Detect custom domains by comparing the request host to the app host and apply
the tightened CSP there too, not just on the public path. Run the middleware
before express.static so static-served root documents get the header, and keep
helmet after static so its default-src does not block custom domain API calls.
Layer a stricter Content-Security-Policy on the /status/public document so
custom CSS cannot load external images, fonts, or stylesheets. Browsers
enforce the intersection of all CSP headers, so this only narrows the public
status page and never loosens the global policy, while keeping the app's
Google Fonts. Browser-enforced backstop behind the validator.
Replace the regex/escape-normalizer with @csstools/css-tokenizer (already
present transitively). Tokenizing resolves comments, hex escapes, and line
continuations into the real value before scanning, so obfuscated forms (a
scheme split by a line continuation or hex escape) cannot slip past. Scan
url-tokens and string-tokens to cover url(), quoted @import, and string-form
image functions. Add regression tests for the bypasses.
Reject status page custom CSS containing @import or a url() / image-set()
/ image() / cross-fade() whose target is http(s) or protocol-relative,
while allowing data: and relative URLs. The check normalizes comments and
CSS escapes first so obfuscated forms cannot slip past. Enforced in the
create/update body validation.
Bound customCSS to 100000 characters on both the client schema and the
server body validation (the server is the enforcement boundary; multer's
1MB field cap was the only limit), regenerate the OpenAPI spec, and add
a validation test suite covering acceptance, clearing, the length cap,
and type rejection.
MongoDB Atlas shared/free tiers return a legacy dbStats shape that omits
`totalSize` (while still returning storageSize/indexSize). diagnosticService
passed that undefined straight through, so the Diagnostics UI crashed with
"Expected a finite number, got undefined".
Derive totalSize (storageSize + indexSize) at the DB and per-collection level
so it always satisfies the non-optional `totalSize: number` type. Confirmed it
is not a version removal (stock mongo:8 returns totalSize) nor a permissions
issue (missing even with atlasAdmin). Adds unit tests for the derivation.
When customUpCodes mark an HTTPError as up, parse the response body, apply advancedMatcher.validate, and set status to statusUp && matchResult.ok. Return parsed payload and extracted values to match the success path.
Addresses reviewer feedback by enforcing strict validation on the array. Previously, the Zod schema accepted any arbitrary number, which could allow invalid or self-defined HTTP codes (e.g., 5000) to be saved to the database.
Refs #3657
Adds a customUpCodes field to the monitor schema to allow users to specify which HTTP status codes should be treated as UP instead of DOWN. Includes core logic in HttpProvider and unit tests.
