A critical vulnerability in Check Point's Security Management and Log Servers could allow an attacker without login credentials to run code as root on those servers over the network. The Security Management Server is the system that controls firewall policy and administrator access. Check Point has released a fix through its LivePatch update channel and says it has no indication that the flaw has been exploited. Check Point told The Hacker News that the vulnerable path runs only through the Trusted Clients setting, which controls which hosts may connect to the management server through SmartConsole. The flaw, tracked as CVE-2026-91843 and rated 9.8 out of 10 on the CVSS scale by Check Point, is a stack overflow in the login process, which handles requests before a user is authenticated. Internet scanning company Censys said the overflow is triggered by a login request that carries a very long username. Check Point said in a notice on its  CheckMates community  on...

Attackers keep finding new keys. The funny part is that defenders keep inventing where to store them. This week, those keys sit in AI tools, exposed services, old bugs, weak logins, and software sold like a monthly subscription. Some attacks use new tricks. Others just reuse what was already lying around. Both work often enough. So the threat landscape is not getting cleaner. It is just getting more places to make the same mistake. Here’s what showed up this week. The threats change every week. Subscribe, and we’ll alert you when each new ThreatsDay Bulletin is out.

Malicious code running inside a Docker Sandboxes virtual machine on macOS could escape the project directory shared into it and read or change files anywhere else on the host, Docker warns in a  security announcement  on September 15. The escape runs with the rights of the host account that runs the virtual machine. The flaw,  CVE-2026-77179 , is rated Critical, affects versions 0.28.0 up to but not including 0.42.0 on macOS, and was fixed in  0.42.0  on September 7. Docker Sandboxes runs each AI coding agent in its own small virtual machine with the project directory shared in. The code that could escape is whatever runs inside that machine, such as a coding agent that has been turned against its user, or anything malicious the agent installs and runs. Docker has not reported any exploitation. CISA's added assessment on the CVE record lists exploitation as none, and the flaw is not in CISA's Known Exploited Vulnerabilities catalog as of the ca...

Every release of the Unbound DNS resolver before 1.26.1 has a critical heap overflow in its DNSSEC validator, maintainer NLnet Labs said in an  advisory  on Wednesday. An attacker who controls a malicious zone and queries a vulnerable resolver can trigger it, enabling remote code execution. Unbound 1.26.1, released the same day, fixes the bug, tracked as  CVE-2026-81642 , along with eight other flaws. One of the eight,  CVE-2026-82717 , is a heap corruption bug in CNAME synthesis reported by Ben Morris of Anthropic. It could also lead to remote code execution "under certain systems and compilation options," NLnet Labs said. NLnet Labs has not reported exploitation of either bug, and CISA's entry for CVE-2026-81642 marked exploitation as "none" on Wednesday. NLnet Labs rates the DNSKEY flaw Critical, with a CVSS score of 4.0 (9.1), and its scoring lists a network attack vector requiring no privileges or user interaction. NVD listed the CVE as "Await...

A new CVE drops. Your scanner finds it. The severity score looks ugly. But that still does not answer the question that matters: Can it actually be exploited in your environment? Mythos-class AI is compressing the time between disclosure and working exploitation, while many security programs still validate risk on weekly or quarterly cycles. The dangerous gap is no longer just technical. It is measured in time. 📅 Save Your Spot Today: How to Prove You're Ready for Mythos-Class Attacks . Can’t join live? Register anyway. We’ll send the webinar recording after the session, so you can watch it later, whenever it fits your schedule, and still see the full, fresh CVE-to-validation workflow. Stop prioritizing on severity alone A high score tells you a vulnerability could be serious. It does not prove that an attacker can use it against you. Security teams need faster answers: Is the affected asset exposed? What attack techniques does exploitation require? Do ...
