High impact if exploited, but EPSS currently rates exploitation as unlikely (3.28%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

ELOG 3.1.4-57bea22 and below is affected by a denial of service vulnerability due to a use after free. A remote unauthenticated attacker can crash the ELOG server by sending multiple HTTP POST requests which causes the ELOG function retrieve_url() to use a freed variable.
