CVE-2021-44140
Remote attackers may delete arbitrary files in a system hosting a JSPWiki instance, versions up to 2.11.0.M8, by using a carefuly crafted http request on logout, given that those files are reachable to the user running the JSPWiki instance.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.16%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
