Wordfence advisory
medium · CVSS 5.3guzzlehttp/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. While some WordPress plugins and themes may be using this library, it does not make them vulnerable to exploitation.
Severity vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N

How do I check which product and version this report affects?
This report covers more than one product. Choose your plugin, theme or WordPress core in the version checker, then enter its installed version. Each product has its own affected ranges and fix details in the report above.
Which update should I install?
Find your exact product in the report and read its fixed versions and recommended action. Fix details for one product do not apply to every product covered by this advisory. Follow the linked source when no fixed version is specified.
Does an affected version mean my website has been hacked?
An affected version means the installed release matches a vulnerability described in this report. It does not show whether anyone has exploited it on your website. The checker compares version numbers with stored reports; it does not inspect your website.
Does a version outside these ranges mean my website is secure?
A version outside the reported ranges is not listed as affected by this particular issue. Other vulnerabilities, missing information or a previous compromise still need separate checks. Review other reports for your product and keep your website maintained.
