CyberRota Analysis
AI-GeneratedThe stream-json library prior to version 3.5.0 is vulnerable to a denial of service attack due to inefficient path filtering that results in quadratic processing time for deeply nested JSON documents. Applications that process untrusted JSON data through specific filters may experience event loop blocking, leading to service disruptions. Developers and organizations using this library should prioritize upgrading to version 3.5.0 to mitigate this risk.

Original NVD Description
stream-json is a micro-library of stream components for processing JSON and JSONC with a minimal memory footprint. Prior to 3.5.0, the path filters pick, ignore, filter, and replace in src/core/filters/filter-base.js recompute the full path string from the nesting stack for every checkable token. Because the stack length equals the current nesting depth and a checkable token is emitted at every level, a depth D document costs O(D²) rather than O(D) to process. The issue is triggered by nesting depth rather than byte volume, including the documented pick({filter: 'data'}) traversal-until-match path, so an application that sends untrusted JSON through a string or RegExp filter can block the Node.js event loop and cause denial of service with a small deeply nested document. The streamArray, streamObject, and streamValues streamers are not affected because they use the constant-time asm.depth getter. This issue is fixed in version 3.5.0.
