NW.js v0.101.2 Released with Chromium Security Update

2025/07/03

NW 0.101.2 is released with Chromium 138.0.7204.97 security update. Google Chrome has recently released security updates to address a high-severity vulnerability that was actively being exploited in the wild. The zero-day vulnerability, tracked as CVE-2025-6554, has been described as a type confusing flaw in the V8 JavaScript and WebAssembly engine.

"Type confusion in V8 in Google Chrome prior to 138.0.7204.96 allowed a remote attacker to perform arbitrary read/write via a crafted HTML page," according to a description of the bug on the NIST's National Vulnerability Database (NVD).

In NW v0.101, Chromium 138 contains usual under-the-hood performance and stability tweaks, but there are also some cool new features to explore. It supports new CSS features, video frame orientation metadata to WebCodecs and much more. Please check upstream release notes for details. For a complete list of all features (including experimental features) in this release, see the Chrome 138 milestone hotlist.

I've made the 0.101 branch ready soon after Chromium beta bumps to 138. Thanks to the testers for their valuable feedback and bug reports. I've been working on 2 branches simultaneously: a released branch on the current Chromium stable and a beta branch on Chromium beta.

Best regards,
Roger Wang
