Package : phpunit Version : 9.5.2-1+deb11u1 CVE ID : CVE-2026-24765

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.

For the detailed security status of phpunit please refer to its security tracker page at:
