Security Advisories: GSA_kwCzR0hTQS13eG1oLTY1ZjctamN2d84AAy3w
Improper header name validation in guzzlehttp/psr7
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.
