+used before a patch is released.
+
+Please submit reports via the [Report a vulnerability](https://github.com/veraPDF/veraPDF-validation/security/advisories/new) button.
+
+
+Please provide the following information in your report:
+
+- A description of the vulnerability and its impact
+- How to reproduce the issue
+
+Please allow us 90 days to work on a fix before public disclosure.
