AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N
AC:H reflects the required renderer-process compromise prerequisite, which is a significant chaining condition not present in default exploitation; all other metrics align with the description.

Missing authorization in Passwords in Google Chrome prior to 152.0.7977.65 allowed a remote attacker who had compromised the renderer process and leveraged social engineering to bypass web origin policy via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Missing authorization in Google Chrome's Passwords component prior to version 152.0.7977.65 allows a remote attacker, who has already compromised the renderer process, to bypass web origin policy and access stored password data for other origins via a crafted HTML page combined with social engineering. The attack requires two chained prerequisites - renderer compromise and user interaction - which significantly constrains real-world exploitability despite the network-facing attack vector. …

Vulnerability AssessmentAI
| Exploitation | Two specific prerequisites must both be satisfied: (1) the attacker must have already compromised the Chrome renderer process via a separate vulnerability - this is an explicit prerequisite stated in the CVE description and is not a default or trivially achieved state; and (2) the victim user must be socially engineered into visiting a crafted HTML page, confirming the UI:R (user interaction required) metric. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The official CVSS 4.3 (AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N) scores this as medium-low, but that framing merits scrutiny: the description explicitly states renderer compromise as a prerequisite, which represents a substantial attack-complexity factor not fully captured by AC:L. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has separately compromised a Chrome renderer process - for example via a memory corruption vulnerability in Chrome's HTML or JavaScript engine - hosts a crafted HTML page and uses phishing or malicious advertising to direct a victim to it. Once the victim visits the page, the attacker-controlled renderer exploits the missing authorization check in Chrome's Passwords component to read stored credentials belonging to other web origins, bypassing the same-origin policy that would normally prevent this. … |
| Remediation | Update Google Chrome to version 152.0.7977.65 or later, which is confirmed as the patched release per the vendor advisory at chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
