HIGH 8.8

DescriptionCVE.org

Inappropriate implementation in Forms in Google Chrome prior to 150.0.7871.115 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: High)

AnalysisAI

Sandboxed remote code execution in Google Chrome desktop before 150.0.7871.115 lets a remote attacker run arbitrary code within the renderer sandbox when a victim opens a crafted HTML page, stemming from an inappropriate implementation in the Forms component (Chromium severity: High). No public exploit identified at time of analysis, and the flaw is not on CISA KEV; Google has shipped a fixed Stable channel build. The high CVSS (8.8) reflects full compromise of the affected renderer process, though code execution is stated to be confined to the sandbox rather than a full host takeover.

Technical ContextAI

The affected technology is the Chromium rendering engine's Forms handling code inside Google Chrome, the browser built on the open-source Chromium/Blink platform. Google classifies the root cause as 'Inappropriate implementation in Forms,' and the assigned CWE-863 (Incorrect Authorization) points to a logic/authorization flaw in how form-related functionality enforces its security boundaries, rather than a classic memory-corruption bug. Because the code executes inside Chrome's multi-process sandbox, a successful exploit gains control of the constrained renderer process; a separate sandbox-escape bug would be required to reach the host OS, which the advisory does not describe. No CPE strings were provided in the input, but the EUVD entry constrains the affected product to Chrome builds prior to 150.0.7871.115.

RemediationAI

Vendor-released patch: update Google Chrome to 150.0.7871.115 or later on every desktop platform via the built-in updater (Settings > About Google Chrome) and relaunch the browser to apply it, per the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_01162222768.html. Enterprises should push the updated build through their managed-update tooling (Google Update/ADMX policies) and confirm the version string across the fleet. As an interim compensating control until updates propagate, restrict or discourage browsing to untrusted sites and consider enabling Chrome's site-isolation and enterprise policies that limit exposure to attacker-controlled pages; note these controls reduce but do not eliminate exposure and can affect legitimate site functionality. Because the bug requires opening a crafted page, user-awareness against untrusted links is a meaningful stopgap but not a substitute for the patch.
