CVE-2026-21319
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 · uneditedAfter Effects versions 25.6 and earlier are affected by an Out-of-bounds Read vulnerability that could lead to memory exposure. An attacker could leverage this vulnerability to access sensitive information stored in memory. 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 · moderate confidenceAfter Effects versions 25.6 and earlier contain an out-of-bounds read vulnerability. When a victim opens a specially crafted malicious file, the application reads beyond allocated memory boundaries, potentially exposing sensitive data from the process memory space.

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 checksWork through these to decide whether this CVE applies to you.
-
Verify After Effects is installedCheck for After Effects installation. On Windows, look in Program Files\Adobe or check installed programs list. On macOS, check /Applications for Adobe After Effects.app.Affected if After Effects is present on the system
-
Determine installed After Effects versionOpen After Effects and navigate to Help > About After Effects to view the exact version number. Alternatively, on Windows right-click the After Effects executable, select Properties, and view the File version in the Details tab.Affected if Unable to retrieve the installed version
-
Compare version against affected rangeCompare the installed version number to 25.6.4. The affected range includes any version lower than 25.6.4 (for example: 25.6, 25.5, 25.0, 24.x, or earlier).Affected if Installed version is 25.6.3 or any earlier version number
If the installed After Effects version is below 25.6.4, the environment is vulnerable to the out-of-bounds read when opening specially crafted files.
