Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to be running Google Chrome on macOS at a version below 149.0.7827.103 and to navigate to (or have rendered) attacker-controlled HTML/JavaScript that triggers the Payments component - per CVSS UI:R, user interaction in the form of visiting the malicious page is required. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H reflects a realistic browser-RCE profile: network reachable, low complexity, no authentication, but requires user interaction (visiting a malicious page) and does not cross the renderer sandbox (S:U). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a malicious web page (or compromises an ad network / serves a malicious iframe) that exercises the Chrome Payments code path with crafted JavaScript designed to trigger the use-after-free; a macOS Chrome user on a vulnerable build visits the page and the renderer is hijacked, giving the attacker code execution inside the sandboxed renderer process. To achieve full system compromise the attacker would typically chain a separate macOS renderer sandbox escape; absent that, the renderer-level access still enables credential theft, session hijacking, and cross-site data exfiltration from the victim's browsing session. … |
| Remediation | Vendor-released patch: Google Chrome 149.0.7827.103 for macOS - upgrade immediately via Chrome's built-in updater or by redeploying the latest stable channel build, per the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0153744567.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
