medium Nessus Plugin ID 318691

Synopsis

The version PHP running on the remote web server is affected by multiple vulnerabilities.

Description

The version of PHP installed on the remote host is prior to 8.5.7. It is, therefore, affected by multiple vulnerabilities as referenced in the Version 8.5.7 advisory.

 - In uriparser before 1.0.2, the function family EqualsUri can misclassify two unequal URIs as equal.
 (CVE-2026-44928)

 - In uriparser before 1.0.2, there is pointer difference truncation to int in various places.

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

Solution

Upgrade to PHP version 8.5.7 or later.
