One explanation and solution for when applying CF updates uninstalls new packages unexpectedly

I offer in this post a solution to a problem that I and others experienced regarding the latest CF update (released Dec 10, 2025 for ColdFusion 2025, 2023, and 2021, which I just blogged about separately).

We only experienced it with CF2023, but others have reported the problem in the past, with various CF updates to any CF version. As I'll explain it seems to be a caching problem relative to Adobe's servers (so some people may experience it, but not others):

  • First, you may find that after applying the update all the of the packages that were to be updated by the release will instead be UINSTALLED unexpectedly/
  • Even worse, that could mean that the administrator package is uninstalled, such that you can't get to the CF Admin after the update...which will also mean you can't use the admin to try to "uninstall the update" (if you wanted to).

Of course, you could go the command line route, as you would be told to consider doing if the Administrator package was uninstalled, using CF's cfpm tool to either install the admin package or even perhaps try to uninstall the update entirely.

But I have what seems to be a better solution. It's quite simple, but bear with me while I explain it...both to help you (and Adobe) better understand what seems amiss, and in case more info may come out soon from them or other folks.

Beware also that if you may have "solved the problem" yourself, consider what I have to say below--you should confirm that you DO in fact have the correctly UPDATED packages, which you may have installed using that cfpm tool.

Announcing ColdFusion updates released Dec 9 2025 - p1 security update and more

An update for ColdFusion has been released, Dec 9 2025, for each of cf2025 (update 5), cf2023 (update 17) and cf2021 (update 23). This is in fact that FINAL update of CF2021, as it has reached its end of life as I blogged last month.

In brief, this update (for all 3 versions) ad.dresses several P1 (Priority 1, "Critical") security vulnerabilities, and also updates Tomcat, along with updating several CF packages, and makes some other changes (see below). Note that Adobe is also reporting currently that, "Adobe is not aware of any exploits in the wild for any of the issues addressed in these updates."

In this post, I share the details about the update (from Adobe and from others). I also share additional info you may want to consider before (or after) doing the update. 

Having installed the update for each of the releases on multiple machines, I can report that it went well expect for this:

Warning: beware that some folks implementing the update for CF2023 the first day (myself included) found that after applying the update, the CF Admin was inaccessible and packages that were updates were unexpectedly uninstalled. I have offered a follow-up blog post on that, One explanation and solution for when applying CF updates uninstalls new packages unexpectedly, including how to solve the problem as I see it, and how to ensure your own manual efforts to solve it are complete.

Announcing ColdFusion updates released Sep 9 2025 - p1 security update

An update for ColdFusion has been released, Sep 9 2025, for each of cf2025 (update 4), cf2023 (update 16) and cf2021 (update 22). In brief, it addresses a single P1 (Priority 1, "Critical") security vulnerabilities, along with an indicated update to the "feed" package (used by cffeed). Note that Adobe is also reporting currently that, "Adobe is not aware of any exploits in the wild for any of the issues addressed in these updates." More below.

As usual, there are a number of things you should consider before (or after) doing the update, with some discussed in Adobe's resources on the update (there are more than one), and some info that I share below based on my experience helping people apply this and past updates.

In this post, I share the details about the update (from Adobe and from others). I can report I have installed the update for each release on multiple machines and operating systems without any major incidents. As for challenges (common to recent releases) and lessons learned (about this update), read on.

An update for ColdFusion has been released, July 8 2025, for each of cf2025 (update 3), cf2023 (update 15) and cf2021 (update 21). In brief, it addresses a number of P1 (Priority 1, "Critical") security vulnerabilities and more, including bug fixes and some modest feature changes.

As usual, there are a number of things you should consider before (or after) doing the update, with some discussed in Adobe's resources on the update (more than one), and some that I share below based on my experience helping people apply this and past updates. Finally, the update corrects some issues introduced in the previous updates, released in May.

