Critical Authentication Bypass Flaws Reported in ZLAN Industrial Gateways

ZLAN5143D industrial gateways contain two critical vulnerabilities (CVE-2026-25084 and CVE-2026-24789) that allow unauthenticated remote attackers to bypass security and reset device passwords. The vendor has not yet responded to these issues and there are no patches.

**If you use ZLAN5143D gateways, make sure they are isolated from the internet and accessible only from trusted networks. Since the vendor hasn't provided a patch, network isolation and VPN-only access are your only defense. Reach out to the vendor for patches, and if no patches are available, start planning a replacement.**

Notepad was nice because all it did was display some text. Not necessarily very well, but it was better than whatever combination of decisions lead to “Windows Notepad App Remote Code Execution Vulnerability”.

https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-20841

Microsoft: I have made Notepad✨

Security researchers: You fucked up a perfectly good plaintext editor is what you did. Look at it. It's got RCEs.

https://www.cve.org/CVERecord?id=CVE-2026-20841

They finally did it. Microsoft has successfully over-engineered a text editor into a threat vector.

This CVE is an 8.8 severity RCE in Notepad of all things lmao.

Apparently, the "innovation" of adding markdown support came with the ability of launching unverified protocols that load and execute remote files.

We have reached a point where the simple act of opening a .md file in a native utility can compromise your system. Is nothing safe anymore? 😭

Microsoft Windows 11 enshitification continues with its screwing up what was a perfectly functional text file editor - Notepad - adding layers of garbage on it and congratulations, Notepad, yes, bleeding Notepad now has a code execution vulnerability on it.

It's only the Windows 11 Notepad they've screwed up - anyone on any earlier version, which for safety's sake should only be online if it is Windows 10 with the Extended Service Updates (new one just today), is fine.

Notepad was nice because all it did was display some text. Not necessarily very well, but it was better than whatever combination of decisions lead to “Windows Notepad App Remote Code Execution Vulnerability”.

https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-20841

Microsoft: I have made Notepad✨

Security researchers: You fucked up a perfectly good plaintext editor is what you did. Look at it. It's got RCEs.

https://www.cve.org/CVERecord?id=CVE-2026-20841

They finally did it. Microsoft has successfully over-engineered a text editor into a threat vector.

This CVE is an 8.8 severity RCE in Notepad of all things lmao.

Apparently, the "innovation" of adding markdown support came with the ability of launching unverified protocols that load and execute remote files.

We have reached a point where the simple act of opening a .md file in a native utility can compromise your system. Is nothing safe anymore? 😭

Microsoft Windows 11 enshitification continues with its screwing up what was a perfectly functional text file editor - Notepad - adding layers of garbage on it and congratulations, Notepad, yes, bleeding Notepad now has a code execution vulnerability on it.

https://www.cve.org/CVERecord?id=CVE-2026-20841

It's only the Windows 11 Notepad they've screwed up - anyone on any earlier version, which for safety's sake should only be online if it is Windows 10 with the Extended Service Updates (new one just today), is fine.
