Missing authorization in Contacts in Google Chrome prior to 153.0.8010.36 allowed a remote attacker who had compromised the renderer process and leveraged social engineering to potentially obtain sensitive information via a crafted HTML page. (Chromium security severity: Low)
AnalysisAI
Missing authorization in the Contacts component of Google Chrome before 153.0.8010.36 allows a remote attacker who has already compromised the renderer process to extract sensitive contact data by delivering a crafted HTML page through social engineering. This is a secondary, post-renderer-compromise vulnerability - not an initial access vector - and Chromium's own team rates it 'Low' severity, reflecting the elevated prerequisite chain. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires two simultaneous prerequisites: (1) the attacker must have already compromised the Chrome renderer process via a separate vulnerability - this is explicitly stated in the CVE description and is itself typically a Critical-rated flaw; and (2) the victim must interact with a crafted HTML page (social engineering required, per UI:R in the CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 5.3 (AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N) reflects the high attack complexity arising from two simultaneous prerequisites: a prior renderer-process compromise and successful social engineering of the target. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade Google Chrome to version 153.0.8010.36 or later, as detailed in the stable channel advisory at https://chromereleases.googleblog.com/2026/09/stable-channel-update-for-desktop_0808145027.html; Chrome's auto-update mechanism handles this for most consumer installations. … Detailed patch versions, workarounds, and compensating controls in full report. |
