| 59 | + Tighten security restrictions within <command>REFRESH MATERIALIZED |
| 60 | + VIEW CONCURRENTLY</command> (Heikki Linnakangas) |
| 61 | + </para> |

| 63 | + <para> |
| 64 | + One step of a concurrent refresh command was run under weak security |
| 65 | + restrictions. If a materialized view's owner could persuade a |
| 66 | + superuser or other high-privileged user to perform a concurrent |
| 67 | + refresh on that view, the view's owner could control code executed |
| 68 | + with the privileges of the user running <command>REFRESH</command>. |
| 69 | + Fix things so that all user-determined code is run as the view's |
| 70 | + owner, as expected. |

| 74 | + The only known exploit for this error does not work |
| 75 | + in <productname>PostgreSQL</productname> 16.0 and later, so it may |
| 76 | + be that v16 is not vulnerable in practice. |

| 81 | + Gallegos for reporting this problem. |
