CVE-2022-29404
In Apache HTTP Server 2.4.53 and earlier, a malicious request to a lua script that calls r:parsebody(0) may cause a denial of service due to no default limit on possible input size.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.38%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
