  - guzzlehttp/psr7 is a PSR-7 HTTP message library. Versions prior to 1.8.4 and 2.1.1 are vulnerable to
    improper header parsing. An attacker could sneak in a new line character and pass untrusted values. The
    issue is patched in 1.8.4 and 2.1.1. There are currently no known workarounds. (CVE-2022-24775)

  - 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. (CVE-2023-29197)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
