 Please file a private vulnerability report via GitHub, email [@ljharb](https://github.com/ljharb), or see https://tidelift.com/security if you have a potential security vulnerability to report.
 
+## Escalation
+
+If you do not receive an acknowledgement of your report within 6 business days, or if you cannot find a private security contact for the project, you may escalate to the OpenJS Foundation CNA at `security@lists.openjsf.org`.
+
+If the project acknowledges your report but does not provide any further response or engagement within 14 days, escalation is also appropriate.
