Overview
Affected versions of this package are vulnerable to Time-of-check Time-of-use (TOCTOU) Race Condition in the readObject function of the Maven Plugin component. An attacker can manipulate the state between the time a check is performed and the time it is used by exploiting a race condition, potentially leading to unauthorized access or modification of data. This is only exploitable if the attacker has local access and can precisely time their actions to interfere with the process.
