{
    "lastseen": "",
    "description": "Buffer over-read in PostgreSQL function pg_restore_attribute_stats() accepts array values of unmatched length, which causes query planning to read past end of one array.  This allows a table maintainer to infer memory values past that array end.  Within major version 18, minor versions before PostgreSQL 18.4 are affected.  Versions before PostgreSQL 18 are unaffected.",
