Description
This security bulletin contains information about 1 vulnerability.
1) Input validation error (CVE-ID: CVE-2026-47219)
CWE-ID: CWE-20 - Improper input validation
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 an unauthenticated remote attacker to crash a server and cause denial of service when find-my-way is used with Node's HTTP/2 server.
The vulnerability exists due to find-my-way resolving inherited object properties during routing lookups for attacker-controlled HTTP/2 method values. An unauthenticated remote attacker can send a request with a method such as constructor to trigger a crash during routing.
