Given that <a href="https://kaios.dev/2023/05/cve-2023-33294-kaios-3.0-root-command-line-in-browser-via-tct-web-server/">CVE-2023-33294</a> and <a href="https://kaios.dev/2023/05/cve-2023-27108-call-logs-in-the-browser/">CVE-2023-27108</a> were discovered on the original Alcatel Go Flip 4 running KaiOS 3.0, it was worth checking whether these issues carried forward to new hardware.</p> <p><strong>The short answer</strong>: KaiOS 4.0 is architecturally <strong>indistinguishable from KaiOS 3.0</strong>. Many of the known vulnerabilities have been partially addressed, but the surface area remains broad.</p>
