CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to an infinite loop in the domino HTML parser when processing untrusted HTML containing an incomplete DOCTYPE declaration ending with whitespace before end of file. A remote attacker can submit a crafted incomplete DOCTYPE declaration to cause a denial of service.

The synchronous loop can starve the Node.js event loop and cause the server process to stop responding to requests.
