While this release doesn’t introduce new features, it includes several important security fixes that improve overall site protection and reduce risk.

According to Adobe’s official security bulletin, this update resolves multiple vulnerabilities rated Critical and Important, including issues related to:

  • Arbitrary Code Execution – Preventing scenarios where an attacker could execute malicious code under certain conditions.

  • Improper Input Validation – Addressing potential vulnerabilities that could allow attackers to inject or manipulate data.
