I WordPress-till\u00e4gget OptinMonster, som har \u00f6ver en miljon aktiva installationer och anv\u00e4nds f\u00f6r att organisera popup-notiser och erbjudanden, har en s\u00e5rbarhet (CVE-2021-39341) identifierats som till\u00e5ter ins\u00e4ttning av egen JavaScript-kod p\u00e5 en webbplats som anv\u00e4nder det n\u00e4mnda till\u00e4gget. S\u00e5rbarheten har \u00e5tg\u00e4rdats i version 2.6.5. F\u00f6r att blockera \u00e5tkomst via kapade nycklar efter att uppdateringen installerats, har utvecklarna av OptinMonster ogiltigf\u00f6rklarat alla tidigare skapade API-nycklar och lagt till begr\u00e4nsningar f\u00f6r anv\u00e4ndning av nycklar p\u00e5 WordPress-webbplatser f\u00f6r att \u00e4ndra OptinMonster-kampanjer. <\/p>\n

Bland de data som returnerades vid anrop till det aktuella REST-API:et fanns en \u00e5tkomstnyckel som m\u00f6jliggjorde att skicka f\u00f6rfr\u00e5gningar till alla REST-API-handl\u00e4ggare. <\/p>\n

Med den erh\u00e5llna nyckeln kunde angriparen g\u00f6ra \u00e4ndringar i valfria popup-block som visades med hj\u00e4lp av OptinMonster, inklusive att k\u00f6ra sin egen JavaScript-kod.
