## Technical details

A vulnerability exists in the ts_lua plugin of Apache Traffic Server due to improper management of initialization, transform context, and per-instance state. Classified under CWE-400 (Uncontrolled Resource Consumption), the flaw allows a remote attacker to trigger state inconsistencies or resource exhaustion via network requests. The root cause stems from how the plugin handles Lua script execution environments and data transformation contexts. Successful exploitation can lead to high availability impact and low confidentiality/integrity impacts. Patches are available in versions 9.2.15 and 10.1.4.
