ColdFusion 2021 End of Life: Extended Support Ends November 10, 2026

By Scott Bissett  ·  Published: September 18, 2026  ·  Reference guide  ·  Dates read twice at Adobe's support periods matrix on the day of publication.

Adobe ColdFusion 2021 is in its last support phase. Core support ended on November 10, 2025, and extended support ends on November 10, 2026. Both dates are Adobe's own, from its products and technical support periods matrix. Adobe lists no phase after the second date. The versions still in core support are ColdFusion 2023 and ColdFusion 2025.

Why the date matters for this product in particular. ColdFusion is on CISA's Known Exploited Vulnerabilities catalog: attackers have used ColdFusion flaws against real servers, repeatedly. A ColdFusion server is usually internet-facing by design. One that has stopped receiving updates is the kind of system those catalog entries are written about. Our live read is on the ColdFusion page.
Quick answer: Adobe ColdFusion 2025 is supported until February 26, 2030, its end-of-support date. The next Adobe ColdFusion version to reach end of life is 2023, on May 16, 2028. 5 of 7 tracked Adobe ColdFusion versions are past end of life; the most recent to reach it, 2021, did so on November 10, 2025. Every Adobe ColdFusion version's release and end-of-support date is on the Adobe ColdFusion lifecycle page.

Adobe's matrix gives two dates per version and labels them core support and extended support. What each phase includes for your licence is set by Adobe's support lifecycle policy and your agreement; confirm it with Adobe before you plan around the extended year. For ColdFusion 2025 the matrix shows no extended support date.

A note on accuracy: while preparing this guide we found that six ColdFusion dates in the open dataset we draw on did not match Adobe's matrix. We read Adobe's page twice, corrected them the same day, and added an automated check that re-reads Adobe's matrix every day. The dates above are the corrected ones.

What to do

  1. On ColdFusion 2018 or older: every phase Adobe lists has ended. Treat the server as unsupported and internet-exposed: move it, or take it off the internet while you do.
  2. On ColdFusion 2021: you are in the final listed phase, and it ends on November 10, 2026. Plan the upgrade to finish before that date, not start at it. Application testing on a new ColdFusion version is where the time goes.
  3. Choosing a target: ColdFusion 2023 has core support to May 16, 2028; ColdFusion 2025 to February 26, 2030. The later date buys the longer runway.
  4. Check what ColdFusion runs on. The Java runtime, the web server and the operating system under it each have their own end dates. Our EOL Checker and API answer those.