Announcing ColdFusion updates released May 13 2025 - p1 security update (and more)

An update for ColdFusion has been released, May 13, 2025, for both cf2025 (update 2), cf2023 (update 14) and cf2021 (update 20). In brief, it addresses a P1 (Priority 1, "Critical") security vulnerability, as indicated in the associated ASPB (security bulletin) for the update.

The update also incorporates potentially breaking changes (with Adobe trading compatibility for security), while it also includes configurable options to undo those changes (if you prefer to trade away security for compatibility). Finally, the update corrects some issues introduced in the previous updates, released in April.

In this post, I share the details about the update (from Adobe and from others). I can report I have installed both updates on multiple machines and operating systems without incident. As for challenges or lessons learned, I may do a follow-up post as I/we all learn more.

For more details, read on.

Delighted to be speaking at Into the Box 2025, in early May

I'm delighted to announce that I've been selected to speak at the upcoming Into the Box event (in DC in early May), where I'll be presenting "Hidden Gems in FusionReactor: for BoxLang, ACF, and Lucee Users".

This should not be confused of course with the "Hidden Gems in CF2025" talk which I also just announced that I'd be presenting at the upcoming CF Summit East (next week in DC) and CFCamp (in Munich in late May). It'll be a busy few weeks! :-)

As with them, it's always a thrill to attend this annual event. Following is the topic description and more.

A table of Java versions supported by given ColdFusion versions

Now that CF2025 has come out, supporting Java 21--and as ColdFusion and Java versions continue to evolve--you may wonder which version(s) of Java you can use with your current (or a given) version of ColdFusion.

You can't just use "any" jvm version with CF: it depends on first on what version of CF you are using, and then may even depend on what CF update has been applied to that CF version. (You also can't use Java from any vendor: Adobe supports only use of Oracle Java, and they license it for our use, as I discuss later.) And to be clear, currently ONLY CF2025 supports Java 21. (And with Java 24 coming out in Mar 2025 as the latest LTS or "long-term support" Java releases, note that NO CF version currently supports that.)

So in this post, I offer a table that clarifies things, listing the various recent CF versions (even those no longer supported) and what (LTS) Java versions they supported, including if some CF update of a version changes the Java version supported.

ColdFusion 2025 released, Feb 25 2025 - resources and my initial thoughts

ColdFusion 2025 has been released today, Feb 25 2025. In this post I am not only helping share news of the release, and pointing to available resources, but I also share some thoughts/observations on related matters that may be a bit challenging for most to find more about on their own (if they may only assess a couple of resources, or hear only tidbits shared in social media).

First, for more on the many features and changes, I share many Adobe resources--about which I also offer some additional comment. I also discuss changes regarding OS and DB support as well as the fact that CF2025 now runs on Java 21-- and that the traditional server deployment of CF comes installed atop Tomcat 10.1. I then share still more info on other matters and resources related to the new version.

I then focus on the major change in licensing, for CF2025 and forward, to being subscription only--which I'll note has no effect on those currently running CF2023 or earlier. I share pricing info and also help in assessing differences in the EULA, and more.

Finally I discuss some migration considerations--including important REMOVAL of some older features from CF2025, as CF continues to be made more secure and modernized. I also identify tools and resources to help aid you in that migration, when you're ready to begin attempting it.

For all that and more, read on.

Last chance to save 25% off CF2023, for those on CF2018 and earlier

Here's great news for those still running CF2018 or earlier, who may have been holding off upgrading to CF2023 (because you would have to pay full price for it). It's news I first shared back in July, and the deal has been extended one last time, thus this post.

TLDR; Now through Feb 28, 2025 those running CF9, 10, 11, 2016 or 2018 can upgrade to CF2023 for 25% off its full price. (Those running CF2021 can already/always could upgrade at 50% off the full price.)

This is a deal offered only by Intergral, makers of FusionReactor, who are also resellers of CF. Adobe doesn't even offer this deal themselves. For more, see their blog post at https://fusion-reactor.com/blog/news/save-25-on-adobe-cf2023-upgrades/.

Act now, it could save you hundreds or even thousands of $$s on a single license! For more, read on.
