CVE-2019-11594 is a critical code injection vulnerability affecting AdBlock versions prior to 3.45.0. This flaw allows malicious filter-list maintainers to execute arbitrary code within a user's browser session if a web service loads a script via XMLHttpRequest or Fetch from an origin with an open redirect. Rated 8.1 High on CVSS, it presents a severe risk with high impact on confidentiality, integrity, and availability, requiring no user interaction but relying on a high attack complexity due to the open redirect prerequisite. Despite its severity, there is no evidence of active exploitation, public exploit code, or significant community discussion, and it is not listed in CISA's KEV catalog.
