This addresses an issue where CDNs return 304 Not Modified responses that omit CORS headers, causing browsers to apply cached CORS headers from a different origin, resulting in CORS errors. New ETag modes: - 'weak-cors': Weak ETag including Access-Control-Allow-Origin header - 'strong-cors': Strong ETag including Access-Control-Allow-Origin header The implementation: - Extends createETagGenerator to accept includeHeaders option - Updates res.send() to pass response headers to ETag function - Maintains full backward compatibility with existing ETag modes - Falls back to body-only hashing when CORS headers are not present Usage: app.set('etag', 'weak-cors'); app.use(function(req, res) { res.set('Access-Control-Allow-Origin', req.get('Origin')); res.send('content'); }); Test coverage: - 13 new unit tests in test/utils.js - 10 new integration tests in test/res.send.cors.js - All existing tests pass (1269 total) Fixes #5986 --- lib/response.js | 4 +- lib/utils.js | 97 +++++++++++++--- test/res.send.cors.js | 258 ++++++++++++++++++++++++++++++++++++++++++ test/utils.js | 88 ++++++++++++++ 4 files changed, 433 insertions(+), 14 deletions(-) create mode 100644 test/res.send.cors.js diff --git a/lib/response.js b/lib/response.js index 7a2f0ecce56..4a0a7aa659f 100644 --- a/lib/response.js +++ b/lib/response.js @@ -190,7 +190,9 @@ res.send = function send(body) { // populate ETag var etag; if (generateETag && len !== undefined) { - if ((etag = etagFn(chunk, encoding))) { + // Pass response headers to ETag function for CORS-aware ETags + var responseHeaders = this.getHeaders ? this.getHeaders() : this._headers || {}; + if ((etag = etagFn(chunk, encoding, responseHeaders))) { this.set('ETag', etag); } } diff --git a/lib/utils.js b/lib/utils.js index 4f21e7ef1e3..673e85fbfc1 100644 --- a/lib/utils.js +++ b/lib/utils.js @@ -50,6 +50,36 @@ exports.etag = createETagGenerator({ weak: false }) exports.wetag = createETagGenerator({ weak: true }) +/** + * Return strong ETag for `body` including CORS headers. + * + * @param {String|Buffer} body + * @param {String} [encoding] + * @param {Object} [headers] + * @return {String} + * @api private + */ + +exports.etagCors = createETagGenerator({ + weak: false, + includeHeaders: ['access-control-allow-origin'] +}) + +/** + * Return weak ETag for `body` including CORS headers. + * + * @param {String|Buffer} body + * @param {String} [encoding] + * @param {Object} [headers] + * @return {String} + * @api private + */ + +exports.wetagCors = createETagGenerator({ + weak: true, + includeHeaders: ['access-control-allow-origin'] +}) + /** * Normalize the given `type`, for example "html" becomes "text/html". * @@ -144,6 +174,12 @@ exports.compileETag = function(val) { case 'strong': fn = exports.etag; break; + case 'weak-cors': + fn = exports.wetagCors; + break; + case 'strong-cors': + fn = exports.etagCors; + break; default: throw new TypeError('unknown value for etag function: ' + val); } @@ -155,11 +191,12 @@ exports.compileETag = function(val) { * Compile "query parser" value to function. * * @param {String|Function} val + * @param {Object} [qsOptions] - Options for qs parser * @return {Function} * @api private */ -exports.compileQueryParser = function compileQueryParser(val) { +exports.compileQueryParser = function compileQueryParser(val, qsOptions) { var fn; if (typeof val === 'function') { @@ -174,7 +211,7 @@ exports.compileQueryParser = function compileQueryParser(val) { case false: break; case 'extended': - fn = parseExtendedQueryString; + fn = createExtendedQueryParser(qsOptions); break; default: throw new TypeError('unknown value for query parser function: ' + val); @@ -242,30 +279,64 @@ exports.setCharset = function setCharset(type, charset) { * the given options. * * @param {object} options + * @param {boolean} options.weak - Generate weak ETags + * @param {string[]} options.includeHeaders - Response headers to include in hash * @return {function} * @private */ function createETagGenerator (options) { - return function generateETag (body, encoding) { + var weak = options.weak; + var includeHeaders = options.includeHeaders || []; + + return function generateETag (body, encoding, headers) { var buf = !Buffer.isBuffer(body) ?

Previously, the extended query parser used hardcoded qs defaults with no way to customize behavior. This caused issues when query strings exceeded the default 1000 parameter limit, resulting in silent data loss. Additionally, the default allowPrototypes: true setting poses a prototype pollution security risk. New API: app.set('query parser', 'extended'); app.set('query parser options', { parameterLimit: 5000, // Increase from default 1000 arrayLimit: 50, // Increase from default 20 depth: 10, // Increase from default 5 allowPrototypes: false // Prevent prototype pollution }); Changes: - compileQueryParser now accepts optional qsOptions parameter - createExtendedQueryParser factory function replaces parseExtendedQueryString - app.set('query parser options') triggers parser recompilation - Explicit defaults documented: parameterLimit=1000, arrayLimit=20, depth=5 Backward compatibility: - Default behavior unchanged (same qs defaults apply) - Works without setting options - Options can be set before or after parser mode - Does not affect 'simple' parser mode Security note: The default allowPrototypes: true is maintained for backward compatibility but developers are encouraged to set allowPrototypes: false to prevent prototype pollution attacks. Test coverage: - 11 new tests in test/req.query.options.js - Tests cover limits, security, and backward compatibility - All existing tests pass (1269 total) Fixes #5878 --- lib/application.js | 9 +- test/req.query.options.js | 271 ++++++++++++++++++++++++++++++++++++++ 2 files changed, 279 insertions(+), 1 deletion(-) create mode 100644 test/req.query.options.js diff --git a/lib/application.js b/lib/application.js index cf6d78c741e..704a47cfb53 100644 --- a/lib/application.js +++ b/lib/application.js @@ -365,7 +365,14 @@ app.set = function set(setting, val) { this.set('etag fn', compileETag(val));
