{"id":"AZL-109854","summary":"CVE-2026-110672 affecting package perl-Cpanel-JSON-XS 4.39-1","details":"Cpanel::JSON::XS versions before 4.80 for Perl leak the decoded key of an object rejected for a duplicate key or a missing colon in decode_hv.\n\nA quoted key of 24 or more bytes, or one containing a non-ASCII byte or an escape sequence, is decoded into a new scalar. 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.","modified":"2026-10-23T14:17:03.254184794Z","published":"2026-10-19T19:17:20Z","upstream":["CVE-2026-110672"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-110672"}],"affected":[{"package":{"name":"perl-Cpanel-JSON-XS","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/perl-Cpanel-JSON-XS"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"4.39-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-109854.json"}}],"schema_version":"1.9.0"}
