      "value": "Tiptap for PHP before version 2.1.1 contains an input validation vulnerability that allows authenticated attackers to cause a denial of service by submitting Tiptap JSON with the attrs.href field set to an array instead of a string, causing an unhandled TypeError in the Link::isAllowedUri() function when passed to preg_match(). Attackers can persist malformed JSON records that permanently crash the server-side HTML rendering pipeline for all subsequent viewers of that record until the database entry is manually repaired."

Los atacantes pueden persistir registros JSON malformados que bloquean permanentemente la canalización de renderizado HTML del lado del servidor para todos los espectadores posteriores de ese registro hasta que la entrada de la base de datos sea reparada manualmente."
