CVE-2022-27800: Adobe Acrobat Reader DC Annotation Use-After-Free Remote Code Execution Vulnerability

Acrobat Reader DC versions 22.001.20085 (and earlier), 20.005.3031x (and earlier) and 17.012.30205 (and earlier) are affected by a use-after-free vulnerability in the processing of annotations 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.

Security readout for executives and security teams

Plain-English summary

This flaw lets a malicious PDF trigger code execution in Adobe Acrobat Reader DC when a user opens the file. The attacker gains the same rights as the current user, so business impact depends heavily on endpoint privileges and PDF-handling workflows.

Executive priority

Treat as a high-priority endpoint patching issue, not an internet-exposed server emergency. Focus on rapid coverage for employees handling outside documents and accounts with elevated privileges.

Technical view

CVE-2022-27800 is a CWE-416 use-after-free in Acrobat Reader DC annotation processing. Affected versions include 22.001.20085 and earlier, 20.005.3031x and earlier, and 17.012.30205 and earlier. CVSS is 7.8 with user interaction required.

Likely exposure

Exposure is likely on workstations running affected Adobe Acrobat Reader DC versions, especially users receiving PDFs by email, web download, client portals, or document-sharing platforms.

Exploitation context

The provided sources do not show CISA KEV listing or confirmed active exploitation. Exploitation requires convincing a victim to open a malicious file, then code may run as that user.

Researcher notes

Evidence supports memory-corruption RCE through annotation handling with UI required. The bundle does not provide exploit details, fixed build numbers, or active exploitation evidence beyond KEV=false.

Mitigation direction

  • Inventory Acrobat Reader DC versions across managed endpoints.
  • Apply Adobe guidance from APSB22-16 without inventing fixed version assumptions.
  • Prioritize users who routinely open external PDFs.
  • Reduce local administrator use on PDF-handling endpoints.
  • Warn users against opening unexpected PDF attachments until remediated.

Validation and detection

  • Confirm installed versions are not within the affected version ranges.
  • Verify remediation status against Adobe APSB22-16.
  • Check vulnerability scanner results for CVE-2022-27800 coverage.
  • Review endpoint software inventory for legacy Acrobat Reader tracks.
  • Assess PDF intake workflows for external-file exposure.
