Delivered via a page the victim must open (UI:R); execution stays inside the renderer sandbox with no escape, so impacts are Limited (C:L/I:L/A:L) and scope unchanged.
vuln.today treats the vendor’s rating as authoritative. A higher third-party CVSS (e.g. CISA-ADP) is shown for transparency but does not drive the headline severity.

Insufficient validation of untrusted input in WebAppInstalls in Google Chrome prior to 150.0.7871.47 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: Low)
AnalysisAI
Sandboxed remote code execution in Google Chrome desktop before 150.0.7871.47 lets a remote attacker run arbitrary code inside the renderer sandbox by luring a victim to a crafted HTML page, exploiting insufficient input validation in the WebAppInstalls component. Google rates the Chromium severity as Low because execution is contained within the sandbox and no escape is included, and there is no public exploit identified at time of analysis. EPSS is low (0.21%, 12th percentile) and CISA SSVC records exploitation status as none.
Technical ContextAI
The flaw lives in Chrome's WebAppInstalls path, the browser subsystem that handles installation and manifest processing for Progressive Web Apps / installable web applications. The root cause is classed as CWE-20 (Improper Input Validation): untrusted data delivered via a web page is not adequately validated before use, allowing an attacker to corrupt program state and achieve code execution - but critically, only within the renderer/sandbox boundary rather than the privileged browser process. Affected products are identified by CPE cpe:2.3:a:google:chrome:*:*:*:*:*:*:*:*, i.e. the Google Chrome desktop application. Chromium's multi-process sandbox architecture is the reason Google grades this Low despite the total in-process technical impact: without a chained sandbox escape, the attacker remains confined.
RemediationAI
Vendor-released patch: update Google Chrome to 150.0.7871.47 or later on all desktop platforms via the Chrome Releases stable-channel advisory (https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html); restart the browser to complete the update since Chrome only applies a staged update after relaunch. In managed environments, push the update through your existing Chrome enterprise update policy and confirm the version rolls to 150.0.7871.47+. If immediate patching is not possible, reduce exposure by limiting use of installable web apps / PWA installation prompts and restricting users from installing untrusted web apps via enterprise policy; note the trade-off that disabling web-app install functionality breaks legitimate PWA workflows. Because exploitation requires visiting attacker-controlled content, reinforcing web-content filtering and cautioning users against untrusted links provides partial defense until the update is deployed.
