CVE-2022-32214
The llhttp parser <v14.20.1, <v16.17.1 and <v18.9.1 in the http module in Node.js does not strictly use the CRLF sequence to delimit HTTP requests.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 81.8%, higher than 100% of all known CVEs. Patch or mitigate before the next change window.
