The researchers chained together five separate weaknesses which were exploitable with just a free Zapier account. The vulnerabilities began with flaws in users\u2019 code snippets within automations, leading to the recovery of discarded login credentials. This then exposed Zapier\u2019s internal storage system, including a publishing key. With this, an attacker could have impersonated legitimate users, modifying or creating new automations and interfacing with external services. Although passwords and keys for connected services remained secure, actions performed via Zapier would appear legitimate on those services. The researchers found practical implications of this by manipulating a key from an external company&#8217;s CTO to send emails from their Gmail. Zapier addressed these issues promptly and paid the maximum reward under their bug-bounty program. The researchers suggested that organizations, particularly those interfacing with sensitive systems, review their automation activities and reauthorize connections to ensure security.<\/p>\n<p>Key Points:<br \/>\n&#8211; Researchers discovered a chain of five vulnerabilities in Zapier that could have allowed unauthorized access to millions of user accounts and connected systems.<br \/>\n&#8211; The vulnerabilities could be exploited with only a basic Zapier account, involving flaws in code snippets and the exposure of internal storage.<br \/>\n&#8211; An attacker could impersonate users to perform activities via connected third-party services, which would appear legitimate from the connected services\u2019 perspective.<br \/>\n&#8211; The discovered risk included the potential to manipulate an executive&#8217;s account, demonstrating the immediacy of the threat.<br \/>\n&#8211; Zapier quickly addressed the vulnerabilities under a bug bounty program, but researchers cautioned similar risks may exist at other companies using similar automation platforms.<br \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Zapier fixes bug chain that researchers say risked widespread account takeover https:\/\/cyberscoop.com\/zapier-bug-chain-account-takeover-patched\/ Publish Date: 2026-05-28&#8230;<\/p>\n","protected":false},"author":1,"featured_media":224959,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/cyberscoop.com\/wp-content\/uploads\/sites\/3\/2026\/04\/Gregory-Otto_26-03-23_DTEX_March_2026_0136.jpg?w=150&h=150&crop=1","fifu_image_alt":"","footnotes":""},"categories":[15],"tags":[],"class_list":["post-224958","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cybersecurity"],"_links":{"self":[{"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/224958"}],"collection":[{"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/comments?post=224958"}],"version-history":[{"count":1,"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/224958\/revisions"}],"predecessor-version":[{"id":224960,"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/224958\/revisions\/224960"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/224959"}],"wp:attachment":[{"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=224958"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=224958"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/testing.news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=224958"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
