🚀 Thanks for opening this pull request! We appreciate your effort in improving the project. Please let us know once your pull request is ready for review. Tip
Note Please respond to review comments from AI agents just like you would to comments from a human reviewer. Let the reviewer resolve their own comments, unless they have reviewed and accepted your commit, or agreed with your explanation for why the feedback was incorrect. Caution Pull requests must be written using an AI agent with human supervision. Pull requests written entirely by a human will likely be rejected, because of lower code quality, higher review effort and the higher risk of introducing bugs. Please note that AI review comments on this pull request alone do not satisfy this requirement. Our CI and AI review are safeguards, not development tools. If many issues are flagged, rethink your development approach. Invest more effort in planning and design rather than using review cycles to fix low-quality code. |

🔴 Security Issues & Implementation Gaps1. Canonical Header Overwrite — Behaviour Contradicts Documentation (Critical Bug)The documented behaviour states: "If the canonical header is not present in a request, Parse Server uses the first matching alias." However, // src/middlewares.js
Object.entries(req.headers).forEach(([header, value]) => {
const targetHeader = indexHeaderByAlias[header.toLowerCase()];
if (targetHeader) {
req.headers[targetHeader] = value; // ← always overwrites, no guard
}
});If a client sends both if (targetHeader && !req.headers[targetHeader]) {
req.headers[targetHeader] = value;

File: spec/CloudCode.spec.js:4473-4487
Timestamp: 2026-03-09T19:00:02.915Z
Learning: In parse-community/parse-server, the `responseHeaders` object exposed to `afterFind` file hooks (Parse.Cloud.afterFind(Parse.File, ...)) is intentionally fully mutable by the server administrator. Admins can add, modify, or delete headers — including default security headers like `X-Content-Type-Options: nosniff` — via `req.responseHeaders`. Removing a security header is treated as an explicit, conscious decision by the person who also holds the master key. Parse Server provides secure defaults but does not enforce them as non-overridable. This is consistent with the `forceDownload` pattern that also gives Cloud Code full control over file response behavior.

File: src/Routers/FilesRouter.js:96-105
Timestamp: 2026-04-03T18:40:52.899Z
Learning: In parse-community/parse-server `src/Routers/FilesRouter.js` (PR `#10394`), the `initInfo` middleware uses `!sessionToken` (not `== null`) to gate the public-access fast path. `req.get('X-Parse-Session-Token')` returns `undefined` when the header is absent and `''` when the header is present but empty. Both values are trivially invalid session tokens; treating them identically (skipping `handleParseSession`) is intentional and correct. Using `== null` would send empty strings to `handleParseSession` for a guaranteed-failing DB lookup, which is strictly worse behavior.

Timestamp: 2026-03-18T17:53:35.669Z
Learning: In parse-community/parse-server, `src/Routers/PagesRouter.js`: the `encodeURIComponent` call in `composePageParamHeaders` is pre-existing behavior extracted from inline code in `pageResponse` and `redirectResponse`. The potential URIError on malformed Unicode (lone surrogates) when `encodePageParamHeaders` is enabled is a known pre-existing issue, not introduced by the CRLF sanitization refactor. Do not flag it as a new issue in PRs that only refactor or consolidate this call.

Learning: For Parse Server PRs, always suggest an Angular commit convention PR title that would make a meaningful changelog entry for developers. Update the PR title suggestion on every commit. The format should be: type(scope): description. Common types include feat, fix, perf, refactor, docs, test, chore. The scope should identify the subsystem (e.g., graphql, rest, push, security). The description should be action-oriented and clearly convey the change's impact to developers.

