{"id":"AZL-104916","summary":"CVE-2026-91766 affecting package php 8.3.33-1","details":"When the http:// stream wrapper follows a redirect it forwards the user-supplied Authorization, Cookie and Proxy-Authorization headers unchanged, even when the redirect target is a different host, a different port, or a downgrade from HTTPS to HTTP. A server that can steer a redirect therefore receives credentials that were only meant for the original origin. This is the same class of issue that libcurl fixed in 7.58.0 ( CVE-2018-1000007 https://github.com/advisories/GHSA-g7x2-hrfp-pv5f ).","modified":"2026-09-26T14:16:17.619182385Z","published":"2026-09-25T21:17:24Z","upstream":["CVE-2026-91766"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-91766"}],"affected":[{"package":{"name":"php","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/php"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"8.3.33-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-104916.json"}}],"schema_version":"1.9.0"}
