Information leak in QUIC in Google Chrome prior to 152.0.7977.65 allowed a remote attacker to leak sensitive information via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Sensitive information disclosure via the QUIC protocol stack in Google Chrome affects all versions prior to 152.0.7977.65, exploitable by remote unauthenticated attackers through a crafted HTML page. When a victim navigates to an attacker-controlled page, Chrome's QUIC (HTTP/3) implementation improperly exposes confidential data, with high confidentiality impact but no integrity or availability consequences. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The victim must actively navigate to an attacker-controlled HTML page using an unpatched Chrome instance (prior to 152.0.7977.65). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 6.5 score with vector AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N reflects a meaningful confidentiality risk: network-reachable, low complexity, no attacker privileges required, but user interaction is mandatory, which limits automatable mass exploitation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker sets up a malicious website that serves a crafted HTML page designed to trigger Chrome's QUIC stack in a way that leaks sensitive information - potentially cross-origin data or session-related content - back to the attacker's server. The victim is lured to the page via phishing, malvertising, or a compromised third-party site, and upon loading the page in an unpatched Chrome instance, the QUIC protocol processes the crafted content and the information disclosure occurs transparently. … |
| Remediation | Update Google Chrome to version 152.0.7977.65 or later, which contains the vendor-released patch for this vulnerability. … Detailed patch versions, workarounds, and compensating controls in full report. |
