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 memory 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 memory corruption vulnerability when parsing specially crafted files. An attacker can craft a malicious file that, when opened by a victim, triggers memory corruption leading to arbitrary code execution in the context of the current user. User interaction is required (opening the malicious file) for exploitation.

MitigationUpdate Adobe After Effects to version 18.2.1 or later to remediate this vulnerability. Additionally, train users to avoid opening files from untrusted sources.

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. Check installed After Effects version
    Open After Effects and go to Help > About Adobe After Effects, or on Windows right-click the After Effects executable in Program Files and select Properties > Details to see the Product Version
    Affected if The version displayed is 18.2 or earlier (18.0, 18.1, 18.2)
  2. Verify version via Adobe Creative Cloud
    Open Adobe Creative Cloud desktop app, click on the icon next to After Effects, and select 'View All' or 'Update' to see currently installed version
    Affected if The installed version shown is 18.2 or lower
  3. Confirm application is vulnerable when parsing files
    This vulnerability triggers when After Effects opens a specially crafted malicious file - the vulnerability exists in the file parsing logic for project files
    Affected if Any version 18.2 or earlier is vulnerable regardless of file parsing settings, as this is a flaw in how the application handles file input

If your installed Adobe After Effects version is 18.2 or earlier, your environment is affected by this vulnerability and could be exploited by opening a malicious file.
