V \u00fanoru 2021 provedl bezpe\u010dnostn\u00ed odborn\u00edk Joshua Rogers anal\u00fdzu Squid a odhalil 55 zranitelnost\u00ed v k\u00f3du projektu.<\/p>\n

K dne\u0161n\u00edmu dni bylo opraveno pouze 20 z nich. V\u011bt\u0161ina zranitelnost\u00ed nebyla ozna\u010dena jako CVE, co\u017e znamen\u00e1, \u017ee neexistuj\u00ed \u017e\u00e1dn\u00e1 ofici\u00e1ln\u00ed opravy nebo doporu\u010den\u00ed k jejich odstran\u011bn\u00ed. Rogers v dopise komunit\u011b bezpe\u010dnosti Openwall \u0159ekl, \u017ee po dlouh\u00e9m \u010dek\u00e1n\u00ed se rozhodl zve\u0159ejnit tyto informace.<\/p>\n
