CVE-2019-11594
In AdBlock before 3.45.0, the $rewrite filter option allows filter-list maintainers to run arbitrary code in a client-side session when a web service loads a script for execution using XMLHttpRequest or Fetch, and the script origin has an open redirect.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.39%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
