The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - PHPUnit is a testing framework for PHP. A vulnerability has been discovered in versions prior to 12.5.8,     11.5.50, 10.5.62, 9.6.33, and 8.5.52 involving unsafe deserialization of code coverage data in PHPT test     execution. The vulnerability exists in the `cleanupForCoverage()` method, which deserializes code coverage     files without validation, potentially allowing remote code execution if malicious `.coverage` files are     present prior to the execution of the PHPT test. The vulnerability occurs when a `.coverage` file, which     should not exist before test execution, is deserialized without the `allowed_classes` parameter     restriction. An attacker with local file write access can place a malicious serialized object with a     `__wakeup()` method into the file system, leading to arbitrary code execution during test runs with code     coverage instrumentation enabled. This vulnerability requires local file write access to the location     where PHPUnit stores or expects code coverage files for PHPT tests. This can occur through CI/CD pipeline     attacks, the local development environment, and/or compromised dependencies. Rather than just silently     sanitizing the input via `['allowed_classes' => false]`, the maintainer has chosen to make the anomalous     state explicit by treating pre-existing `.coverage` files for PHPT tests as an error condition. Starting     in versions in versions 12.5.8, 11.5.50, 10.5.62, 9.6.33, when a `.coverage` file is detected for a PHPT     test prior to execution, PHPUnit will emit a clear error message identifying the anomalous state.
    Organizations can reduce the effective risk of this vulnerability through proper CI/CD configuration,     including ephemeral runners, code review enforcement, branch protection, artifact isolation, and access     control. (CVE-2026-24765)

Note that Nessus relies on the presence of the package as reported by the vendor.

    PHPUnit is a testing framework for PHP. A vulnerability has been     discovered involving unsafe deserialization of code coverage data in     PHPT test execution. The vulnerability exists in the     `cleanupForCoverage()` method, which deserializes code coverage files     without validation, potentially allowing remote code execution if     malicious `.coverage` files are present prior to the execution of the     PHPT test.

    For Debian 11 bullseye, this problem has been fixed in version     9.5.2-1+deb11u1.

    We recommend that you upgrade your phpunit packages.
