Adobe Acrobat and Reader, Flash Player Unspecified Vulnerability
What it is
Adobe Acrobat and Reader and Adobe Flash Player allows remote attackers to execute code or cause denial-of-service (DoS).
Who's affected
Affects anyone opening, editing, or signing PDFs in Adobe Acrobat or Reader. For a CPA or legal practice, PDFs are typically client tax returns, engagement letters, signed agreements, and discovery documents — opening a malicious PDF runs attacker code in the user's session, which can pivot to file shares or email.
What to do
For Adobe Acrobat and Reader, apply updates per vendor instructions. For Adobe Flash Player, the impacted product is end-of-life and should be disconnected if still in use.
CISA action deadline: June 22, 2022. Federal agencies must complete the required action by this date. For private SMBs the deadline is advisory — but treat it as a strong recommendation, especially if you handle regulated data (HIPAA, GLBA, ABA model rules).
