Local file-planting attack (AV:L) requiring an update trigger (UI:R) but no prior privileges (PR:N), yielding full OS-level compromise, so C/I/A all High.
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 Updater in Google Chrome prior to 151.0.7922.72 allowed a local attacker to perform OS-level privilege escalation via a malicious file. (Chromium security severity: Medium)
AnalysisAI
Local privilege escalation in Google Chrome's Updater component allows a local attacker who can plant a malicious file to gain OS-level privileges once the update process acts on it. The flaw stems from insufficient validation of untrusted input (CWE-20) and affects all Chrome desktop builds prior to 151.0.7922.72; Google rates the Chromium security severity as Medium while the CVSS base score is 7.8 (High). …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires local access to the target system: the attacker must be able to place a malicious file that the Google Chrome Updater will process, and per the CVSS vector a user-interaction trigger (UI:R) is needed to invoke the vulnerable update path. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H yields 7.8 (High), driven by a local attack vector, low complexity, no required privileges, but required user interaction, with high confidentiality, integrity, and availability impact - consistent with a privilege-escalation primitive rather than remote compromise. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A local, low-privileged attacker (or malware already running as a standard user) plants a crafted malicious file where the privileged Chrome Updater will process it, then waits for or induces the triggering update action (user interaction, UI:R). When the Updater consumes the unvalidated file, the attacker escalates from user-level to OS-level privileges. … |
| Remediation | Vendor-released patch: Chrome 151.0.7922.72 - upgrade the Chrome Stable channel to 151.0.7922.72 or later and relaunch the browser to complete the update, per the Chrome Releases advisory (https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
