From c0632aefa8f5e9f13fd2547424fb37299530e5d3 Mon Sep 17 00:00:00 2001 From: Bastien Chanot Date: Sun, 5 Jul 2026 19:59:45 +0200 Subject: [PATCH] fix(security): pin script-src to the inline script's sha256 hash (SEC-7) unsafe-inline dropped for scripts (index has zero style/script attributes; the single inline script is hash-pinned). style-src keeps unsafe-inline (CV carries 2 style attributes + single-file convention). Verified in hardened container: served-script hash == policy hash, JS executes. --- nginx-security-headers.conf | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/nginx-security-headers.conf b/nginx-security-headers.conf index 73c1c53..182a335 100644 --- a/nginx-security-headers.conf +++ b/nginx-security-headers.conf @@ -8,5 +8,8 @@ add_header X-Content-Type-Options "nosniff" always; add_header X-Frame-Options "SAMEORIGIN" always; add_header Referrer-Policy "strict-origin-when-cross-origin" always; add_header Permissions-Policy "geolocation=(), microphone=(), camera=(), payment=()" always; -# CSP: inline CSS + JS are allowed (project convention), fonts from Google. -add_header Content-Security-Policy "default-src 'self'; style-src 'self' 'unsafe-inline' https://fonts.googleapis.com; font-src 'self' https://fonts.gstatic.com; script-src 'self' 'unsafe-inline'; img-src 'self' data:; base-uri 'self'; form-action 'self'; frame-ancestors 'self'" always; +# CSP: inline CSS allowed (style attributes in the CV + single-file convention); +# the inline script is HASH-pinned (no script unsafe-inline).
