Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Netplex Json-smart (net.minidev:json-smart) versions 2.5.0 through 2.5.1 are vulnerable. An attacker who can supply a specially crafted JSON input with a large number of opening braces can exhaust the stack, causing a denial of Service. Upgrade to version 2.5.2. If you construct the parser manually or with custom options, set the LIMIT_JSON_DEPTH option.
