Advisory Weakness Curation

Denial-of-Service Extended Event Loop Blocking in qs Versions prior to 1.0.0 of `qs` are affected by a denial of service vulnerability that results from excessive recursion in parsing a deeply nested JSON string. ## Recommendation Update to version 1.0.0 or later

Denial-of-Service Extended Event Loop Blocking in qs The qs module before 1.0.0 does not have an option or default for specifying object depth and when parsing a string representing a deeply nested object will block the event loop for long periods of time. An attacker could leverage this to cause a temporary denial-of-service condition, for example, in a web application, other requests would not be processed while this blocking is occurring.
