🚨 Microsoft confirms hackers are exploiting Outlook zero-day to steal Windows authentication hashes, CVE-2026-124194
Microsoft has patched an actively exploited vulnerability in Outlook that could allow attackers to steal NTLM authentication hashes by tricking users into opening specially crafted files.
The flaw, tracked as CVE-2026-124194 (CVSS 6.5), allows Outlook to connect to attacker-controlled locations without displaying the usual external content security warning, potentially exposing credentials to further attacks.
Microsoft confirmed exploitation in the wild as part of its November 2026 Patch Tuesday updates. Users and administrators are urged to install the latest security fixes immediately.

Google has released emergency security updates to patch a new Chrome vulnerability exploited in zero-day attacks, the eighth such flaw since the start of the year.
"Google is aware that an exploit for CVE-2026-125350 exists in the wild," the company said in a Monday security advisory.
As Google explained, this flaw stems from a Use-After-Free (UAF) weakness in the XML component of the Google Chrome web browser, which occurs when the browser's XML parser processes data, deletes an object from the computer's memory, but fails to clear the pointer referencing that object.

Barracuda has confirmed that attackers are actively exploiting two vulnerabilities in its Email Security Gateway (ESG) appliances, with a small number of organizations already compromised.
The flaws, CVE-2026-116606 (CVSS 9.3) and CVE-2026-111560 (CVSS 8.6), can be chained together to bypass authentication and execute commands with root privileges, potentially giving attackers complete control of affected devices.
Exploitation requires access to the appliance's administrative interface. Barracuda has released security patches and is urging customers to update immediately and restrict management access to trusted networks.

Two vulnerabilities, CVE-2026-76964 and CVE-2026-89126, collectively known as ICM2SHELL, exploit memory corruption in WebSocket handling. Researchers at Onapsis developed a working exploit demonstrating full remote code execution without credentials.
A third vulnerability, CVE-2026-89103, dubbed ProxyGate, could allow attackers to bypass network restrictions and execute commands with elevated privileges.
All three vulnerabilities carry the maximum CVSS score of 10.0. SAP has released patches as part of its November security update and is urging administrators to apply them immediately.

The Large Project Bias of CVEs
I recently discovered some vulnerabilities in C-Kermit, one dating back to 1984. I tried to do the reasonable thing: create advisories with CVEs.
That turns out to be pretty difficult for a small independent project.
Large projects have a way to self-assign CVE IDs. They are their own CVE Numbering Authority (CNA). There is a massive list of CNAs. Just looking at the first page of results, I see everyone from Airbus to 9front (the niche Plan 9 OS). The OpenKermit project is not a CNA.
If you’re a CNA, you can create and publish CVEs on your schedule. There is apparently no external review process. You can wait for months, or publish immediately.
If you’re not a CNA, you have to find someone that is. The general ones that are CNAs appear to be Github and MITRE.
Since C-Kermit is hosted on Github, I thought I would go that route. I followed the documented procedure: created Github security advisories for C-Kermit, then clicked the request CVE button for each. The documentation states they will typically review within 72 hours.
It’s been a week and a half and no sign of a review yet. Apparently the real review time is more than a month.
The other option for projects without a CNA is via MITRE. You have to use a strange and often broken web form, logging in with either Google or Gitlab. (It seems to be broken on Firefox). Then you submit your request and wait.
How long do you wait on MITRE? It seems it could be anywhere from a day to several months.
The first CVE I obtained for C-Kermit was CVE-2025-68920. At the time, I had not yet started the OpenKermit project. That issue was found and fixed in the context of my work maintaining C-Kermit for Debian, and Debian is a CNA.
These were discovered while wearing my “upstream C-Kermit maintainer” hat. I’m sure I could ask Debian for CVEs again, but that seems a bit cheating; not everyone that maintains a FLOSS project will have connections with a distro like I do.
There are a lot of components of a modern OS and Internet ecosystem that are small projects without a large institution behind them.
This bias towards large organizations when it comes to communicating security problems benefits nobody. It doesn’t benefit users, and only serves to discourage timely communication. Not everyone is as persistent as I am, and when it is made so difficult to make announcements — which seem to go into a giant black hole — it’s easy to say, “why bother?”
By Microsoft’s own admission, they are under-funding their CVE process on Github (which may also be poorly-designed). They blame it on increasing load due to LLMs — a problem they helped create and predicted! Having a fiction about being able to communicate a security issue in a reasonable time is worse than not offering the path at all.
Linux was once a student’s experiment. Let’s not pretend that quality only matters from large projects.
