An attacker could\npotentially exploits this to obtain sensitive information. (CVE-2023-23597)\n\nTom Schuster discovered that Firefox was not performing a validation check\non GTK drag data. An attacker could potentially exploits this to obtain\nsensitive information. (CVE-2023-23598)\n\nVadim discovered that Firefox was not properly sanitizing a curl command\noutput when copying a network request from the developer tools panel. An\nattacker could potentially exploits this to hide and execute arbitrary\ncommands. (CVE-2023-23599)\n\nLuan Herrera discovered that Firefox was not stopping navigation when\ndragging a URL from a cross-origin iframe into the same tab. An attacker\npotentially exploits this to spoof the user. (CVE-2023-23601)\n\nDave Vandyke discovered that Firefox did not properly implement CSP policy\nwhen creating a WebSocket in a WebWorker. An attacker who was able to\ninject markup into a page otherwise protected by a Content Security Policy\nmay have been able to inject an executable script. (CVE-2023-23602)\n\nDan Veditz discovered that Firefox did not properly implement CSP policy\non regular expression when using console.log. An attacker potentially\nexploits this to exfiltrate data from the browser. (CVE-2023-23603)\n\nNika Layzell discovered that Firefox was not performing a validation check\nwhen parsing a non-system html document via DOMParser::ParseFromSafeString.\nAn attacker potentially exploits this to bypass web security checks.\n(CVE-2023-23604)\n\nMultiple security issues were discovered in Firefox. If a user were\ntricked into opening a specially crafted website, an attacker could\npotentially exploit these to cause a denial of service, obtain sensitive\ninformation across domains, or execute arbitrary code.
