Description : Cpanel::JSON::XS versions from 4. 42 before 4. 80 for Perl let input chunking change the decoded value of top-level numbers in incr_parse.
allow_nonref is enabled by default and incr_parse inherits it. A top-level number, true, false or null has no closing delimiter, so the incremental parser decodes whatever has arrived. The bytes 12 decode as one value when read together, but as 1 and then 2 when split across two reads.
A peer that can influence read boundaries can change how many messages a stream consumer decodes and what values they carry.
Severity: 0.0
- NA
