NVD Description

Note: Versions mentioned in the description apply only to the upstream json-smart package and not the json-smart package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

json-smart through 2.6.0 contains an input validation bypass vulnerability that allows attackers to evade strict-mode trailing-data checks by inserting a literal 0x1A character. Attackers can append 0x1A and malformed content to pass JSONValue.parseStrict or isValidJsonStrict validation, creating parser differentials with downstream parsers like Jackson or Gson.
