Patching Ivanti Sentry Closes the Door. It Doesn't Evict the Guest.
Shadowserver found backdoored Ivanti Sentry instances within 48 hours of the PoC and said the rest are most likely compromised. The patch is step one, not the answer.

regreSSHion proved 'hard to exploit' is not a patch window
CVE-2024-6387 got filed under 'low priority' because it's slow on 64-bit. The CVSS score measured exploit difficulty, not what a root RCE in sshd actually puts at risk.

One cookie to your storefront homepage is shell. CVE-2026-45247 has a Saturday deadline.
An unauthenticated RCE in the Mirasvit Cache Warmer extension is already being hit at scale, and CISA's federal patch deadline is essentially now. If you run Magento, you act today.

The GlobalProtect bypass deadline already passed, but you might not be affected
CVE-2026-0257 is a GlobalProtect auth bypass with a KEV deadline that's come and gone. Whether it touches you comes down to a 60-second config check, not your PAN-OS version.

NGINX Rift: four places apt upgrade doesn't reach
The host patch for CVE-2026-42945 shipped on day one. The container images, the App Protect WAF in front of it, the downstream forks, and the config audit it leaves behind are separate jobs.

Microsoft patched a SYSTEM bug in 2020. It still works in 2026.
A pseudonymous researcher published MiniPlasma, a working PoC for CVE-2020-17103, and the only thing standing between you and a SYSTEM shell is a driver you cannot turn off.

Apache HTTP Server 2.4.49: a path-traversal fix that needed a second fix
CVE-2021-41773 was a path traversal in Apache httpd 2.4.49 that could leak files and, with CGI enabled, reach RCE. The 2.4.50 fix was incomplete, so CVE-2021-42013 followed days later. Two CVEs, one bug, a textbook patch-the-patch.

A new critical Confluence RCE stopped being news. That's the problem.
CVE-2022-26134, CVE-2023-22515, CVE-2023-22518, CVE-2023-22527: Atlassian Confluence Server and Data Center has been mass-exploited so many times that the headline repeats. If you run it on the internet, you're operating one of the most reliably-targeted boxes there is.

The same handful of mechanisms account for most of the catalog
After the marquee bugs, Tier 1's remaining entries, DotNetNuke, ForgeRock, BQE, Sophos, Tomcat, Citrix ShareFile, SAP, Quest, Atlassian Crowd, Exim, Cisco ASA, Office, don't introduce new lessons. They confirm the few recurring mechanisms behind nearly every exploited vulnerability.

Content-process only is one bug short of game over
CVE-2024-9680 was a Firefox use-after-free that 'only' ran code in the sandboxed content process. RomCom paired it with a Windows sandbox escape and turned a single page visit into a backdoor. Mozilla shipped the fix in about 25 hours.

900 old bugs, one answer: patch what's supported, retire what isn't
More than half the KEV catalog is pre-2025 legacy: old Windows, IE, Office, Flash, Java, Apache, and a sea of network gear. They're still listed because they're still exploited on the systems nobody updated. The legacy tier is huge, and its remediation is short.

Why a decade-old Silverlight bug is in a 2022 exploited-vulnerability list
The KEV catalog includes Microsoft Silverlight, Oracle Java, JBoss, and Outside In bugs from 2010 to 2016. They're there because the software is still running somewhere. For most of these, the fix isn't a patch, it's removing a runtime you stopped needing years ago.

The fix shipped in 2015. The CVE came in 2017. The deadline landed in 2024.
CVE-2017-1000253 is a Linux kernel privilege escalation that was already patched upstream two years before it got a CVE. It got a federal deadline the same year CentOS 7 died. 'Patched upstream' never meant 'patched on your box.'

Everyone remembers patching Log4Shell. Few built the thing that would make the next one easy.
CVE-2021-45046 is the bug that proved the first Log4Shell fix was incomplete, kicking off a patch-the-patch cascade in December 2021. The teams that 'patched Log4j' on day one had to do it again, and again. The durable lesson wasn't speed. It was knowing where the dependency lived.

A soft hyphen reopened a bug PHP closed in 2012
CVE-2024-4577 is a patch bypass of a 12-year-old PHP-CGI flaw. The 2012 fix sanitized the input. Windows then helpfully rewrote a soft hyphen back into a real one, after the check, and handed the attacker their command-line argument anyway.

A bug that won $100k at Pwn2Own in March was encrypting SharePoint by winter
The CVE-2023-29357 + CVE-2023-24955 chain gives unauthenticated RCE on SharePoint. It was demoed at Pwn2Own in March 2023, patched mid-year, had a public PoC by late 2023, and hit the KEV list in early 2024. That timeline is something you can plan around.

Two years of Patch Tuesdays, one message: the exploited Windows bug is almost always a privilege escalation
Across 2025 and 2026, Microsoft kept fixing already-exploited Windows flaws, storage drivers, Hyper-V, the network stack, even a 20-year-old third-party modem driver. They don't each need their own post. Together they make one point about patching Windows fast.

The user opened a JPG they could see in the archive. A RAT installed behind it.
CVE-2023-38831 weaponizes the one thing you tell users is safe: opening a file they can see. A WinRAR archive hides a script in a folder named identically to a benign file, and double-clicking the file runs the script. You can't train this away, and WinRAR doesn't auto-update.

The Zimbra bug that infected the mail server when it scanned the attachment
In 2022, Zimbra Collaboration Suite got hammered by a cluster of bugs. One didn't even need the victim to click: send a booby-trapped RAR, and the server unpacked it to scan for malware, infecting itself. On-premise email is the keys to the kingdom, and 2022 proved it.
