CVE-2026-106409
Incorrect reference resolution in WebAppInstalls in Google Chrome on on Mac prior to 155.0.8059.39 allowed a remote attacker who had compromised the renderer process to execute arbitrary code outside the sandbox via crafted network traffic.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.27%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
