Description
This security bulletin contains information about 1 vulnerability.
1) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2025-55702)
CWE-ID: CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')
CVSSv4: 9.1 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to smuggle requests past a front-end proxy and desynchronize responses for other users.
The vulnerability exists due to improper HTTP request framing in Apache Traffic Server when an origin responds to a POST with Expect: 100-continue before reading its body, leaving the unread body to be parsed as another request. A remote attacker can send a crafted POST through a front-end proxy that shares connections to Traffic Server to smuggle a request past the front end and desynchronize other users' responses.
