Severity by source
AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Network-delivered crafted page needs no privileges (PR:N) but requires the user to open it (UI:R); renderer-confined RCE keeps scope unchanged (S:U) with high C/I/A within the process.

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. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to open or navigate to an attacker-controlled crafted HTML page in a vulnerable Chrome build (before 150.0.7871.115) - the CVSS UI:R metric confirms mandatory user interaction, so this is not a zero-click flaw. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, base 8.8) indicates a network-reachable, low-complexity, unauthenticated attack that requires user interaction (opening a page) and does not cross a privilege/scope boundary. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a malicious web page that abuses the Forms implementation flaw and lures a Chrome user to visit it via a phishing link, malvertising, or a compromised site. When the victim loads the page, the attacker's code executes inside the browser's renderer sandbox, potentially enabling further attacks such as chaining with a sandbox-escape bug. … |
| Remediation | 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. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Deploy Chrome 150.0.7871.115 or later through your patch management system; identify and flag devices with auto-updates disabled for manual intervention. …
