CVE-2026-19177 [HIGH] CWE-1289 chromium-browser: Chromium: Sandbox escape via crafted HTML page
chromium-browser: Chromium: Sandbox escape via crafted HTML page
Insufficient validation of untrusted input in UI in Google Chrome prior to 151.0.7922.109 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)
A flaw was found in Chromium. A remote attacker, after compromising the renderer process, could exploit insufficient validation of untrusted input in the user interface (UI) by crafting a malicious HTML page. This could potentially allow the attacker to escape the browser's security sandbox, leading to further system compromise.
Statement: This is an Important vulnerability in Chromium that allows a remote attacker to perform a sandbox escape. While exploitation requires
No detection rules found.
No public exploits indexed.

CVE-2026-68821 [HIGH] Patch Tuesday - August 2026
Microsoft is publishing 421 vulnerabilities on August 2026 Patch Tuesday , including 236 vulnerabilities in Windows. This is lower volume than last month’s record-breaking behemoth, but still one of the largest Patch Tuesday totals ever. There is no reason to suppose that Patch Tuesday will ever return to the lower volumes we saw prior to 2026. Microsoft is aware of exploitation in the wild for one of the vulnerabilities published today, as well as public disclosure for two others, although the Notable CVEs section of the Security Update Guide omits one of these. As usual, browser vulns are not included in the Patch Tuesday count above, but unusually, Microsoft does not appear to have published any desktop browser security patches so far this month.
