Attackers can append 0x1A and malformed content to pass JSONValue.parseStrict or isValidJsonStrict validation, creating parser differentials with downstream parsers like Jackson or Gson.","cvssScore":5.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","cwes":["CWE-147"],"vendors":[],"products":[],"references":[{"url":"https://github.com/netplex/json-smart-v2/blob/v2.6.0/json-smart/src/main/java/net/minidev/json/parser/JSONParserBase.java","tags":[]},{"url":"https://github.com/netplex/json-smart-v2/issues/302","tags":[]},{"url":"https://www.vulncheck.com/advisories/json-smart-through-2.6.0-strict-mode-validation-bypass-via-0x1a-character","tags":[]},{"url":"https://github.com/netplex/json-smart-v2/issues/302","tags":[]}],"exploitRefs":[{"url":"https://github.com/netplex/json-smart-v2/blob/v2.6.0/json-smart/src/main/java/net/minidev/json/parser/JSONParserBase.java","tags":[]},{"url":"https://github.com/netplex/json-smart-v2/issues/302","tags":[]},{"url":"https://github.com/netplex/json-smart-v2/issues/302","tags":[]}],"hasPoc":true,"ai":null}
