Your backup server is joined to the domain it exists to recover
Joining your backup server to the production Active Directory domain puts your last line of recovery inside the same trust boundary as the systems it protects, so one Domain Admin compromise reaches the backups too. Here is the evidence and what to change.

Commvault CVE-2025-34028: upgrading to 11.38.20 is not the whole fix
CVE-2025-34028 gives pre-auth RCE on Commvault Command Center. The patch landed in April and the federal deadline passed in May, but the fix requires supplemental update packages beyond the base version, and most shops check the version number and stop there.

Jenkins CVE-2024-23897: from 'limited file read' to your secret key
The KEV entry calls it 'limited read access to certain files.' On a Jenkins controller, the files include the cryptographic key that turns read into remote code execution. Here's how to check, patch, and what to rotate if you were exposed.

The Linux firewall bug your users can reach because you gave them a private root
CVE-2024-1086 is an nf_tables use-after-free that hands a local user root. The reason an unprivileged user can touch the kernel's packet-filtering engine at all is unprivileged user namespaces, and turning those off defuses a whole class of these bugs at once.

The most dangerous server in the hospital is the one nobody can name
Mirth Connect moves patient records between systems and runs with high privileges, and a lot of installs sit on the open internet. CVE-2023-43208 is an unauthenticated RCE in it, and it's a patch bypass: the first fix used a denylist, and a researcher walked around it.

The other half of the ScreenConnect chain just got a 2026 deadline
CVE-2024-1709 got the CVSS 10 and the headlines in February 2024. The path-traversal half that actually lands code execution, CVE-2024-1708, only got its own KEV deadline on April 28, 2026. Two years late, same chain.

Five hours from public PoC to live exploitation on your monitoring server

The fix shipped on September 3, 2024. The CVE assignment came eleven weeks later, after Helldown was already in production networks. The customers who patched on time still got compromised.

SimpleHelp CVE-2024-57727: a seven-day patch and a sixteen-month leak
SimpleHelp shipped a fix in seven days from full disclosure. Then they posted it to a forum. Ransomware affiliates have been pulling hashed admin credentials out of unpatched servers ever since.

Cleo shipped a fix in October. Cl0p was bypassing it by December.
CVE-2024-50623 was patched in 5.8.0.21 on October 27. By December 3, Huntress had a working PoC against fully patched hosts and Cl0p was running it in production. This is the fifth MFT vendor in five years to hand Cl0p the same playbook.

Five critical Fortinet CVEs in 28 months is not a streak of bad luck
Three heap overflows, two auth bypasses, all pre-auth, all ransomware-linked. The pattern in FortiOS and FortiProxy is structural, and patching alone has not been enough to remove attacker access.

Three root shells in seven months. All from the same firewall.
CVE-2024-3400, CVE-2024-0012, and CVE-2024-9474 gave attackers unauthenticated root on Palo Alto firewalls twice in 2024. The pattern isn't bad luck. It's the architecture.

The researcher who reported two Windows bugs to Microsoft was exploiting a third
CVE-2025-26633 turns MMC's localization feature into a code execution vector. EncryptHub exploited it as a zero-day while simultaneously disclosing other vulnerabilities to Microsoft for credit.

Citrix shipped CitrixBleed again
Citrix shipped the same pre-auth memory disclosure bug class it patched in 2023. Same binary, same attack surface, same session token leakage. Its own post-patch guidance still doesn't invalidate the tokens attackers actually steal.

CrushFTP chose the narrative over its customers
CrushFTP tried to keep a CVSS 9.8 auth bypass quiet. The disclosure mess that followed, two CVEs, public PoC code, and CEO threats, helped attackers move faster.

Six zero-days in three years: the CLFS pattern Microsoft can't outrun
Microsoft patched a CLFS zero-day on April 8 but left Windows 10 without a fix for five weeks. Two unrelated ransomware groups were already using it. It was the sixth CLFS zero-day since 2022.

Oracle blamed its customers for a zero-day it hadn't patched
Oracle's first public statement during active Cl0p exploitation told customers the breach was their fault for not applying a patch that didn't exist. The correction came Saturday night, behind a paywall.

BeyondTrust RS/PRA hit again. Same endpoint, same bug class, 15 months later.
The researcher who found CVE-2026-1731 did it by asking one question about the December 2024 fix: did the same pattern exist elsewhere? It did. Third critical BeyondTrust RCE in 15 months, confirmed ransomware, CISA gave you 3 days.

Exchange's deserialization problem didn't start in 2023. It still isn't fixed.
A ransomware group picked up a three-year-old Exchange RCE because scanning at scale still finds unpatched servers. The bug isn't the story. The patching economics are.

PaperCut's other bug just became a ransomware vector again
CVE-2023-27351, the auth bypass that lived in CVE-2023-27350's shadow, is back. Storm-1175 is deploying Medusa ransomware through it with sub-24-hour exploitation tempo. CISA added it to KEV in April 2026. If you patched the RCE in 2023 and moved on, check whether the auth bypass actually closed.

SharePoint's two-week window: patched servers were still exploitable

SmarterMail fixed a CVSS 10 and told no one for two months
CVE-2025-52691 is a pre-auth RCE in SmarterMail's file upload API. SmarterTools patched it silently in October 2025 with no CVE, no advisory, and release notes that said 'critical security fixes.' watchTowr found the silent fix two months later. Here's why that matters.

TeamCity's path traversal took two years to reach KEV. That's a long time to leave a CI server exposed.
CVE-2024-27199, a path traversal in JetBrains TeamCity On-Premises, was patched in March 2024 and exploited by BianLian ransomware within days. CISA added it to KEV in April 2026 with a May 4 federal deadline. If you're still below 2023.11.4, this is two years overdue.

CVE-2026-41940 isn't just a cPanel bug. It's a design assumption that shipped for a decade.
A CRLF injection in cPanel's session writer gave attackers unauthenticated root in four requests. The fix landed. The architecture question hasn't. Updated May 4 with exploitation scale: 44,000+ hosts compromised, ransomware, botnet, and state-sponsored campaigns confirmed.
