CVE-2025-32778 — Web-Check is an all-in-one OSINT tool for analyzing any website

Critical CVSS 9.3

Web-Check is an all-in-one OSINT tool for analyzing any website. A command injection vulnerability exists in the screenshot API of the Web Check project (Lissy93/web-check). The issue stems from user-controlled input (url) being passed unsanitized into a shell command using exec(), allowing attackers to execute arbitrary system commands on the underlying host. This could be exploited by sending crafted url parameters to extract files or even establish remote access. The vulnerability has been patched by replacing exec() with execFile(), which avoids using a shell and properly isolates arguments.

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.
