CVE-2026-124540

*** Pendiente de traducción *** JSON::XS versions before 4.05 for Perl allow stack exhaustion via nested tagged values under allow_tags in decode_tag.<br /> <br /> With allow_tags, "(" starts a tagged value. Its tag and value are decoded recursively, and each can start another tagged value. Unlike arrays and objects, this nesting is not counted against max_depth.<br /> <br /> A run of "(" bytes exhausts the C stack and triggers an uncatchable segmentation fault regardless of max_depth.
