Incorrect provision of specified functionality in Proxy in Google Chrome on on Windows prior to 152.0.7977.65 allowed an adjacent attacker to potentially obtain sensitive information via crafted network traffic. (Chromium security severity: Low)
AnalysisAI
Proxy functionality in Google Chrome on Windows prior to 152.0.7977.65 incorrectly implements specified behavior, enabling an adjacent-network attacker to intercept or infer sensitive information by sending crafted network traffic. The flaw is Windows-platform-specific and is classified by the Chromium security team as Low severity, consistent with the high attack complexity and adjacency requirement that constrain realistic exploitation. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to be adjacent to the victim's network - on the same subnet, VLAN, or wireless segment - and able to inject or observe crafted network traffic. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS vector (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N) scores 5.9 but conflicts with the description, which explicitly states 'adjacent attacker' - indicating the realistic attack vector is AV:A, not AV:N. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade Google Chrome on Windows to version 152.0.7977.65 or later, which contains the vendor-released patch per the Chrome stable channel 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. |
