Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Adobe After Effects version 18.2 (and earlier) is affected by a heap corruption vulnerability when parsing a specially crafted file. An unauthenticated attacker could leverage this vulnerability to achieve 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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Adobe After Effects version 18.2 and earlier contains a heap corruption vulnerability during file parsing. When a user opens a specially crafted malicious file, the heap corruption can be triggered, potentially allowing an attacker to execute arbitrary code in the context of the current user's privileges.

MitigationUpdate Adobe After Effects to version 18.2.1 or later. Additionally, exercise caution when opening files from untrusted sources and consider implementing network-level file type restrictions.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Adobe After Effects installation
    On Windows, check the installed version via the Windows Registry at HKEY_LOCAL_MACHINE\SOFTWARE\Adobe\After Effects\[version] or by opening After Effects and navigating to Help > About Adobe After Effects. On macOS, right-click the application in /Applications and select Get Info to view the version.
    Affected if Adobe After Effects is installed on the system
  2. Determine installed version number
    Locate the full version number (such as 18.0, 18.1, or 18.2) from the version check performed in the previous step. Note that version 18.2.1 and later are patched.
    Affected if The version cannot be determined or is 18.2 or earlier
  3. Compare against affected version range
    Compare the identified version against the affected range. Versions 18.2 and earlier (including 18.0, 18.1, and 18.2) are vulnerable. Version 18.2.1 and later are not affected.
    Affected if The installed version is 18.2 or earlier

If Adobe After Effects version 18.2 or earlier is installed, the environment is affected by this heap corruption vulnerability.