Inline comments:
In `@src/Config.js`:
- Around line 727-748: In validateHeaderAliases, after the existing type checks
in the static method validateHeaderAliases, normalize every canonicalHeader and
each alias by trimming and lowercasing, then detect and reject any collisions:
(1) an alias that normalizes to the same string as any other alias or
canonicalHeader (including its own canonicalHeader) should cause a thrown error,
and (2) any duplicate normalized alias within a single aliases array should be
rejected; use the identifiers canonicalHeader and aliases to build clear error
messages that indicate which canonical header and alias collided and throw (not
silently accept) to prevent multiple Parse headers mapping to the same effective
header.
In `@src/GraphQL/ParseGraphQLServer.js`:
- Around line 158-163: The Apollo CSRF whitelist currently includes header
aliases from parseServer.config.headerAliases via getCSRFRequestHeaders(), which
can allow CORS-safelisted names (e.g., Accept) and weaken protection; update
getCSRFRequestHeaders() to either (a) only return canonical header names (no
aliases) or (b) filter out any alias that matches a predefined set of
CORS-safelisted header names before returning (include names like Accept,
Accept-Language, Content-Language, Content-Type and other safelisted request
headers), and ensure the ApolloServer config uses that filtered list for
csrfPrevention.requestHeaders; additionally move or delay the
handleHeaderAliases middleware so it runs after Apollo's CSRF check (or remove
alias handling from the pre-CSRF path) to avoid aliasing before validation.
In `@src/middlewares.js`:
- Around line 86-116: getHeaderAliases and applyHeaderAliases assume
headerAliases is an object and will throw if undefined; in handleHeaderAliases,
ensure the config?.headerAliases value is null-safe before passing it (e.g.,
default to {} or guard and skip application). Update handleHeaderAliases to call
applyHeaderAliases(req, config?.headerAliases || {}) or guard in
applyHeaderAliases/getHeaderAliases to handle non-object inputs, referencing
functions getHeaderAliases, applyHeaderAliases and the call site in
handleHeaderAliases that uses Config.get(appId, getMountForRequest(req)).
- Around line 95-110: In applyHeaderAliases, avoid letting alias headers clobber
an existing canonical header: for each canonical name in headerAliases, first
check (case-insensitively) if req.headers already contains the canonical name
and if so do nothing; otherwise iterate the configured aliases in their defined
order and, for the first alias present in req.headers (case-insensitive), copy
that value into the canonical header slot. Use lowercased lookups for
comparisons but do not overwrite an existing canonical header; ensure alias
precedence comes from headerAliases' alias array order rather than request
header iteration order.
In `@src/ParseServer.ts`:
- Line 314: The middleware currently overwrites canonical headers with aliases;
update the implementation in handleHeaderAliases/applyHeaderAliases so that for
each header alias mapping it only sets the canonical header value when the
canonical header is missing or empty (do not overwrite when request.headers has
the canonical key present), and ensure you preserve original header casing/keys
used by Parse logic; also add a unit/integration test that sends both canonical
and alias headers and asserts the canonical header value is preserved and used
for authentication/application-id resolution.

- Around line 1741-1788: Add a regression test that verifies canonical REST
headers take precedence over aliases when both are present with conflicting
values: within the existing "rest header aliases" describe block create a test
that calls reconfigureServer({ headerAliases: { 'X-Parse-Application-Id':

a request to /schemas (or another endpoint) including both the canonical header
(e.g., 'X-Parse-Application-Id') set to an invalid value and the alias header
('X-App-Id') set to a valid value and assert the request fails (or uses the
canonical value), and similarly create a /users/me test where you sign up a
user, send both 'X-Parse-Session-Token' with an invalid token and
'X-Session-Token-Alias' with the real session token and assert the canonical
'X-Parse-Session-Token' governs authentication (e.g., request is rejected or
returns the user matching the canonical token behavior); ensure you call
reconfigureServer() in finally to reset server.
In `@src/Config.js`:
- Around line 727-802: validateHeaderAliases must enforce a canonical allowlist
and strict header-name character rules: add a canonical allowlist (e.g.,
HEADER_CANONICAL_ALLOWLIST) and, inside validateHeaderAliases, reject any
canonicalHeader not present in that allowlist (use
normalizeHeaderAliasIdentifier for lookup); additionally validate both
canonicalHeader and each alias against a safe header-name pattern (allow only
letters, digits and hyphen [A-Za-z0-9-], no leading/trailing hyphen, no empty
strings, and reject control chars/CRLF or any `:`) before existing
normalization/duplication checks (affecting the loops that build
canonicalNormToKey and globalAliasNorm and the normalizeHeaderAliasIdentifier
usage).

Do not enable privileged-key aliases through the generic allowlist.
Allowing aliases for X-Parse-Master-Key and X-Parse-Maintenance-Key creates hidden credential ingress paths that canonical-header proxy, WAF, and audit rules may miss. The master key bypasses Parse application security controls. (docs.parseplatform.org)

Validate aliases as an allowlisted, one-to-one mapping before rewriting headers.
This loop accepts arbitrary canonical destinations and permits one case-insensitive alias to populate multiple headers. That turns the feature into generic pre-auth header rewriting and makes conflicting mappings ambiguous.
Restrict destinations to supported Parse headers and reject aliases already owned by another canonical header in Config.validateHeaderAliases.

Issue
Security hardening through header masking:
According to OWASP recommendations, it is best practice to mask or obfuscate technology-specific details whenever possible. For example, headers such as X-Parse-Session-Token and X-Parse-Application-Id clearly reveal the backend technology stack and should be renamed or aliased to reduce exposure.
Session management in micro frontend architectures or multi parse-server under one domain:
In a micro frontend setup with multiple Parse Server instances under the same domain, developers may not be able to use HttpOnly cookies. As a result, they might be forced to rely on alternative methods, often less secure, such as localStorage or sessionStorage to manage session tokens across instances.
This feature allows developers to configure alias names for session headers and application IDs, helping maintain flexibility while improving security.
Approach
Alias system: redirects the value of a custom (aliased) header to the corresponding internally recognized Parse header.
Made with Composer 2 and Codex 5.3 High + manually reduced implementation complexity
