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 DC versions 2020.013.20066 (and earlier), 2020.001.30010 (and earlier) and 2017.011.30180 (and earlier) are affected by an information exposure vulnerability, that could enable an attacker to get a DNS interaction and track if the user has opened or closed a PDF file when loaded from the filesystem without a prompt. User interaction is required to exploit this vulnerability.

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

This is an information exposure vulnerability in Adobe Acrobat Reader DC where opening or closing a PDF file loaded from the filesystem can trigger DNS interactions that reveal user activity to an attacker, enabling tracking of file access without prompting the user.

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 installed Adobe product
    Check for installed Adobe Acrobat or Adobe Acrobat Reader on the system. On Windows, look in Programs and Features or check common installation paths like C:\Program Files\Adobe or C:\Program Files (x86)\Adobe. On macOS, check /Applications for Adobe Acrobat or Adobe Acrobat Reader.
    Affected if Adobe Acrobat or Adobe Acrobat Reader (Standard or DC variant) is installed
  2. Determine exact version number
    Open Adobe Acrobat or Reader, then navigate to Help > About Adobe Acrobat (or About Adobe Acrobat Reader) to display the exact version number. Alternatively, on Windows you may check the version property of the executable file in the installation directory.
    Affected if The displayed version matches one of the affected ranges: 17.011.30059 through 17.011.30180, 20.001.30005 through 20.001.30010, or 15.008.20082 through 20.013.20066 (for DC variants)
  3. Confirm product variant (Standard vs DC)
    Verify whether the installed product is Adobe Acrobat/Reader Standard or Adobe Acrobat/Reader DC (Document Cloud). The DC variants have a broader affected range (15.008.20082 to 20.013.20066) compared to the Standard product versions.
    Affected if The product is Adobe Acrobat DC or Adobe Acrobat Reader DC and the version falls between 15.008.20082 and 20.013.20066

You are affected if Adobe Acrobat or Adobe Acrobat Reader (Standard or DC) is installed and its exact version falls within any of the listed vulnerable ranges.
