August 31, 2026 Doug Bidwell
After the deluge of the past two weeks with so many security vulnerabilities and patches for the IBM i platform, you are going to get an easier week now. This may or may not have to do with the vacation schedules of IBMers who try to kill bugs, or it may have to do with the impending Labor Day holiday in the United States.
Who knows? Take the easy week while you have it. We are off next week for the holiday, and we will catch you up on the patches and vulnerabilities when we return on September 14.

August 24, 2026 Doug Bidwell
It looks like 28 is not your lucky number if you are an IBM i shop. The reason why is that in Volume 28 and Number 28 of the IBM i PTF Guide, Big Blue has released a truly amazing number of security vulnerabilities and patches for the IBM i platform. We counted 40 security vulnerabilities, some of which are still awaiting patches, plus 22 High Impact/Pervasive (HIPER) patches for firmware on Power9, Power10, and Power11 systems. But a few items before we dive into that.
First: The System Planning Tool, version 6.26.223.0, is now available for download at …

IBM laid a lot of PTF work on you last week, and this week is also a heavy one. So brace yourself. There are six security vulnerabilities in the IBM i stack and several other issues that you should be aware of. Let’s start with the random issues and then do the security issues.
First, known issues (APARs) have been fixed for IBM i Access Client Solutions, ACS 1.1.9.15 (ACS11915), and here is the Klingon that describes it: DT498800 OSP-UNPRED MSGSSL007 – AN ERROR OCCURRED WITH AN SSL CERTIFICATE (JAVA.NIO.FILE.ATTRIBUTE.USERPRINCIPALNOTFOUNDEXCEPTION).

Welcome to this week. You have some issues with IBM i Access Client Services to deal with as well as a new security bulletin.

- Zip slip path traversal exploit when importing a configuration.
- Versions 1.1.8.3 through 1.1.9.13 are vulnerable to downloading unverified

The flow of security vulnerabilities and PTF patches has been kind of spotty for the past several weeks. Which is good, because we were in transit across the United States. We have successfully relocated from California to Pennsylvania, and are settling in. We are almost unpacked, and my Network Operations Center, or NOC, is coming together. Thanks for your patience!
Here is the rundown of PTF Groups by IBM i release level since we last published:
PTF Groups 7.6:
- HIPERs (High Impact/Pervasive)
- Security
- WebSphere Application Server V8.5
