Patches for the were released on May 25, 2026.<\/p>\n<p>The addition of CVE-2026-45247 to the KEV catalog comes days after Sansec said the PHP object injection vulnerability could be exploited by means of any storefront request carrying a crafted CacheWarmer cookie, which then deserializes part of the cookie value with PHP&#8217;s native unserialize() function without requiring any authentication or admin privileges.<\/p>\n<p>&#8220;Because that value comes straight from the client, an attacker controls the objects PHP reconstructs,&#8221; the Dutch security company said. &#8220;This is PHP object injection (CWE-502). Combined with a gadget chain from classes that Magento and its dependencies already ship, object injection escalates to remote code execution.&#8221;<\/p>\n<p>Sansec said it identified about 6,000 stores running Mirasvit extensions, although the exact number is likely to be higher given that content delivery networks (CDNs) like Cloudflare mask installs.<\/p>\n<p>Thales-owned Imperva has since disclosed it has observed active attack activity attempting to exploit CVE-2026-45247 through serialized PHP object payloads delivered via malicious HTTP&#8230;<\/p>\n<p><a href=\"https:\/\/thehackernews.com\/2026\/06\/cisa-adds-exploited-magento-rce-flaw.html\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>CISA Adds Exploited Magento RCE Flaw CVE-2026-45247 to KEV Catalog https:\/\/thehackernews.com\/2026\/06\/cisa-adds-exploited-magento-rce-flaw.html Publish Date: 2026-06-04 03:19:00&#8230;<\/p>\n","protected":false},"author":1,"featured_media":263715,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/blogger.googleusercontent.com\/img\/b\/R29vZ2xl\/AVvXsEi8P5o_wfJsxsTaxY4OONIm2y5N5x9heoFeLchfLU13YA36tGQGJtu00tOCQSKhCTBFobAAWfhXLtNGMu8ZCG7ozeLVggi1tnQVRK_1mJHd6eq1YSb5AlRZq5eDp3rGDL2Uli_b3aBPMBsLfMJ5QEm_XW1MF43_dcCf64rSbVrhsUakhaOAn5-GOmuLiq0s\/s1600\/mag.jpg","fifu_image_alt":"","footnotes":""},"categories":[15],"tags":[24,31,27],"class_list":["post-263714","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\/263714"}],"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=263714"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/263714\/revisions"}],"predecessor-version":[{"id":263716,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/263714\/revisions\/263716"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/263715"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=263714"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=263714"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=263714"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
