An information leak vulnerability was found in Undertow.
MEDIUM 5.3EPSS 2.11%
Does this matter?
Lower severity and a low EPSS score (2.11%). Track it; it rarely justifies an emergency change on its own.
Description
An information leak vulnerability was found in Undertow. If all headers are not written out in the first write() call then the code that handles flushing the buffer will always write out the full contents of the writevBuffer buffer, which may contain data from previous requests.
