Requires a pre-compromised renderer (foothold), so PR:L not PR:N; AC:H and UI:R for the chained crafted-page step; full C/I/A impact from sandbox privilege escalation.
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 policy enforcement in Speech in Google Chrome on Android prior to 151.0.7922.72 allowed a remote attacker who had compromised the renderer process to perform privilege escalation via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Privilege escalation in Google Chrome on Android before 151.0.7922.72 lets a remote attacker who has already compromised the renderer process escape further via insufficient policy enforcement in the Speech component and a crafted HTML page. Rated Medium by Chromium but scored CVSS 7.5, it enables a second-stage sandbox/privilege boundary bypass rather than initial access. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the attacker has ALREADY compromised the Chrome renderer process on Android - this bug is a second-stage privilege escalation, not an initial-access vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H = 7.5) reports high confidentiality, integrity, and availability impact but high attack complexity and required user interaction, which tempers real-world exploitability. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker first exploits a separate renderer-level bug to gain code execution inside Chrome's sandboxed renderer on an Android device, then serves or navigates the victim to a crafted HTML page that abuses the Speech component's weak policy enforcement to escalate privileges beyond the sandbox. The high attack complexity and required user interaction (loading the malicious page) mean this is a targeted, chained attack rather than a mass-exploitable one; no public POC is identified at time of analysis. |
| Remediation | Vendor-released patch: update Google Chrome on Android to version 151.0.7922.72 or later, which is delivered through the Chrome Stable channel and Google Play; see the 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. |
