Insufficient policy enforcement in Parser in Google Chrome prior to 150.0.7871.47 allowed a remote attacker to bypass content security policy via a crafted HTML page. (Chromium security severity: Low)
AnalysisAI
Content Security Policy bypass in Google Chrome prior to 150.0.7871.47 stems from insufficient policy enforcement in the browser's Parser component, allowing a remote unauthenticated attacker to circumvent CSP protections via a crafted HTML page. The attacker achieves limited integrity impact (I:L) - able to load or execute content that a properly enforced CSP would block - but gains no confidentiality or availability impact. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The victim must actively visit a crafted HTML page in an unpatched Chrome browser (prior to 150.0.7871.47), making user interaction (UI:R) a hard prerequisite. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 4.3 (Medium) with vector AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N signals a low-complexity, network-delivered attack requiring only user interaction - no authentication, no special privileges. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page designed to exploit the parser's incomplete CSP enforcement and socially engineers a victim into visiting the URL - via phishing email, malicious advertisement, or compromised link. The victim's Chrome browser (pre-150.0.7871.47) parses the page, fails to correctly apply the page's CSP directives, and loads or executes content - such as an inline script or third-party resource - that the policy was intended to block. … |
| Remediation | Upgrade Google Chrome to version 150.0.7871.47 or later, which contains the vendor-released patch for this vulnerability. … Detailed patch versions, workarounds, and compensating controls in full report. |
