@matheusmourafpf

Hello,

A security scan on a Flutter-based mobile application identified the CVE-2025-27363
affecting the FreeType library (out-of-bounds write, potential RCE).

Current situation:

  • The application itself does not include FreeType directly
  • FreeType is bundled through Skia in Flutter
  • Security scanners detect FreeType version <= 2.13.0, which is affected by CVE-2025-27363

Impact and Severity:

  • The vulnerability may result in arbitrary code execution, depending on how the affected FreeType code paths are used.
  • The CVSS v3.1 score is 8.1 (HIGH) according to NVD.
  • This CVE is listed in the CISA Known Exploited Vulnerabilities (KEV) Catalog, indicating potential exploitation in the wild.

Known Remediation Requirements:

  • FreeType versions ≤ 2.13.0 are affected
  • FreeType ≥ 2.13.1 includes the fix and is not affected by this vulnerability

References:

Questions:

  1. Is there a planned update to Skia/FreeType to address CVE-2025-27363?
  2. Is there any recommended mitigation for Flutter applications until an official update is available?
