{"id":"CVE-2026-110685","summary":"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","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":"2026-10-20T02:44:17.096627729Z","published":"2026-10-19T18:12:17.344Z","database_specific":{"cwe_ids":["CWE-401"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110685.json","cna_assigner":"CPANSec"},"references":[{"type":"WEB","url":"https://cpan.org/modules"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/110xxx/CVE-2026-110685.json"},{"type":"PACKAGE","url":"https://github.com/rurban/Cpanel-JSON-XS"},{"type":"FIX","url":"https://github.com/rurban/Cpanel-JSON-XS/commit/9ab010221c069a7af9ef7463454ecd3b8ace9c58.patch"},{"type":"ADVISORY","url":"https://metacpan.org/release/RURBAN/Cpanel-JSON-XS-4.80/changes"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-110685"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/rurban/cpanel-json-xs","events":[{"introduced":"0"},{"fixed":"5552a527abb648d9eb4134e91412800013ddecb9"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"4.80"}],"source":"AFFECTED_FIELD"}}],"versions":["4.53","4.52","4.51","4.50","4.44","4.43","4.42","4.41","4.40","4.39","4.38","4.37","4.36","4.35","4.34","4.33","4.32","4.31","4.30","4.29","4.28","4.27","4.26","4.25","4.24","4.23","4.22","4.21","4.20","4.19","4.18","4.17","4.16","4.15","4.14","4.13","4.12","4.11","4.10","4.09","4.08","4.07","4.06","4.05","4.04","4.03","4.02","4.01","4.00","3.99_03","3.99_02","3.99_01","3.0240","3.0239","3.0238","3.0237","3.0236","3.0235","3.0234","3.0233","3.0232","3.0229","3.0227","3.0226","3.0225","3.0224","3.0223","3.0222","3.0221","3.0220","3.0219","3.0218","3.0217_06","3.0217_05","3.0217_04","3.0217_03","3.0217_02","3.0217_01","3.0217","3.0216","3.0215","3.0214","3.0213_02","3.0213_01","3.0213","3.0212","3.0211","3.0210","3.0209","3.0208","3.0207","3.0206","3.0205","3.0204","3.0202","3.0201","3.0115","3.0114","3.0113","3.0112","3.0111","3.0110","3.0109","3.0106","3.0105","3.0104","3.0103","3.0102","3.0101","2.3404","2.3403","2.3402","2.3401","2.3314","2.3313","2.3311","2.3310","2.3309","2.3308","2.3307","2.3306","2.3305","2.33_04","2.33_02","2.32","2.31","2.3","2.29","2.28","2.27"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-110685.json"}}],"schema_version":"1.9.0"}
