{"id":"AZL-109860","summary":"CVE-2026-110686 affecting package perl-Cpanel-JSON-XS 4.39-1","details":"Cpanel::JSON::XS versions before 4.80 for Perl use freed filter callbacks when a filter removes itself during decoding in decode_hv.\n\nA decode copies the parser's filter_json_object and filter_json_single_key_object callbacks without taking references to them. A filter callback that removes the last single-key filter frees the callback table while the decode in progress still uses it. The next object is dispatched through freed memory and can crash the process.","modified":"2026-10-24T05:31:11Z","published":"2026-10-19T19:17:22Z","upstream":["CVE-2026-110686"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-110686"}],"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-109860.json"}}],"schema_version":"1.9.0"}
