Analysis

AI-generated

Technical impact

Adobe After Effects versions 25.6 and earlier contain a type confusion flaw (CWE‑843) that allows an attacker to execute arbitrary code in the context of the current user. The vulnerability is triggered when a maliciously crafted project file is opened, leading the application to treat an incompatible data type and write unintended data, thereby granting code execution privileges.

Affected Systems

The flaw affects all installations of Adobe After Effects version 25.6 and older on macOS and Windows platforms. Any user running these versions who opens a malicious or tampered After Effects file is susceptible to exploitation.

Risk and Exploitability

With a CVSS score of 7.8 the vulnerability is classified as high severity, and the EPSS score of less than 1 percent suggests a low but non‑zero probability of exploitation in the wild. Exploitation requires user interaction to open a malicious file, making social engineering or targeted attacks the most likely vectors. The vulnerability is not currently listed in the CISA KEV catalog, but it remains a known risk until the published update is applied.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the latest Adobe After Effects update (version 25.7 or later) that addresses the type‑confusion vulnerability.
  • Educate users to avoid opening unfamiliar files and to verify the source before opening them.
  • Deploy reputable security software that scans attachments and blocks malicious file types before they reach After Effects.
