stream-json/jsonc parser JSONC DoS

The vulnerability in the stream-json/jsonc/parser.js and stream-json/jsonc/verifier.js libraries for processing JSON and JSONC streams is related to inefficient algorithmic complexity. Exploiting this vulnerability can allow attackers to cause service failures...

JSON processing library Prototype Pollution

The vulnerability of the JSON processing library and stream-json is related to inadequate control over changes to prototype attributes. Exploiting this vulnerability could allow an attacker to execute a “prototype pollution” attack...

GHSA-HQR4-QQ8F-HG3X 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...

CVE-2026-104183

A flaw was found in stream-json. When parsing JSON data, the Assembler component directly assigns properties, allowing an input key named 'proto' to replace a parsed object's internal prototype rather than creating a standard property. An attacker who supplies crafted input can exploit this...
