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
Acrobat Reader versions 24.001.30365, 26.001.21651 and earlier are affected by a Use After Free 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.

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

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 if Adobe Acrobat or Reader is installed
    On Windows, open Programs and Features or check registry key HKLM\SOFTWARE\Adobe. On macOS, check /Applications for Adobe Acrobat or Adobe Reader. Also check Start menu shortcuts.
    Affected if Adobe Acrobat Dc, Adobe Acrobat Reader Dc, or Adobe Acrobat is present on the system
  2. Identify the installed version number
    On Windows: Right-click the application in Programs and Features and select Properties, then view the Version field. Or open the application, go to Help > About Adobe Acrobat/Reader. On macOS: Right-click the app in Applications > Get Info.
    Affected if The version shown is 26.001.21651 or earlier, or 24.001.30365 or earlier (for the 24.x track), or any version from 15.008.20082 up to the patched versions
  3. Compare version against affected ranges
    Match your installed version to these ranges: Acrobat Dc/Reader Dc: 15.008.20082 through 26.001.21661 are affected; Acrobat (24.x): 24.0.0 through 24.001.30382 are affected. Versions below 15.008.20082 are not in scope.
    Affected if Your version falls within any of these ranges: 15.008.20082 to 26.001.21661 for Acrobat Dc/Reader Dc, or 24.0.0 to 24.001.30382 for Acrobat 24.x
  4. Determine if PDF files can be opened by the application
    Verify that the PDF open action is associated with the installed Adobe application. Check default file associations in Windows (Settings > Apps > Default Apps > Choose default apps by file type) or on macOS (right-click any PDF > Get Info > Open with).
    Affected if PDF files are set to open automatically with the vulnerable Adobe application, increasing exposure to malicious PDFs

If Adobe Acrobat Dc, Acrobat Reader Dc, or Acrobat (24.x) is installed and its version falls within 15.008.20082-26.001.21661 (for DC products) or 24.0.0-24.001.30382 (for Acrobat 24.x), the environment is affected.
