VLAI
Summary
Regular Expression Denial of Service in Headers
Details

Impact

The Headers.set() and Headers.append() methods are vulnerable to Regular Expression Denial of Service (ReDoS) attacks when untrusted values are passed into the functions. This is due to the inefficient regular expression used to normalize the values in the headerValueNormalize() utility function.

Patches

This vulnerability was patched in v5.19.1.

Workarounds

There is no workaround. Please update to an unaffected version.
