In versions 28.2.0 through 28.3.2, when the firewalld service is reloaded it removes all iptables rules including those created by Docker. While Docker should automatically recreate these rules, versions before 28.3.3 fail to recreate the specific rules that block external access to containers. This means that after a firewalld reload, containers with ports published to localhost (like 127.0.0.1:8080) become accessible from remote machines that have network routing to the Docker bridge, even though they should only be accessible from the host itself. The vulnerability only affects explicitly published ports &#8211; unpublished ports remain protected. This issue is fixed in version 28.3.3.<\/div>\n<\/div>\n<div style=\"padding: 15px; border-radius: 5px; margin-bottom: 20px;\">\n<h4 style=\"margin-top: 0; \">References<\/h4>\n<ul style=\"margin: 0; padding-left: 20px;\">\n<li><a href=\"https:\/\/github.com\/moby\/moby\/security\/advisories\/GHSA-x4rx-4gw3-53p4\" target=\"_blank\">https:\/\/github.com\/moby\/moby\/security\/advisories\/GHSA-x4rx-4gw3-53p4<\/a><\/li>\n<li><a href=\"https:\/\/github.com\/moby\/moby\/pull\/50506\" target=\"_blank\">https:\/\/github.com\/moby\/moby\/pull\/50506<\/a><\/li>\n<li><a href=\"https:\/\/github.com\/moby\/moby\/commit\/bea959c7b793b32a893820b97c4eadc7c87fabb0\" target=\"_blank\">https:\/\/github.com\/moby\/moby\/commit\/bea959c7b793b32a893820b97c4eadc7c87fabb0<\/a><\/li>\n<\/ul>\n<\/div>\n<div style=\"text-align: center; margin-top: 30px;\">\n<a href=\"\" target=\"_blank\" style=\"display: inline-block; background-color: #4CAF50; color: white; padding: 12px 24px; text-decoration: none; border-radius: 4px; font-weight: bold; transition: background-color 0.3s;\">View Full CVE Details<\/a>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>CVE Details Basic Information Title Moby&#8217;s Firewalld reload makes published container ports accessible from remote hosts Type cve Published 2025-07-30T13:24:06.849Z Modified 2025-07-30T13:38:07.559Z Product Information Vendor&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[6,8,109,12,21,13,7,11,5],"class_list":["post-9302","post","type-post","status-publish","format-standard","hentry","category-category_cve","tag-cve","tag-cvss","tag-cvss-51","tag-exploit","tag-medium","tag-news","tag-security","tag-tapic","tag-vulnerability"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.5 -
