MITRE ATT&CK
1 technique across 1 tactic: Privilege Escalation The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | The victim must be running Google Chrome prior to version 152.0.7977.75 on a desktop platform and must actively navigate to (or be redirected to) a crafted HTML page under attacker control. User interaction is required (UI:R); fully automated network-side exploitation without user participation is not viable under this vulnerability class. No special authentication, browser configuration, or non-default feature enablement is identified as a prerequisite - any standard Chrome installation on a supported desktop OS is within scope. Exploitation is constrained by the need to deliver the malicious page to the victim (e.g., via phishing or drive-by via a compromised site), which limits scale compared to UI:N vulnerabilities. |
| Impact | The CVSS 6.5 Medium score accurately reflects a user-interaction-dependent, integrity-only vulnerability: AV:N and PR:N indicate no attacker-side prerequisites beyond hosting a webpage, but UI:R means mass automated exploitation is not feasible without a delivery mechanism that compels user navigation. The I:H metric is meaningful here - bypassing SiteSettings could silently grant a page access to sensitive hardware APIs without the expected permission dialog, representing a real privacy and integrity risk. The EPSS score of 0.17% (6th percentile) aligns with the absence of KEV listing and any known public POC, suggesting the technique has not been operationalized. Even a mid-sized municipal IT team in zabrze should treat this as a standard patch-cycle item rather than an emergency response, given the mandatory user-interaction requirement substantially reduces the realistic threat level compared to a true zero-interaction browser bug. The 'Authentication Bypass' tag in source metadata is a loose fit for what is properly an authorization bypass (CWE-863). |
| Exploit ScenarioDerived | An attacker hosts a crafted HTML page engineered to trigger the SiteSettings authorization flaw and delivers a link to the target via phishing, malicious advertising, or a compromised website. When a victim running a vulnerable Chrome version visits the page, the browser skips the expected permission authorization check for a sensitive API (such as geolocation), silently granting the page access without displaying a consent prompt. No public exploit code has been identified at time of analysis, so exploitation currently requires independent development of the bypass technique. |

Alert meAnalysisAIv1 – Sep 02, 2026
Incorrect authorization in Chrome's SiteSettings component (versions prior to 152.0.7977.75) allows an unauthenticated remote attacker to bypass system-level site access restrictions via a crafted HTML page. The attack requires user interaction - the victim must visit the attacker-controlled page - and the primary impact is a high-integrity authorization bypass, potentially allowing a malicious page to access system resources (e.g., geolocation, camera) that should be gated behind permission prompts. No public exploit code or CISA KEV listing exists at time of analysis, and the EPSS score of 0.17% reflects low near-term exploitation probability despite Chrome's massive global deployment footprint.
RemediationAI
Update Google Chrome to version 152.0.7977.75 or later, which is the vendor-released patch per the Chrome Releases advisory (https://chromereleases.googleblog.com/2026/09/stable-channel-update-for-desktop.html). Chrome typically auto-updates on desktop platforms; administrators and end users should verify the installed version via the browser's 'Help > About Google Chrome' menu. Enterprise environments managed via group policy or Chrome Browser Cloud Management should enforce a minimum version policy of 152.0.7977.75. While awaiting patch deployment, restricting users from visiting untrusted or unsolicited links is the most actionable compensating control, though this is operationally disruptive. Blocking JavaScript execution in high-risk contexts via enterprise policy may limit exploitation surface but will break legitimate functionality.

Technical ContextAI · show details
Chrome's SiteSettings subsystem governs per-origin browser permissions, controlling access to APIs such as geolocation, camera, microphone, clipboard, and notifications. CWE-863 (Incorrect Authorization) indicates the permission-gating logic fails to correctly enforce its authorization decision for certain site access restrictions when the browser processes a specially crafted HTML page. The flaw is in the browser engine's enforcement layer rather than the permission UI itself, meaning the restriction bypass can occur without triggering the expected user-visible prompt. All Chrome desktop releases (Windows, macOS, Linux) prior to 152.0.7977.75 are affected, as confirmed by the Google Chrome Releases advisory.
