Improper header name validation in guzzlehttp/psr7
Quick fix
GHSA-wxmh-65f7-jcvw — guzzlehttp/psr7: upgrade to the fixed version with the command below.
composer require guzzlehttp/psr7:^1.9.1Details
### 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.
