Who should care

Security, IT, and endpoint management teams that may still have Adobe Flash Player installed or reachable; owners of legacy web apps, kiosks, VDI images, and other systems that could still depend on Flash; incident responders tracking KEV-listed items.

Technical summary

The vulnerability is identified as an Adobe Flash Player use-after-free issue. CISA’s KEV record marks it as a known exploited vulnerability and states that the impacted product is end-of-life. The KEV entry was added on 2022-04-13 with a remediation due date of 2022-05-04, indicating the urgency assigned by CISA for any still-exposed deployment.

Defensive priority

Critical and immediate for any remaining exposure. Because Adobe Flash Player is end-of-life and the vulnerability is KEV-listed, organizations should treat any still-installed or reachable instance as a high-priority removal or isolation item.

Recommended defensive actions

  • Inventory assets for Adobe Flash Player installations, embedded dependencies, and legacy workflows that still require Flash.
  • Remove or disable Flash Player wherever possible; do not keep end-of-life instances exposed.
  • If removal is not immediately possible, disconnect affected systems from networks and restrict access while migration or retirement is completed.
  • Check browsers, VDI templates, kiosk images, and legacy applications for hidden Flash dependencies.
  • Track the item as a KEV remediation priority and confirm closure with asset or configuration validation.
