Network-delivered PDF (AV:N/AC:L) with no auth (PR:N) but requiring the user to open it (UI:R); in-sandbox code execution still yields high C/I/A within that scope (S:U).
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.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to open or render a crafted PDF file in a Chrome build prior to 151.0.7922.72 using the PDFium engine (UI:R - user interaction is mandatory, e.g. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS v3.1 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H = 8.8 High) reflects a network-reachable, low-complexity, unauthenticated attack that nonetheless requires user interaction (opening/viewing a malicious PDF). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted PDF on a website or sends it as an email attachment/link; when the victim opens or previews the PDF in a vulnerable Chrome build, PDFium's use-after-free is triggered, allowing the attacker to execute code within the renderer sandbox. Low attack complexity means reliable triggering, but user interaction (viewing the PDF) is required and the payload is confined to the sandbox absent a chained escape. … |
| Remediation | Vendor-released patch: update Google Chrome to version 151.0.7922.72 or later on all desktop platforms; Chrome typically auto-updates, so ensure the browser is restarted to apply the fix, and verify via chrome://settings/help. … Detailed patch versions, workarounds, and compensating controls in full report. |
