In scalar or list context, it compares max_size with how far it has progressed, not with the buffer length. A chunk that starts with a NUL byte stops the parser before it progresses, and a call in void context skips the check, so the buffer grows without limit.\n\nA peer streaming data to an incr_parse consumer can exhaust process memory regardless of max_size.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-770"],"vendors":[],"products":[],"references":[{"url":"https://github.com/rurban/Cpanel-JSON-XS/commit/d516f296b1714e06b0fb9eaae72f4558ae3d83d6.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/d516f296b1714e06b0fb9eaae72f4558ae3d83d6.patch","tags":[]}],"hasPoc":true,"ai":null}
