affected by multiple vulnerabilities as referenced in the APSB26-78 advisory.

  - Out-of-bounds Write (CWE-787) potentially leading to Arbitrary code execution (CVE-2026-48274,
    CVE-2026-48367)

  - After Effects versions 26.0, 25.6.4 and earlier are affected by a Stack-based Buffer Overflow
    vulnerability that could result in arbitrary code execution in the context of the current user.
    Exploitation of this issue requires user interaction in that a victim must open a malicious file.
    (CVE-2026-34690)
