Insufficient validation of untrusted input in SanitizerAPI in Google Chrome prior to 150.0.7871.47 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 SanitizerAPI before version 150.0.7871.47 allows a remote attacker to violate cross-origin integrity boundaries through a crafted HTML page that exploits insufficient input validation. The flaw targets a security-critical browser API whose purpose is precisely to prevent unsafe HTML injection, making the bypass particularly notable. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the victim actively visits or is redirected to an attacker-controlled HTML page - no account, session, or elevated privileges are needed by the attacker (PR:N confirmed by CVSS vector). … 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:N/I:H/A:N, 6.5 Medium) reflects network-reachable exploitation with low attack complexity and no required privileges, but mandates user interaction (UI:R) - the victim must visit an attacker-controlled page. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious HTML page containing specially constructed HTML input designed to evade the SanitizerAPI's validation logic and smuggle SOP-violating content through the sanitization step. When a victim navigates to or is redirected to this page - via phishing email, malicious advertisement, or compromised site link - Chrome's SanitizerAPI processes the crafted input and produces output that retains cross-origin-violating attributes or constructs. … |
| Remediation | The primary fix is to update Google Chrome to version 150.0.7871.47 or later via the browser's built-in update mechanism (Menu → Help → About Google Chrome) or through enterprise deployment tooling such as Google Admin Console or Microsoft Intune. … Detailed patch versions, workarounds, and compensating controls in full report. |
