CVE-2026-8829

*** Pendiente de traducción *** HTML::Entities versions before 3.84 for Perl read freed heap memory in _decode_entities.<br /> <br /> The XS routine backing HTML::Entities::_decode_entities cached a pointer (repl) into the entity-value SV returned by hv_fetch on the entity2char hash. When the input SV was identical to a value SV in that hash, and that value contained its own key as an entity reference, a later call to grow_gap() reallocated the SV&amp;#39;s PV buffer and freed the backing allocation that repl still pointed into. The subsequent copy loop read repl_len bytes from the freed allocation.<br /> <br /> The read may disclose adjacent heap contents into the destination SV.
