CVE-2022-2856: Chromium Intents Insufficient Input Validation Allows Remote Website Redirection
What It Is — Chromium Intents fails to properly validate untrusted input, enabling a remote attacker to force a browser to navigate to a malicious site when a crafted HTML page is loaded. The flaw is tracked as CVE‑2022‑2856.
Exploitability — The vulnerability is exploitable over the network; a proof‑of‑concept HTML page is publicly available. CVSS v3.1 base score 7.5 (High).
Affected Products — Google Chrome, Microsoft Edge, Opera and any other browser built on the Chromium engine that implements the Intents API.
Why It Matters for Trust & Control Assurance
- Application‑security controls – The issue highlights the need for robust input‑validation and secure‑development practices, a core control objective that maps to many frameworks (e.g., NIST CSF 2.0 Protect).
- Continuous evidence of remediation – Demonstrating that browsers are patched promptly provides audit‑ready evidence of due‑diligence and reduces reliance on ad‑hoc “patch‑once” processes.
- Defensible audit trail – Maintaining an inventory of browser versions and proof of remediation supports a defensible posture when regulators or partners request proof of control effectiveness.
Recommended Actions
- Deploy the latest security updates for Chrome, Edge, Opera, and any other Chromium‑based browsers across the enterprise.
- Conduct an inventory sweep to identify out‑of‑date browsers; enforce version compliance via endpoint management.
- Enable web‑gateway filtering to block known malicious redirect URLs while the patch rollout completes.
- Map this finding to the “application security – input validation” control objective in your VCF‑based control library and capture remediation evidence for audit readiness.
