{"id":"ALPINE-CVE-2021-28544","details":"Apache Subversion SVN authz protected copyfrom paths regression Subversion servers reveal 'copyfrom' paths that should be hidden according to configured path-based authorization (authz) rules. When a node has been copied from a protected location, users with access to the copy can see the 'copyfrom' path of the original. This also reveals the fact that the node was copied. Only the 'copyfrom' path is revealed; not its contents. Both httpd and svnserve servers are vulnerable.","modified":"2026-08-27T22:18:01.564444595Z","published":"2022-04-12T18:15:08.250Z","upstream":["CVE-2021-28544"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2021-28544"}],"affected":[{"package":{"name":"subversion","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/subversion?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.10.0"},{"fixed":"1.14.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-28544.json"}},{"package":{"name":"subversion","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/subversion?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.10.0"},{"fixed":"1.14.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-28544.json"}},{"package":{"name":"subversion","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/subversion?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.10.0"},{"fixed":"1.14.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-28544.json"}},{"package":{"name":"subversion","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/subversion?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.10.0"},{"fixed":"1.14.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-28544.json"}},{"package":{"name":"subversion","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/subversion?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.10.0"},{"fixed":"1.14.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-28544.json"}},{"package":{"name":"subversion","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/subversion?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.10.0"},{"fixed":"1.14.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-28544.json"}},{"package":{"name":"subversion","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/subversion?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.10.0"},{"fixed":"1.14.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-28544.json"}},{"package":{"name":"subversion","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/subversion?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.10.0"},{"fixed":"1.14.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-28544.json"}},{"package":{"name":"subversion","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/subversion?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.10.0"},{"fixed":"1.14.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-28544.json"}},{"package":{"name":"subversion","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/subversion?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.10.0"},{"fixed":"1.14.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-28544.json"}},{"package":{"name":"subversion","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/subversion?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.10.0"},{"fixed":"1.14.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-28544.json"}},{"package":{"name":"subversion","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/subversion?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.10.0"},{"fixed":"1.14.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2021-28544.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}
