Seroval: Memory exhaustion via unchecked TypedArray length in JSON deserialization

Summary deserializeTypedArray casts the source node to ArrayBuffer without checking it and never bounds the element count. Pass a plain object with a length property and it hits the array-like TypedArray constructor, allocating that many elements. The offset guard above it can't stop this:...

stream-json: JSONC parser and verifier re-scan the whole accumulated comment on every input chunk

Summary The JSONC parser stream-json/jsonc/parser.js and verifier stream-json/jsonc/verifier.js scan a comment for its terminator starting from the comment's opening / on every input chunk. When a comment doesn't finish inside the current buffer, the scanner returns the comment's start offset and...
