Critically, the system enforces a human-in-the-loop (HITL) approach; no patch is applied without developer approval.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/thecybernews.com\/csngoogle.svg\n\" alt=\"google\"\/><\/p>\n<p>During Anthropic internal testing, the tool already uncovered over 500 previously unknown high-severity vulnerabilities across operational open-source codebases, many of which had gone undetected for years.<\/p>\n<p>The announcement triggered a sweeping selloff across the&#8230;<\/p>\n<p><a href=\"https:\/\/cybersecuritynews.com\/claude-security-tool-stocks-impacted\/\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Cybersecurity Companies&#8217; Stocks Fall Sharply as Anthropic Releases Claude Security Tool https:\/\/cybersecuritynews.com\/claude-security-tool-stocks-impacted\/ Publish Date: 2026-02-21&#8230;<\/p>\n","protected":false},"author":1,"featured_media":216092,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/blogger.googleusercontent.com\/img\/b\/R29vZ2xl\/AVvXsEib8mHdoLqhvLXcgEVNnXje_j_KCBhG3HhdLLy4Z79cx5WaTqTQ3oJibVcyTSmnMtqN6IU4L3uF-s74t7Nxla3uRaIBVNm7XNZEWTsR-_aUnd3nUsYf2YyQIuSZ9yH-jyqpMdFjIXhbIOETdP7mZbGVkc42TVmzQMqcyWuGC1knyjAB953VJBZB-F2gf-uP\/s16000\/Claude%20Security%20Tool%20Stocks%20Impacted.webp","fifu_image_alt":"","footnotes":""},"categories":[15],"tags":[20,57,27],"class_list":["post-216091","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cybersecurity","tag-artificial-intelligence","tag-security","tag-vulnerability"],"_links":{"self":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/216091"}],"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=216091"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/216091\/revisions"}],"predecessor-version":[{"id":216093,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/216091\/revisions\/216093"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/216092"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=216091"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=216091"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=216091"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
