## ⚡ Weekly Recap: Exchange 0-Day, npm Worm, Fake AI Repo, Cisco Exploit and More
Monday opens with a trust problem. A mail server flaw is under active use. A network control system was targeted. Trusted packages were poisoned. A fake model page pushed a stealer. Then came the familiar ransom claim: the data was returned and deleted.
The pattern is clear. One weak dependency can leak keys. One leaked key can open cloud access. One cloud foothold can become a production incident. AI is speeding up vulnerability discovery, attackers are moving quickly, and old exposure still keeps paying off.
Patch the quiet risks first. Let’s g

CVE-2026-24308 [HIGH] CVE-2026-24308 Apache ZooKeeper: Apache ZooKeeper: Information disclosure via improper handling of configuration values
CVE-2026-24308 Apache ZooKeeper: Apache ZooKeeper: Information disclosure via improper handling of configuration values
Improper handling of configuration values in ZKConfig in Apache ZooKeeper 3.8.5 and 3.9.4 on all platforms allows an attacker to expose sensitive information stored in client configuration in the client's logfile. Configuration values are exposed at INFO level logging rendering potential production systems affected by the issue. Users are recommended to upgrade to version 3.8.6 or 3.9.5 which fixes this issue.

CVE-2026-1605 org.eclipse.jetty/jetty-server: Eclipse Jetty: Denial of Service due to unreleased JDK Inflater from compressed HTTP requests

CVE-2026-1605 [HIGH] CVE-2026-1605 org.eclipse.jetty/jetty-server: Eclipse Jetty: Denial of Service due to unreleased JDK Inflater from compressed HTTP requests
CVE-2026-1605 org.eclipse.jetty/jetty-server: Eclipse Jetty: Denial of Service due to unreleased JDK Inflater from compressed HTTP requests
In Eclipse Jetty, versions 12.0.0-12.0.31 and 12.1.0-12.0.5, class GzipHandler exposes a vulnerability when a compressed HTTP request, with Content-Encoding: gzip, is processed and the corresponding response is not compressed.
This happens because the JDK Inflater is allocated for decompressing the request, but it is not released because the release mechanism is tied to the compressed response.
In this case, since the response is not compressed, the release mechanism does not trigger, causing the leak.
