Root Cause Analysis
The vulnerability stems from the drb_remote_codeexec module's use of DRb.start_service, which creates an insecure DRb server. The GitHub PR #14300 explicitly removed this service initialization (commit 49145bf) to mitigate the risk. The CWE-502 (Deserialization of Untrusted Data) aligns with DRb's known insecure deserialization behavior. The module's removal in PR #14335 further confirms the inherent vulnerability in its DRb implementation.
