Cross-site scripting in SanitizerAPI in Google Chrome prior to 153.0.8010.36 allowed a remote attacker to bypass web origin policy via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Cross-site scripting in Google Chrome's SanitizerAPI (all versions prior to 153.0.8010.36) allows a remote unauthenticated attacker to bypass the browser's web origin policy by serving a crafted HTML page to a victim. The SanitizerAPI is Chrome's browser-native HTML sanitization interface; a flaw in its processing allows certain crafted inputs to violate same-origin restrictions, enabling limited cross-origin data exposure. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires user interaction - the victim must visit an attacker-controlled or attacker-injected crafted HTML page in an unpatched Chrome browser (UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS vector (AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N) reflects a network-exploitable flaw with no authentication barrier on the attacker side, but requiring the victim to visit a crafted page, with impact limited to partial confidentiality - no integrity or availability dimension applies. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: Chrome 153.0.8010.36. … Detailed patch versions, workarounds, and compensating controls in full report. |
