Nothing frees that scalar when the object is rejected for a missing ':' after the key or, from 4.09, for a duplicate key. Duplicate keys are an error unless allow_dupkeys, dupkeys_as_arrayref or relaxed is set.\n\nA process that keeps running after a failed decode retains one key per rejected document, with its size chosen by the sender. Repeated requests exhaust process memory.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-401"],"vendors":[],"products":[],"references":[{"url":"https://github.com/rurban/Cpanel-JSON-XS/commit/532b53cf8d2ca5ab6bc24048325566d1f7132425.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/532b53cf8d2ca5ab6bc24048325566d1f7132425.patch","tags":[]}],"hasPoc":true,"ai":null}
