In versions 1.19.1 and below, attackers can exploit the way GitProxy handles new branch creation to bypass the approval of prior commits on the parent branch. The vulnerability impacts all users or organizations relying on GitProxy to enforce policy and prevent unapproved changes. It requires no elevated privileges beyond regular push access, and no extra user interaction. It does however, require a GitProxy administrator or designated user (canUserApproveRejectPush) to approve pushes to the child branch. This is fixed in version 1.19.2.<\/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\/finos\/git-proxy\/security\/advisories\/GHSA-39p2-8hq9-fwj6\" target=\"_blank\">https:\/\/github.com\/finos\/git-proxy\/security\/advisories\/GHSA-39p2-8hq9-fwj6<\/a><\/li>\n<li><a href=\"https:\/\/github.com\/finos\/git-proxy\/commit\/a620a2f33c39c78e01783a274580bf822af3cc3a\" target=\"_blank\">https:\/\/github.com\/finos\/git-proxy\/commit\/a620a2f33c39c78e01783a274580bf822af3cc3a<\/a><\/li>\n<li><a href=\"https:\/\/github.com\/finos\/git-proxy\/commit\/f99fe42082eab0970e4cd0acdc3421a527a7e531\" target=\"_blank\">https:\/\/github.com\/finos\/git-proxy\/commit\/f99fe42082eab0970e4cd0acdc3421a527a7e531<\/a><\/li>\n<li><a href=\"https:\/\/github.com\/finos\/git-proxy\/releases\/tag\/v1.19.2\" target=\"_blank\">https:\/\/github.com\/finos\/git-proxy\/releases\/tag\/v1.19.2<\/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 GitProxy is vulnerable to a new branch approval exploit Type cve Published 2025-07-30T20:17:20.844Z Modified 2025-07-30T20:30:27.179Z Product Information Vendor finos Product&#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":[6,8,77,12,15,13,7,11,5],"class_list":["post-9345","post","type-post","status-publish","format-standard","hentry","category-category_cve","tag-cve","tag-cvss","tag-cvss-82","tag-exploit","tag-high","tag-news","tag-security","tag-tapic","tag-vulnerability"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.5 -
