(Fixed in June 2025)<\/li>\n<li><strong>CVE-2025-68461<\/strong> (CVSS score: 7.2) &#8211; A cross-site scripting vulnerability via the animate tag in an SVG document. (Fixed in December 2025)<\/li>\n<\/ul>\n<p>Dubai-based cybersecurity company FearsOff, whose founder and CEO, Kirill Firsov, was credited with discovering and reporting CVE-2025-49113, said attackers have already &#8220;diffed and weaponized the vulnerability&#8221; within 48 hours of public disclosure of the flaw. An exploit for the vulnerability was subsequently made available for sale on June 4, 2025.<\/p>\n<p>Firsov also noted that the shortcoming can be triggered reliably on default installations, and that it had been hidden in the codebase for over 10 years.<\/p>\n<p>There are no details on who is behind the exploitation of the two Roundcube flaws. But multiple vulnerabilities in the email software have been weaponized by nation-state threat actors like APT28 and Winter Vivern.<\/p>\n<p>Federal Civilian Executive Branch (FCEB) agencies are to remediate identified vulnerabilities by March 13, 2026, to secure their networks against the active threat.<\/p>\n<p><a href=\"https:\/\/thehackernews.com\/2026\/02\/cisa-adds-two-actively-exploited.html\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>CISA Adds Two Actively Exploited Roundcube Flaws to KEV Catalog https:\/\/thehackernews.com\/2026\/02\/cisa-adds-two-actively-exploited.html Publish Date: 2026-02-21 02:21:00&#8230;<\/p>\n","protected":false},"author":1,"featured_media":215920,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/blogger.googleusercontent.com\/img\/b\/R29vZ2xl\/AVvXsEhtZg49iJDSf0QXV_lj9uqgkcevxHhncfWJrejyCIdGb2hlzcVefAWXETqflE7uEUTuAGKkqfSpa9_w1FoNTZ-67YU4H-iUio2DfhF7o2qIMIbx8BewvMG8rHsq8eh7gBwjVckasb5Qj8jsGY_3wRjBaYTh-nL10wAWFI5PbCu62cfJFk9Y8ucUBDyQNkEh\/s1600\/roundcube.jpg","fifu_image_alt":"","footnotes":""},"categories":[15],"tags":[24,31,27],"class_list":["post-215919","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cybersecurity","tag-cybersecurity","tag-exploit","tag-vulnerability"],"_links":{"self":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/215919"}],"collection":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/comments?post=215919"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/215919\/revisions"}],"predecessor-version":[{"id":215921,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/215919\/revisions\/215921"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/215920"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=215919"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=215919"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=215919"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
