Subsequent analysis of these vulnerability candidates has identified that 1,726 are valid true positives. As many as 1,094 flaws are assessed to be either high- or critical-severity.<\/p>\n<p>One of the identified weaknesses is a critical flaw in WolfSSL (CVE-2026-5194, CVSS score: 9.1) that could allow an attacker to forge certificates and masquerade as a legitimate service. In all, these efforts have led to 97 findings being patched upstream and 88 advisories being issued.<\/p>\n<p>&#8220;The relative ease of finding vulnerabilities compared with the difficulty of fixing them amounts to a major challenge for cybersecurity,&#8221; Anthropic acknowledged. &#8220;Confronting this challenge successfully will make our software far safer than before.&#8221;<\/p>\n<p>The development comes as software vendors are shipping more fixes than ever before, driven by a surge in AI-assisted vulnerability discovery, with Microsoft noting that the number of new patches it expects to release on a monthly basis to &#8220;continue trending larger for some time.&#8221;<\/p>\n<p>Autonomous offensive security platform XBOW has described Mythos Preview as &#8220;a major advance&#8221; that&#8217;s &#8220;substantially better than prior models at finding vulnerability candidates&#8221; and &#8220;adept at analyzing source code with a security mindset.&#8221; Recent&#8230;<\/p>\n<p><a href=\"https:\/\/thehackernews.com\/2026\/05\/claude-mythos-ai-finds-10000-high.html\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Claude Mythos AI Finds 10,000 High-Severity Flaws in Widely Used Software https:\/\/thehackernews.com\/2026\/05\/claude-mythos-ai-finds-10000-high.html Publish Date: 2026-05-23&#8230;<\/p>\n","protected":false},"author":1,"featured_media":253264,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/blogger.googleusercontent.com\/img\/b\/R29vZ2xl\/AVvXsEjOPcHXcMRS-BJNvy9aeoCz5H2Mmdh6mO6Kl3kM-l216B-3Wc0Iy5wayPkxJ79KtkHx2CGBwDVPMMeuB9E3jQlPXsa-vKqALoAuTwmEwsbH5sK0xs9xb_XWgk4uaGazYAcswrLxdX0QL74k7e85WXfL03rHFQStuxqpJFsJBcAQLOvNXSuX2YNBAScQStvj\/s1600\/claude-mythos-flaws.jpg","fifu_image_alt":"","footnotes":""},"categories":[15],"tags":[20,90,89,57,27],"class_list":["post-253263","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cybersecurity","tag-artificial-intelligence","tag-cve","tag-flaw","tag-security","tag-vulnerability"],"_links":{"self":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/253263"}],"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=253263"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/253263\/revisions"}],"predecessor-version":[{"id":253265,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/253263\/revisions\/253265"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/253264"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=253263"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=253263"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=253263"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
