{"identifier":"CVE-2026-110686","cve":{"id":"CVE-2026-110686","description":"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.","published":"2026-10-19T19:17:22.200000+00:00","modified":"2026-10-19T20:50:17.967000+00:00","status":"Awaiting Analysis","score":null,"severity":"UNSCORED","vector":"","cvss_version":"","affected":[],"weaknesses":["CWE-416"],"references":[{"url":"https://github.com/rurban/Cpanel-JSON-XS/commit/c3e7e3c5b0b72d82b072c6a7cfb8c34cec4c7ea2.patch","source":"9b29abf9-4ab0-4765-b253-1875cd9b441e"},{"url":"https://metacpan.org/release/RURBAN/Cpanel-JSON-XS-4.80/changes","source":"9b29abf9-4ab0-4765-b253-1875cd9b441e"}],"kev":null,"kev_checked":true,"metrics":{},"configurations":[],"source":"nvd","retrieved_at":"2026-10-28T10:23:48.934245+00:00","exploited":false,"kev_stale":false,"products":[],"priority":{"label":"Assess exposure and vendor guidance","reasons":["No higher-priority signal is available in the current stored evidence."]},"epss":{"probability":0.00171,"percentile":0.06476,"date":"2026-10-27","stale":false},"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"github.com","source_url":"https://github.com/rurban/Cpanel-JSON-XS/commit/c3e7e3c5b0b72d82b072c6a7cfb8c34cec4c7ea2.patch","investigate_url":"https://investigate.aeglixmind.com/#github.com"},{"domain":"metacpan.org","source_url":"https://metacpan.org/release/RURBAN/Cpanel-JSON-XS-4.80/changes","investigate_url":"https://investigate.aeglixmind.com/#metacpan.org"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-110686","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-110686","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-110686","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
