Hi,

The following vulnerability was published for php-guzzlehttp-psr7.

CVE-2023-29197[0]:
| guzzlehttp/psr7 is a PSR-7 HTTP message library implementation in PHP.
| Affected versions are subject to 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. This is a
| follow-up to CVE-2022-24775 where the fix was incomplete. The issue
| has been patched in versions 1.9.1 and 2.4.5. There are no known
| workarounds for this vulnerability. Users are advised to upgrade.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
