Summary
Improper header name validation in guzzlehttp/psr7
Details

Impact

Improper header parsing. An attacker could sneak in a newline (\n) into both the header names and values. While the specification states that \r\n\r\n is used to terminate the header list, many servers in the wild will also accept \n\n.

Patches

The issue is patched in 1.9.1 and 2.4.5.

Workarounds

There are no known workarounds.
