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.\n\nA peer that can influence read boundaries can change how many messages a stream consumer decodes and what values they carry.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-436"],"vendors":[],"products":[],"references":[{"url":"https://github.com/rurban/Cpanel-JSON-XS/commit/f632d6690d82c14cd2d76d648805325201c52b83.patch","tags":[]},{"url":"https://metacpan.org/release/RURBAN/Cpanel-JSON-XS-4.80/changes","tags":[]}],"exploitRefs":[{"url":"https://github.com/rurban/Cpanel-JSON-XS/commit/f632d6690d82c14cd2d76d648805325201c52b83.patch","tags":[]}],"hasPoc":true,"ai":null}
