• Packagist nyholm/psr7: < 1.6.1 → fixed in 1.6.1
Description
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 1.6.1.
Workarounds
There are no known workarounds.
