Splunk said in an alert this week.<\/p>\n<p>&#8220;The vulnerability exists because the PostgreSQL sidecar service endpoint lacks authentication controls, allowing any network-reachable user to invoke file operations without credentials.&#8221;<\/p>\n<p>The issue has been addressed in the following versions &#8211;<\/p>\n<ul>\n<li>Splunk Enterprise 10.0.0 to 10.0.6 &#8211; Fixed in 10.0.7<\/li>\n<li>Splunk Enterprise 10.2.0 to 10.2.3 &#8211; Fixed in 10.2.4<\/li>\n<li>Splunk Enterprise 10.4 &#8211; Not affected<\/li>\n<\/ul>\n<p>Splunk, which is part of Cisco, said Splunk Cloud is not impacted by the vulnerability as Postgres sidecars are not used in the product.<\/p>\n<h3>What the Flaw is All About<\/h3>\n<p>On Friday, watchTowr Labs released additional technical details of CVE-2026-20253, stating it could be exploited to achieve pre-authenticated remote code execution on susceptible systems through the &#8220;\/v1\/postgres\/recovery\/backup&#8221; and &#8220;\/v1\/postgres\/recovery\/restore&#8221; endpoints.<\/p>\n<p>The attack chain works as follows &#8211;<\/p>\n<ul>\n<li>Connect to an attacker-controlled database and dump its contents into an arbitrary file using the \/backup endpoint<\/li>\n<li>Load the dump of the attacker-controlled database into the local PostgreSQL instance using the \/restore endpoint by including a &#8220;passfile&#8221; argument that specifies the path to a &#8220;.pgpass&#8221; file (&#8220;\/opt\/splunk\/var\/packages\/data\/postgres\/.pgpass&#8221;) containing the password for the &#8220;postgres_admin&#8221; user<\/li>\n<li>SQL queries defined in the database dump will get executed by Splunk&#8217;s PostgreSQL instance<\/li>\n<\/ul>\n<p>An attacker could weaponize this weakness to&#8230;<\/p>\n<p><a href=\"https:\/\/thehackernews.com\/2026\/06\/critical-splunk-enterprise-flaw-lets.html\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Critical Splunk Enterprise Flaw Lets Attackers Run Code Without Authentication https:\/\/thehackernews.com\/2026\/06\/critical-splunk-enterprise-flaw-lets.html Publish Date: 2026-06-13 09:23:00&#8230;<\/p>\n","protected":false},"author":1,"featured_media":272151,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/blogger.googleusercontent.com\/img\/b\/R29vZ2xl\/AVvXsEi7NRzSRKbGdsTj1TIWcks4nX5u6n1U2vl5hxJ8KKFZ-JCAKlMQPXQNHA1i0otd63wcKJoZbeEc3oVa9o4uYNTRkRyZaJsJVGV7JUmlqjY5mQkrOXFQJXmUT1kOIZPU6CRdlwx6X7lyi7Iffz7gUIC-nYc2N1dzmiuo2hyphenhyphenPURZ3nKdQcsbLACKidjOeTbRh\/s1600\/splunk.jpg","fifu_image_alt":"","footnotes":""},"categories":[15],"tags":[27],"class_list":["post-272148","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cybersecurity","tag-vulnerability"],"_links":{"self":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/272148"}],"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=272148"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/272148\/revisions"}],"predecessor-version":[{"id":272152,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/272148\/revisions\/272152"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/272151"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=272148"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=272148"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=272148"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
