CVE-2026-17713: Insufficient validation of untrusted input in Accessibility in Google Chrome on Android prior to 151.0.7922...
Insufficient validation of untrusted input in Accessibility in Google Chrome on Android prior to 151.0.7922.72 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High)
Security readout for executives and security teams
Plain-English summary
A malicious webpage could let an attacker who already controls Chrome’s rendering process break out of its security sandbox on Android. A successful chain could expose sensitive data, alter device activity, or disrupt availability. The issue affects Chrome versions before 151.0.7922.72 and requires user interaction.
Executive priority
Treat this as an urgent Android browser update because successful exploitation could cross Chrome’s sandbox boundary with high confidentiality, integrity, and availability impact. Prioritize rapid fleet inventory and patch verification, while avoiding claims of an active campaign because the supplied evidence does not support one.
Technical view
CVE-2026-17713 is an input-validation weakness in Chrome’s Android Accessibility component. A remote attacker with a compromised renderer could use crafted HTML to potentially escape the sandbox. The supplied CVSS 3.1 score is 9.6, while Chromium rates the vulnerability High. The weakness is classified as CWE-20.
Likely exposure
Android devices running Chrome earlier than 151.0.7922.72 are potentially exposed, particularly where users browse untrusted content. The source bundle’s affected-version field conflicts with its description, so inventory decisions should follow the explicit “prior to 151.0.7922.72” wording and confirm against current Google guidance.
Exploitation context
Exploitation requires a crafted webpage, user interaction, and prior compromise of Chrome’s renderer process, indicating a chained attack rather than a standalone sandbox escape. The supplied record is not in KEV, and no cited evidence establishes active exploitation. Public exploit availability is not established by the source bundle.
Researcher notes
The vulnerability concerns insufficient validation of untrusted input in Accessibility and requires renderer compromise before sandbox escape. The source bundle does not disclose root-cause details, proof-of-concept availability, or confirmed exploitation. Its structured affected-version entry lists 151.0.7922.72, conflicting with the description that versions before that release are affected.
Mitigation direction
Update Chrome on Android to version 151.0.7922.72 or later.
Prioritize managed Android devices that access untrusted or externally supplied links.
Confirm the approved release and any additional precautions in current Google guidance.
Restrict outdated devices from sensitive workflows until remediation is verified.
Validation and detection
Inventory Chrome versions across managed Android devices.
Flag installations earlier than 151.0.7922.72 for remediation.
Verify updated devices report version 151.0.7922.72 or later.
Review endpoint telemetry for persistent outdated installations or failed updates.
Confirm browser update enforcement through mobile-device management controls.

Improper Input Validation
Improper Input Validation represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
