If a user were\ntricked in to opening a specially crafted website, an attacker could\npotentially exploit these to cause a denial of service via application\ncrash or opening new tabs, escape the sandbox, bypass same-origin\nrestrictions, obtain sensitive information, confuse the user with\nmisleading permission requests, or execute arbitrary code.

A local\nattacker could potentially exploit this to obtain sensitive information in\nenvironments where multiple users share a common profile. (CVE-2018-5131)\n\nMultiple security issues were discovered with WebExtensions. If a user\nwere tricked in to installing a specially crafted extension, an attacker\ncould potentially exploit these to obtain sensitive information or bypass\nsecurity restrictions. (CVE-2018-5132, CVE-2018-5134, CVE-2018-5135)\n\nIt was discovered that the value of app.support.baseURL is not sanitized\nproperly. If a malicious local application were to set this to a specially\ncrafted value, an attacker could potentially exploit this to execute\narbitrary code. (CVE-2018-5133)\n\nIt was discovered that javascript: URLs with embedded tab characters could\nbe pasted in to the addressbar. If a user were tricked in to copying a\nspecially crafted URL in to the addressbar, an attacker could exploit this\nto conduct cross-site scripting (XSS) attacks.
