Details

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. ### References * https://www.rfc-editor.org/rfc/rfc7230#section-3.2.4
