Critical CVSS 9.8 CISA KEV

Craft is a flexible, user-friendly CMS for creating custom digital experiences on the web and beyond. Users of affected versions are affected by this vulnerability if their php.ini configuration has `register_argc_argv` enabled. For these users an unspecified remote code execution vector is present. Users are advised to update to version 3.9.14, 4.13.2, or 5.5.2. Users unable to upgrade should disable `register_argc_argv` to mitigate the issue.

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.
