It is likely that a CDN or similar static file server would also mitigate the issue.", "category":"description", "title":"Vulnerability Description" } ], "product_status":{ "fixed":[ "openEuler-20.03-LTS-SP4:rubygem-rack-2.2.3.1-7.oe2003sp4.noarch", "openEuler-20.03-LTS-SP4:rubygem-rack-help-2.2.3.1-7.oe2003sp4.noarch", "openEuler-22.03-LTS-SP3:rubygem-rack-2.2.3.1-8.oe2203sp3.noarch", "openEuler-22.03-LTS-SP3:rubygem-rack-help-2.2.3.1-8.oe2203sp3.noarch", "openEuler-22.03-LTS-SP4:rubygem-rack-2.2.3.1-8.oe2203sp4.noarch", "openEuler-22.03-LTS-SP4:rubygem-rack-help-2.2.3.1-8.oe2203sp4.noarch", "openEuler-24.03-LTS:rubygem-rack-2.2.4-11.oe2403.noarch", "openEuler-24.03-LTS:rubygem-rack-help-2.2.4-11.oe2403.noarch", "openEuler-24.03-LTS-SP1:rubygem-rack-2.2.4-11.oe2403sp1.noarch", "openEuler-24.03-LTS-SP1:rubygem-rack-help-2.2.4-11.oe2403sp1.noarch", "openEuler-20.03-LTS-SP4:rubygem-rack-2.2.3.1-7.oe2003sp4.src", "openEuler-22.03-LTS-SP3:rubygem-rack-2.2.3.1-8.oe2203sp3.src", "openEuler-22.03-LTS-SP4:rubygem-rack-2.2.3.1-8.oe2203sp4.src", "openEuler-24.03-LTS:rubygem-rack-2.2.4-11.oe2403.src", "openEuler-24.03-LTS-SP1:rubygem-rack-2.2.4-11.oe2403sp1.src" ] }, "remediations":[ { "product_ids":[ "openEuler-20.03-LTS-SP4:rubygem-rack-2.2.3.1-7.oe2003sp4.noarch", "openEuler-20.03-LTS-SP4:rubygem-rack-help-2.2.3.1-7.oe2003sp4.noarch", "openEuler-22.03-LTS-SP3:rubygem-rack-2.2.3.1-8.oe2203sp3.noarch", "openEuler-22.03-LTS-SP3:rubygem-rack-help-2.2.3.1-8.oe2203sp3.noarch", "openEuler-22.03-LTS-SP4:rubygem-rack-2.2.3.1-8.oe2203sp4.noarch", "openEuler-22.03-LTS-SP4:rubygem-rack-help-2.2.3.1-8.oe2203sp4.noarch", "openEuler-24.03-LTS:rubygem-rack-2.2.4-11.oe2403.noarch", "openEuler-24.03-LTS:rubygem-rack-help-2.2.4-11.oe2403.noarch", "openEuler-24.03-LTS-SP1:rubygem-rack-2.2.4-11.oe2403sp1.noarch", "openEuler-24.03-LTS-SP1:rubygem-rack-help-2.2.4-11.oe2403sp1.noarch", "openEuler-20.03-LTS-SP4:rubygem-rack-2.2.3.1-7.oe2003sp4.src", "openEuler-22.03-LTS-SP3:rubygem-rack-2.2.3.1-8.oe2203sp3.src", "openEuler-22.03-LTS-SP4:rubygem-rack-2.2.3.1-8.oe2203sp4.src", "openEuler-24.03-LTS:rubygem-rack-2.2.4-11.oe2403.src", "openEuler-24.03-LTS-SP1:rubygem-rack-2.2.4-11.oe2403sp1.src" ], "details":"rubygem-rack security update", "category":"vendor_fix", "url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2025-1299" } ], "scores":[ { "cvss_v3":{ "baseSeverity":"HIGH", "baseScore":7.5, "vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N", "version":"3.1" }, "products":[ "openEuler-20.03-LTS-SP4:rubygem-rack-2.2.3.1-7.oe2003sp4.noarch", "openEuler-20.03-LTS-SP4:rubygem-rack-help-2.2.3.1-7.oe2003sp4.noarch", "openEuler-22.03-LTS-SP3:rubygem-rack-2.2.3.1-8.oe2203sp3.noarch", "openEuler-22.03-LTS-SP3:rubygem-rack-help-2.2.3.1-8.oe2203sp3.noarch", "openEuler-22.03-LTS-SP4:rubygem-rack-2.2.3.1-8.oe2203sp4.noarch", "openEuler-22.03-LTS-SP4:rubygem-rack-help-2.2.3.1-8.oe2203sp4.noarch", "openEuler-24.03-LTS:rubygem-rack-2.2.4-11.oe2403.noarch", "openEuler-24.03-LTS:rubygem-rack-help-2.2.4-11.oe2403.noarch", "openEuler-24.03-LTS-SP1:rubygem-rack-2.2.4-11.oe2403sp1.noarch", "openEuler-24.03-LTS-SP1:rubygem-rack-help-2.2.4-11.oe2403sp1.noarch", "openEuler-20.03-LTS-SP4:rubygem-rack-2.2.3.1-7.oe2003sp4.src", "openEuler-22.03-LTS-SP3:rubygem-rack-2.2.3.1-8.oe2203sp3.src", "openEuler-22.03-LTS-SP4:rubygem-rack-2.2.3.1-8.oe2203sp4.src", "openEuler-24.03-LTS:rubygem-rack-2.2.4-11.oe2403.src", "openEuler-24.03-LTS-SP1:rubygem-rack-2.2.4-11.oe2403sp1.src" ] } ], "threats":[ { "details":"High", "category":"impact" } ], "title":"CVE-2025-27610" } ] }
