{"id":"ALPINE-CVE-2026-93682","details":"When the HTTP stream wrapper follows a redirect and the response carries a Location header with an empty value, the redirect code reads one byte past the end of the heap buffer holding the location. The value of that out-of-bounds byte decides which redirect target is built, so a malicious server controls whether the client is sent to the host root or to the current directory.","modified":"2026-11-03T06:33:04.702573974Z","published":"2026-09-25T20:17:47.597Z","upstream":["CVE-2026-93682"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2026-93682"}],"affected":[{"package":{"name":"php82","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/php82?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.2.35-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-93682.json"}},{"package":{"name":"php83","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/php83?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.3.36-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-93682.json"}},{"package":{"name":"php83","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/php83?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.3.36-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-93682.json"}},{"package":{"name":"php83","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/php83?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.3.35-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-93682.json"}},{"package":{"name":"php84","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/php84?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.4.27-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-93682.json"}},{"package":{"name":"php84","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/php84?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.4.27-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-93682.json"}},{"package":{"name":"php84","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/php84?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.4.26-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-93682.json"}},{"package":{"name":"php85","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/php85?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.5.12-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-93682.json"}},{"package":{"name":"php85","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/php85?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.5.11-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-93682.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N"}]}
