{"id":"AZL-109851","summary":"CVE-2026-110685 affecting package perl-Cpanel-JSON-XS 4.39-1","details":"Cpanel::JSON::XS versions before 4.80 for Perl leak the decoded arguments of a tagged value when its THAW method dies in decode_tag.\n\nWith allow_tags, a tagged value's class name and argument array are decoded and passed to the class's THAW method. Both are released only after THAW returns, so a THAW that dies leaves the whole decoded argument structure allocated.\n\nEach rejected document leaks data of a size the sender chooses, so a process that catches the error and keeps running exhausts its memory.","modified":"2026-10-24T05:31:11Z","published":"2026-10-19T19:17:22Z","upstream":["CVE-2026-110685"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-110685"}],"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-109851.json"}}],"schema_version":"1.9.0"}
