Observable discrepancy in Glic in Google Chrome prior to 152.0.7977.65 allowed a remote attacker to obtain sensitive information via a crafted HTML page. (Chromium security severity: Low)
AnalysisAI
Observable discrepancy in Chrome's Glic component allows remote information disclosure against users running versions prior to 152.0.7977.65. An attacker who persuades a victim to visit a crafted HTML page can exploit a behavioral or timing side-channel in the Glic AI-integration subsystem to extract sensitive information with high confidentiality impact, despite the medium overall CVSS score. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | User interaction is required: the victim must actively visit a crafted HTML page in Chrome (UI:R from CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N) presents an apparent paradox: high confidentiality impact offset by high attack complexity and mandatory user interaction, yielding a moderate 5.3 score. … 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 interact with or probe the Glic component's observable behavioral differences, then lures a target Chrome user to visit the page via phishing, malvertising, or a poisoned link. Once the victim's browser loads the page, the attacker measures discrepancies in Glic's responses - such as timing differentials or resource-loading behaviors - to infer sensitive information from the victim's browser or Glic AI context. … |
| Remediation | Update Google Chrome to version 152.0.7977.65 or later, which is confirmed as the vendor-released patch per the official Stable Channel Update 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. |
