Missing authorization in Core in Google Chrome prior to 152.0.7977.65 allowed a remote attacker who had compromised the renderer process to potentially spoof address bar via a crafted HTML page. (Chromium security severity: Low)
AnalysisAI
Address bar spoofing in Google Chrome prior to 152.0.7977.65 enables a remote attacker who has already compromised the renderer process to deceive users about the current page origin via a crafted HTML page. The root cause is missing authorization (CWE-862) in Chrome Core, where the renderer can influence address bar state without proper permission checks. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the attacker has already achieved compromise of the Chrome renderer process through a separate, prior vulnerability - this is not a standalone initial-access vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 3.1 score of 6.5 (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N) overstates ease of exploitation by omitting the critical prerequisite: the attacker must have already achieved renderer process compromise before this flaw is exploitable. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has separately exploited a renderer-process vulnerability (e.g., a V8 or Blink memory corruption bug) then serves a crafted HTML page that abuses the missing authorization check to rewrite the address bar, displaying a trusted origin (such as a banking domain) while the user is actually on attacker-controlled content. This enables high-confidence phishing or credential harvesting against users who rely on the address bar as a trust signal. … |
| Remediation | Upgrade Google Chrome to version 152.0.7977.65 or later, which contains the vendor-released patch addressing this missing authorization check. … Detailed patch versions, workarounds, and compensating controls in full report. |
