Adobe Animate versions 24.0.8, 23.0.11 and earlier are affected by an Integer Underflow (Wrap or Wraparound) vulnerability identified as CVE-2025-43555. The vulnerability was discovered and disclosed on May 13, 2025, affecting both Windows and macOS operating systems (NVD).

The vulnerability is classified as an Integer Underflow (Wrap or Wraparound) issue, tracked under CWE-191. It has received a CVSS v3.1 Base Score of 7.8 (HIGH), with a vector string of CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H. The vulnerability requires user interaction for successful exploitation, specifically requiring a victim to open a malicious file (NVD, Wiz).

If successfully exploited, this vulnerability could lead to arbitrary code execution in the context of the current user.

Adobe has released security updates to address this vulnerability. Users are advised to update to versions newer than Adobe Animate 24.0.8 and 23.0.11. Organizations should implement the principle of least privilege and restrict administrator privileges to dedicated administrator accounts (Wiz).
