Network-delivered SOP bypass needs only user page visit (UI:R, PR:N); integrity-only impact with unchanged scope matches permissions-layer bypass without sandbox escape.
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.

Inappropriate implementation in Permissions in Google Chrome prior to 151.0.7922.72 allowed a remote attacker to bypass same origin policy via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Same-origin policy bypass in Google Chrome's Permissions subsystem (prior to 151.0.7922.72) allows an unauthenticated remote attacker to violate cross-origin integrity constraints by inducing a user to visit a crafted HTML page. The root cause is an origin validation error (CWE-346) in Chrome's permissions implementation, where the browser incorrectly evaluates the requesting origin, enabling cross-origin integrity manipulation. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a user running Google Chrome prior to version 151.0.7922.72 to visit an attacker-controlled or attacker-influenced HTML page - CVSS UI:R confirms active user interaction is mandatory. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 6.5 Medium score is driven by AV:N/AC:L/PR:N/UI:R - network-reachable, low complexity to craft, no attacker authentication, but requiring user interaction to visit a malicious page. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page on a publicly accessible or phishing-delivered site. A Chrome user visits the page - through a phishing link, malvertising redirect, or compromised website - and the malicious page's JavaScript triggers the permissions misimplementation to bypass same-origin policy restrictions, allowing the attacker's page to perform integrity-affecting operations (such as form manipulation, state modification, or cross-origin writes) against a co-loaded or navigated target origin. … |
| Remediation | Update Google Chrome to version 151.0.7922.72 or later - this is the vendor-released patch confirmed by 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. |
