CVE-2019-11455
A buffer over-read in Util_urlDecode in util.c in Tildeslash Monit before 5.25.3 allows a remote authenticated attacker to retrieve the contents of adjacent memory via manipulation of GET or POST parameters.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.88%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
