--------------------------------
Summary: JSON parsing allows non-whitespace trailing characters
Key: MESOS-3698
URL: https://issues.apache.org/jira/browse/MESOS-3698
Project: Mesos
Issue Type: Bug
Reporter: Greg Mann
Assignee: Greg Mann
Picojson supports a streaming mode in which a stream containing a series of
JSON values can be repeatedly parsed. For this reason, it does not return an
error when passed a string containing a valid JSON value followed by
non-whitespace trailing characters.
However, picojson contains a two-argument {{parse()}} function
(https://github.com/kazuho/picojson/blob/master/picojson.h#L938-L942) which
should probably validate its input string to ensure it doesn't contain trailing
characters. A pull request has been filed for this change at
https://github.com/kazuho/picojson/pull/70 and if it's merged, we can switch to
the two-argument function call. In the meantime, we should provide such input
validation ourselves in {{JSON::parse()}}.
