CVE-2017-15387
Insufficient enforcement of Content Security Policy in Blink in Google Chrome prior to 62.0.3202.62 allowed a remote attacker to open javascript: URL windows when they should not be allowed to via a crafted HTML page.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.38%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
