jenkins before versions 2.44, 2.32.2 is vulnerable to an improper blacklisting of the Pipeline metadata files in the agent-to-master security subsystem. This could allow metadata files to be written to by malicious agents (SECURITY-358).
The product implements a protection mechanism that relies on a list of inputs (or properties of inputs) that are not allowed by policy or otherwise require other action to neutralize before additional processing takes place, but the list is incomplete.
