Cisco said there are no workarounds that address the vulnerability.<\/p>\n<p>The issue has been addressed in the following versions &#8211;<\/p>\n<ul>\n<li>Cisco Secure Workload Release 3.9 and earlier (Migrate to a fixed release)<\/li>\n<li>Cisco Secure Workload Release 3.10 (Fixed in 3.10.8.3)<\/li>\n<li>Cisco Secure Workload Release 4.0 (Fixed in 4.0.3.17)<\/li>\n<\/ul>\n<p>The networking equipment major said it found the vulnerability during internal security testing and that there is no evidence of it being exploited in the wild.<\/p>\n<p>The disclosure comes a week after Cisco revealed that another maximum-severity authentication bypass flaw in Catalyst SD-WAN Controller (CVE-2026-20182, CVSS score: 10.0) has been exploited by a threat actor known as UAT-8616 to gain unauthorized access to SD-WAN systems.<\/p>\n<p><a href=\"https:\/\/thehackernews.com\/2026\/05\/cisco-patches-cvss-100-secure-workload.html\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Cisco Patches CVSS 10.0 Secure Workload REST API Flaw Enabling Data Access https:\/\/thehackernews.com\/2026\/05\/cisco-patches-cvss-100-secure-workload.html Publish Date:&#8230;<\/p>\n","protected":false},"author":1,"featured_media":252139,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/blogger.googleusercontent.com\/img\/b\/R29vZ2xl\/AVvXsEiLweJvl8B70zomibdr4U6WvYgbmZn4gKKOG9F7xDPXzgeENKK0kg2kgK1yvZDS7AJFkY9De2rG2EQzCLvN1FmjrXXDIm-CkmU88QcexbMkr60gKVKexF-d1qtGHusrr6_j5yrtMv31PSUEygioHJikBsifQ0VHW18IU7lu_oItTzQXugwHPLoO_DYNdnYx\/s1600\/cisco-workload.jpg","fifu_image_alt":"","footnotes":""},"categories":[15],"tags":[31,29,34,27],"class_list":["post-252138","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cybersecurity","tag-exploit","tag-network-security","tag-threat-actor","tag-vulnerability"],"_links":{"self":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/252138"}],"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=252138"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/252138\/revisions"}],"predecessor-version":[{"id":252140,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/252138\/revisions\/252140"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/252139"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=252138"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=252138"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=252138"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
