CVE intelligence and bounded remediation

CVE-2025-55313 — An issue was discovered in Foxit PDF and Editor for Windows and macOS before 13.2 and 2025 before 2025.2

High CVSS 7.8

An issue was discovered in Foxit PDF and Editor for Windows and macOS before 13.2 and 2025 before 2025.2. They allow potential arbitrary code execution when processing crafted PDF files. The vulnerability stems from insufficient handling of memory allocation failures after assigning an extremely large value to a form field's charLimit property via JavaScript. This can result in memory corruption and may allow an attacker to execute arbitrary code by persuading a user to open a malicious file.

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.
