|---|
| CCC.RDMS.TH09 | Session State Leaks Between Pooled Connections | A managed connection pool may reuse a server session for successive clients without resetting session-level state such as temporary tables, prepared statements, or an assumed role. State set by one client can then be read or acted on by another, impacting the confidentiality and integrity of data and obscuring which client performed an action. |
