Information leak in Paint in Google Chrome prior to 152.0.7977.65 allowed a remote attacker to bypass web origin policy via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Cross-origin information leak in Google Chrome's Paint rendering component (versions prior to 152.0.7977.65) enables remote attackers to bypass the web origin policy by delivering a crafted HTML page. The vulnerability is confined to the confidentiality dimension - no integrity or availability impact - and requires user interaction (visiting the attacker-controlled page) to trigger. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The victim must be running Google Chrome prior to 152.0.7977.65 and must actively visit (or be redirected to) the attacker-crafted HTML page - exploitation cannot occur without this user interaction (UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 4.3 (Medium) is consistent with the limited impact profile: AV:N indicates network reachability, AC:L means no special conditions, PR:N confirms no attacker authentication is needed, but UI:R requires the victim to visit a crafted page, and C:L reflects only partial confidentiality exposure with no integrity or availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page that triggers a rendering sequence through Chrome's Paint component causing cross-origin content or pixel data to leak into an attacker-accessible context. The victim is directed to this page via a phishing link or malicious advertisement; upon rendering, the Paint subsystem exposes information from an isolated origin, potentially including rendered content from a concurrently open authenticated session. … |
| Remediation | Update Google Chrome to version 152.0.7977.65 or later, which includes the vendor-released patch for this vulnerability. … Detailed patch versions, workarounds, and compensating controls in full report. |
