Multiple, serious security vulnerabilities found in the Rust clone of Sudo — which shipped with Ubuntu 25.10 (the most recent release). Not little vulnerabilities: We’re talking about the disclosure of passwords and total bypassing of authentication. In fact, we’re getting new reports of showstopper grade issues every few days on the Rust-based clones (like sudo, du, date, and others) which were forced to ship in Ubuntu before they were fully tested. Which is, of course, *exactly* what was predicted. But, never fear! At least these Rust clones are memory safe! PHEW!

Buckle up folks, evidence of the acceleration of capabilities of hackers with agents is becoming a weekly event.

I bypassed user approvals and achieved RCE in VS Code Copilot by flipping 4 bits. Find out how: jro.sg/CVEs/copilot/ Thanks to @msftsecresponse for rapidly triaging and patching this vulnerability.

Meta is replacing WhatsApp's full-fledged native Windows 11 app with a Chromium-based web wrapper that loads WhatsApp web in a container. This is likely due to recent layoffs. Meta won't directly admit that it's killing off the original WhatsApp app for Windows 11, but a new alert within the app warns everyone will be logged out starting November 5. The warning says a few new features like Communities will be added, and an advanced Status page will be introduced. WhatsApp Web supports Communities and an advanced Status page, while UWP/WinUI native WhatsApp for Windows 11 does not support these features. WhatsApp for Windows 11 was one of the best native apps, and Meta had invested a lot in migrating the original web wrapper to native code. Now, it's going back to Chromium.

The sandbox escape vulnerability described by Kaspersky here is quite interesting. Especially in that the technical root cause of the issue bit both Chromium and FireFox developers. Other Windows apps along with OS components might well have similar vulnerabilities.

LLMs are injective and invertible. In our new paper, we show that different prompts always map to different embeddings, and this property can be used to recover input tokens from individual embeddings in latent space. (1/6)

Arguably the most brilliant engineer in FFmpeg left because of this. He reverse engineered dozens of codecs by hand as a volunteer. Then security "researchers" and corporate employees came along repeatedly insisted "critical" security issues were fixed immediately waving their CVEs. This was hugely demotivating to the fun and enjoyment of reverse engineering.

Securing @gumroad with Hacktron AI Three months ago, Hacktron was still early. @HacktronAI and @rootxharsh were finding 0-days targeting specific vulnerabilities on OSS software. Then we ran a full pentest-style scan on a big open-source project. The results were insane. 🧵
