This issue affects Apache HTTP Server: from 2.4.60 through 2.4.68.
A flaw was found in Apache HTTP Server. An attacker could achieve unintended code execution when an internal redirect generated by a Common Gateway Interface (CGI) program points to a non-executable file. If the target file resides in a directory configured for CGI execution and lacks a file extension recognized by the MIME handler, the server incorr

## ⚡ Weekly Recap: NetScaler and FortiMail 0-Days, AI Coding Leaks, Spectre v2 and Ransomware Arrests
A blank field. A public repo. One reply to an email. A box left exposed. None of this sounds dramatic, which is partly the problem. This week’s threats keep finding leverage in small things that were easy to overlook.
There are actively exploited bugs in the mix, cleaner intrusion paths, smarter automation, and a long patch list waiting behind them. Some attacks are getting more capable. Others are still getting in because the basics gave way first.
Here’s what mattered this week.
