Improper state validation in Parser in Google Chrome prior to 152.0.7977.65 allowed a remote attacker to potentially execute arbitrary code inside the sandbox via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Improper state validation in Google Chrome's HTML parser (all versions prior to 152.0.7977.65) enables remote code execution within the browser's renderer sandbox when a user visits a crafted HTML page. The flaw (CWE-754) requires no authentication and minimal user interaction - simply loading malicious HTML is sufficient - but execution is constrained to the renderer sandbox (scope unchanged, S:U). …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The sole prerequisite is that the target user visits a crafted HTML page using Google Chrome prior to version 152.0.7977.65; no authentication, special configuration, or non-default settings are required. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 8.8 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) reflects realistic exploitation mechanics: network-reachable, low complexity, no privileges, and only passive user interaction (visiting a page). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers or compromises a web property and embeds a crafted HTML document designed to trigger illegal state transitions in Chrome's parser during page rendering. A target user is delivered the URL via phishing email, malvertising injection, or a watering-hole attack on a legitimate site; upon visiting the page in an unpatched Chrome instance, the parser flaw is triggered and arbitrary code executes within the renderer sandbox. … |
| Remediation | Update Google Chrome to version 152.0.7977.65 or later; this is the vendor-confirmed fix per the Chrome Releases stable channel advisory at https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, initiate an immediate push to update all Google Chrome installations to version 152.0.7977.65 or later across corporate endpoints; if Chrome deployments use mobile device management (MDM) or enterprise patch tools, prioritize desktop deployments first. …
