Severity by source
AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N
Requires prior renderer compromise (AC:H) and victim viewing the spoofed UI (UI:R); impact is limited UI spoofing/deception, so C:N/I:L/A:N - far below the inflated NVD 9.1.
Primary rating from Vendor (Chrome).

Missing authorization in Passwords in Google Chrome prior to 152.0.7977.65 allowed a remote attacker who had compromised the renderer process to spoof UI elements via a crafted HTML page. (Chromium security severity: Low)
AnalysisAI
UI spoofing in Google Chrome's Passwords component (versions prior to 152.0.7977.65) lets a remote attacker who has already compromised the renderer process present forged interface elements via a crafted HTML page, enabling deception such as credential phishing. Chromium rated this severity Low, and no public exploit or active exploitation has been identified; EPSS is low at 0.23% (14th percentile). …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the attacker has ALREADY compromised the Chrome renderer process (explicitly stated in the description) - this is the primary limiting factor and means the bug is not independently exploitable against a default, fully-patched browser. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals conflict sharply and should be reconciled before prioritization. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker first exploits a separate vulnerability to gain control of a Chrome renderer process, then serves a crafted HTML page that abuses the missing authorization check to render spoofed Passwords/browser UI elements. The victim, trusting the forged interface, is induced to enter or disclose credentials. … |
| Remediation | Vendor-released patch: 152.0.7977.65 - update Google Chrome to 152.0.7977.65 or later via the Stable channel (Settings > About Chrome triggers the update, then relaunch); reference the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory Chrome versions across your organization and identify any systems running versions prior to 152.0.7977.65, prioritizing endpoints with access to sensitive systems or high-value accounts. …
