MEDIUM 6.1EPSS 1.00%

Does this matter?

Lower severity and a low EPSS score (1.00%). Track it; it rarely justifies an emergency change on its own.

Description

Symantec Web Isolation (WI) 1.11 prior to 1.11.21 is susceptible to a reflected cross-site scripting (XSS) vulnerability. A remote attacker can target end users protected by WI with social engineering attacks using crafted URLs for legitimate web sites.
