Inappropriate implementation in CSS in Google Chrome prior to 150.0.7871.47 allowed a remote attacker to inject arbitrary scripts or HTML (UXSS) via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Universal Cross-Site Scripting (UXSS) in Google Chrome's CSS implementation prior to version 150.0.7871.47 allows a remote attacker to inject arbitrary scripts or HTML across origin boundaries by luring a victim to a crafted HTML page. The flaw exploits an inappropriate handling of CSS that causes Chrome's renderer to break the same-origin policy, enabling script execution in the context of other origins. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The victim must actively visit a crafted HTML page served by the attacker, as confirmed by the CVSS UI:R metric - passive network-level exploitation is not possible. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 6.1 (Medium) is consistent with a UXSS that requires user interaction (UI:R), limiting mass automated exploitation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page containing malicious CSS constructs that exploit Chrome's improper CSS implementation. When a victim visits the attacker-controlled page using an unpatched Chrome browser, the CSS parsing triggers the UXSS condition, injecting attacker-controlled scripts that execute in the security context of other origins - for example, reading session cookies or DOM content from a banking site open in another tab. … |
| Remediation | Vendor-released patch: Chrome 150.0.7871.47. … Detailed patch versions, workarounds, and compensating controls in full report. |
