This can lead to discrepancies between the host returned by Uri::getHost() and the actual URI authority, potentially compromising security or routing decisions. Developers using versions prior to 2.12.3 should prioritize updating to mitigate risks associated with this flaw.

Original NVD Description
guzzlehttp/psr7 is a PSR-7 HTTP message library implementation in PHP. Prior to 2.12.3, Uri::assertValidHost() does not reject URI host components containing authority delimiters, embedded ports, or malformed IPv6 brackets, allowing Uri::getHost() to disagree with the URI authority used for security or routing decisions. This issue is fixed in version 2.12.3.
