{"id":"AZL-109857","summary":"CVE-2026-110678 affecting package perl-Cpanel-JSON-XS 4.39-1","details":"Cpanel::JSON::XS versions before 4.80 for Perl allow memory exhaustion by buffering incremental input past max_size in incr_parse.\n\nThe parser appends each chunk to its buffer. 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.","modified":"2026-10-30T05:32:16Z","published":"2026-10-19T19:17:21Z","upstream":["CVE-2026-110678"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-110678"}],"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-109857.json"}}],"schema_version":"1.9.2"}
