From 1.16.0 until 1.16.1, escapeRegex leaves valid header-name metacharacters unescaped in sensitiveHeaders. When an application declares a sensitive header whose name contains ^ or | and follows a cross-origin or HTTPS-to-HTTP redirect, unescaped regular-expression metacharacters prevent the generated filter from matching the declared header name, and the credential header is forwarded to an attacker-controlled redirect target. This issue is fixed in version 1.16.1.","state":0,"publishedAt":"2026-10-19T18:17:00.26+00:00","modifiedAt":"2026-10-19T21:13:39.973+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":8.2,"severity":"HIGH"}],"references":["https://github.com/follow-redirects/follow-redirects/commit/080a76d0e125b37bf81717368a61d5dc37aa56c8","https://github.com/follow-redirects/follow-redirects/releases/tag/v1.16.1","https://github.com/follow-redirects/follow-redirects/security/advisories/GHSA-8r9p-f939-6h3c"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-111755","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-185","CWE-200"],"productCriteria":[],"sourceDates":{"published":"2026-10-19T18:17:00.260","lastModified":"2026-10-19T21:13:39.973"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
