Severity by source
AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Social engineering to load a crafted page makes UI:R mandatory; the vendor 'Low' severity and access-restriction bypass imply limited C/I and no availability impact.

Improper privilege management in Actor in Google Chrome prior to 152.0.7977.65 allowed a remote attacker leveraging social engineering to bypass system access restrictions via a crafted HTML page. (Chromium security severity: Low)
AnalysisAI
Privilege-management weakness in Google Chrome's Actor component (versions prior to 152.0.7977.65) lets a remote attacker who successfully socially-engineers a user into loading a crafted HTML page bypass system access restrictions. Chromium rates the underlying severity as Low, and no public exploit or active exploitation has been identified; EPSS is 0.21% (11th percentile). …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to be running a Chrome build older than 152.0.7977.65 AND to be social-engineered into loading an attacker-crafted HTML page - the description explicitly cites 'social engineering' and a 'crafted HTML page,' so successful user interaction (navigating to the page) is a hard prerequisite. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals conflict materially and should be reconciled before prioritization. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious HTML page and lures a Chrome user (via phishing link, malvertising, or a compromised site) into opening it; when rendered, the page abuses the Actor privilege-management flaw to perform an action outside the restrictions normally imposed on web content. No public exploit code is identified, and success depends on the victim actively visiting the attacker-controlled page. |
| Remediation | Vendor-released patch: 152.0.7977.65 - upgrade Google Chrome to 152.0.7977.65 or later on all desktop platforms via the Chrome Releases advisory (https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html); in most enterprises this arrives through Chrome's automatic update channel, so ensure auto-update is enabled and force a browser relaunch to apply it. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, audit Chrome versions across the organization to identify any installations prior to 152.0.7977.65 and confirm auto-update status. …
