{"id":"BIT-php-min-2026-91766","summary":"Cross-origin credential leak in HTTP stream wrapper redirects","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 ).","aliases":["BIT-libphp-2026-91766","BIT-php-2026-91766","CVE-2026-91766"],"modified":"2026-10-01T10:11:17.593802678Z","published":"2026-10-01T09:34:19.399Z","database_specific":{"cpes":["cpe:2.3:a:php:php:*:*:*:*:*:*:*:*"],"severity":"Medium"},"references":[{"type":"WEB","url":"https://github.com/php/php-src/security/advisories/GHSA-fpwc-w8rq-cr92"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-91766"}],"affected":[{"package":{"name":"php-min","ecosystem":"Bitnami","purl":"pkg:bitnami/php-min"},"ranges":[{"type":"SEMVER","events":[{"introduced":"8.2.0"},{"fixed":"8.2.34"},{"introduced":"8.3.0"},{"fixed":"8.3.35"},{"introduced":"8.4.0"},{"fixed":"8.4.26"},{"introduced":"8.5.0"},{"fixed":"8.5.11"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/php-min/BIT-php-min-2026-91766.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}],"schema_version":"1.9.0"}
