CVE-2025-22871 (GCVE-0-2025-22871)

Vulnerability from cvelistv5 – Published: 2025-04-08 20:04 – Updated: 2026-05-12 12:04

Title

Request smuggling due to acceptance of invalid chunked data in net/http

Summary

The net/http package improperly accepts a bare LF as a line terminator in chunked data chunk-size lines. This can permit request smuggling if a net/http server is used in conjunction with a server that incorrectly accepts a bare LF as part of a chunk-ext.

Severity

9.1 (Critical)
