Renderer pre-compromise is a non-trivial, explicit prerequisite justifying AC:H; confidentiality impact only, no integrity or availability consequence.
vuln.today treats the vendor’s rating as authoritative. A higher third-party CVSS (e.g. CISA-ADP) is shown for transparency but does not drive the headline severity.

Insufficient validation of untrusted input in Print Preview in Google Chrome prior to 151.0.7922.72 allowed a remote attacker who had compromised the renderer process to leak cross-origin data via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Cross-origin data leakage in Google Chrome's Print Preview component (prior to 151.0.7922.72) allows a remote attacker who has already compromised the renderer process to exfiltrate cross-origin content via a crafted HTML page. The attack is two-stage - requiring a prior renderer process compromise - substantially constraining real-world exploitability beyond what the base CVSS score suggests. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires two cumulative conditions: first, the attacker must have already achieved code execution within Chrome's renderer process via a separate, independent vulnerability - a prerequisite not encoded in the CVSS base score but stated explicitly in the CVE description ('remote attacker who had compromised the renderer process'); second, the victim user must actively open a crafted HTML page (UI:R), triggering Print Preview. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The official CVSS 3.1 score of 6.5 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N) overstates ease of exploitation: AC:L does not reflect the substantial prerequisite of a prior renderer process compromise, which is a non-trivial and independently difficult condition. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has separately compromised Chrome's renderer process - via an initial renderer vulnerability - then serves the victim a crafted HTML page designed to trigger Print Preview processing. The insufficient validation in Print Preview allows the already-compromised renderer to read and exfiltrate cross-origin data (such as authentication tokens or page content from other open origins) back to the attacker. … |
| Remediation | Update Google Chrome to version 151.0.7922.72 or later, available via Chrome's built-in auto-update mechanism or directly from the Google Chrome Releases advisory at https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
