c3p0 can, in combination with other libraries, compose to a "sink" for deserialization gadgets
GitHub lists this reviewed advisory for com.mchange:c3p0. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.
01 / Meaning
Why it matters
Published affected context helps an owner decide what evidence to gather. This report has not examined your application.

### Impact The JDBC spec defines the interface `DataSource`, with a method called `getConnection()`, and `ConnectionPoolDataSource`, with a method called `getPooledConnection()`. These methods are potentially dangerous. One way or another they trigger calls into JDBC drivers, which themselves are complicated, flexible tools which may be, and in practice sometimes have proven to be, susceptible to abuse. Unfortunately, the JavaBean framework treats methods of this form, `getXXX()`, as JavaBean "properties", which JavaBean-related libraries often presume represent quick, safe-to-look-up, state or configuration. Attackers therefore can construct malicious `DataSource` objects — objects whose calls to `getConnection()` or `getPooledConnection()` would trigger attacks via vulnerable JDBC drivers — and bundle them in contexts that automatically look up bean properties on deserialization. If an attacker can smuggle such an object in serialized form to a location from which an application will deserialize it, an attack is triggered. It's not easy. It requires that a susceptible JDBC `DataSource` or `ConnectionPoolDataSource` be available on the application `CLASSPATH`, along with a sus
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
