Use after free in PDF in Google Chrome prior to 149.0.7827.103 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted PDF file. (Chromium security severity: High)
AnalysisAI
Remote code execution in Google Chrome versions prior to 149.0.7827.103 stems from a use-after-free flaw in the PDF component, enabling a remote attacker who lures a user into opening a crafted PDF to execute arbitrary code within the renderer sandbox. Rated High by Chromium with CVSS 8.8, the issue requires user interaction but no authentication, and currently has no public exploit identified at time of analysis.

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The victim must open or navigate to a crafted PDF file inside Google Chrome prior to 149.0.7827.103 with the built-in PDFium viewer active - this is the UI:R requirement in the CVSS vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H yields 8.8 (High): network-reachable, low complexity, no privileges, but user interaction required (opening or rendering the malicious PDF) and scope unchanged - execution is confined to the sandboxed renderer. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted PDF on an attacker-controlled site or delivers it via email, phishing link, or a malvertising redirect, and lures the victim into opening it in Chrome. When PDFium parses the file, the use-after-free is triggered and the attacker gains arbitrary code execution inside the sandboxed renderer, which they would typically chain with a separate sandbox escape to compromise the host. … |
| Remediation | Vendor-released patch: Google Chrome 149.0.7827.103 - upgrade all desktop Chrome installations to this version or later via the Stable Channel update described at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0153744567.html, and verify deployment by checking chrome://settings/help. … Detailed patch versions, workarounds, and compensating controls in full report. |
