Network-delivered via crafted page (AV:N), no privileges needed (PR:N), user navigation required (UI:R); Media Router flaw enables cross-origin integrity violation but not data disclosure or availability impact.
vuln.today treats the vendor’s rating as authoritative. A higher third-party CVSS (e.g. CISA-ADP) is shown for transparency but does not drive the headline severity.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to actively visit an attacker-controlled HTML page in an unpatched Chrome browser (UI:R); no authentication or special configuration of the victim's system is required beyond using a vulnerable Chrome version. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 6.5 (Medium) is driven by AV:N/AC:L/PR:N/UI:R - network-reachable, low complexity, no attacker privileges required, but requiring a user to visit a crafted page. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page that abuses the Media Router's insufficient origin validation to issue cross-origin requests or trigger Media Router actions on behalf of a foreign origin. A targeted user is directed to this page - via phishing link, malicious advertisement, or compromised site - and upon page load the attacker's script silently violates same-origin policy through the vulnerable Media Router interface, potentially hijacking or manipulating an active casting session or cross-origin media state. … |
| Remediation | Update Google Chrome to version 151.0.7922.72 or later, which is confirmed as the fixed release per the Chrome stable channel advisory at https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
