{"id":"ALPINE-CVE-2022-0217","details":"It was discovered that an internal Prosody library to load XML based on libexpat does not properly restrict the XML features allowed in parsed XML data. Given suitable attacker input, this results in expansion of recursive entity references from DTDs (CWE-776). In addition, depending on the libexpat version used, it may also allow injections using XML External Entity References (CWE-611).","modified":"2026-11-03T07:30:04.685382636Z","published":"2022-08-26T18:15:08.833Z","upstream":["CVE-2022-0217"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2022-0217"}],"affected":[{"package":{"name":"prosody","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/prosody?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.11.12-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-0217.json"}},{"package":{"name":"prosody","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/prosody?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.11.12-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-0217.json"}},{"package":{"name":"prosody","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/prosody?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.11.12-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-0217.json"}},{"package":{"name":"prosody","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/prosody?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.11.12-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-0217.json"}},{"package":{"name":"prosody","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/prosody?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.11.12-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-0217.json"}},{"package":{"name":"prosody","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/prosody?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.11.12-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-0217.json"}},{"package":{"name":"prosody","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/prosody?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.11.12-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-0217.json"}},{"package":{"name":"prosody","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/prosody?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.11.12-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-0217.json"}},{"package":{"name":"prosody","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/prosody?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.11.12-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-0217.json"}},{"package":{"name":"prosody","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/prosody?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.11.12-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2022-0217.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
