125.6.5 contains a command injection vulnerability in the local plugin loader

High CVSS 8.4

Figma Desktop for Windows version 125.6.5 contains a command injection vulnerability in the local plugin loader. An attacker can execute arbitrary OS commands by setting a crafted build field in the plugin's manifest.json. This field is passed to child_process.exec without validation, leading to possible RCE. NOTE: this is disputed by the Supplier because the behavior only allows a local user to attack himself via a local plugin. The local build procedure, which is essential to the attack, is not executed for plugins shared to the Figma Community.

Matched remediation archetype

Command, code, expression, and template injection

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted values to process execution, interpreters, evaluators, template engines, dynamic imports, and administrative scripting features.
  • Determine whether the affected path is reachable across each trust boundary and which service account or host privilege it inherits.
  • Review configuration for optional execution features, unsafe compatibility modes, and shell invocation.

Remediate safely

  • Replace string-built commands or evaluated code with fixed operations and structured argument APIs that do not invoke a shell.
  • Use strict allowlists for operation identifiers and reject unexpected input before it reaches any interpreter.
  • Update the affected component and add inert regression tests covering metacharacters, encoding variants, and alternate request paths.
