In PHP 8.0.X before 8.0.28, 8.1.X before 8.1.16 and 8.2.X before 8.2.3, password_verify() function may accept some invalid Blowfish hashes as valid. If such invalid hash ever ends up in the password database, it may lead to an application allowing any password for this entry as valid.

CVE-2023-0567 PHP vulnerability
Title: PHP vulnerability
Summary: PHP could be made to bypass password checking if a specially crafted input was
provided.
It was discovered that PHP incorrectly handled certain invalid Blowfish
password hashes. An invalid password hash could possibly allow applications to
accept any password as valid, contrary to expectations.
Instructions: In general, a standard system update will make all the necessary changes.

php: Password_verify() always return true with some hash
In PHP 8.0.X before 8.0.28, 8.1.X before 8.1.16 and 8.2.X before 8.2.3, password_verify() function may accept some invalid Blowfish hashes as valid. If such invalid hash ever ends up in the password database, it may lead to an application allowing any password for this entry as valid.
A vulnerability was found in PHP. This security flaw occurs when malformatted BCrypt hashes that include a $ within their salt part trigger a buffer overread and may erroneously validate any password as valid.

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
