Description

This security bulletin contains information about 1 vulnerability.


1) Deserialization of Untrusted Data (CVE-ID: CVE-2026-24765)

CWE-ID: CWE-502 - Deserialization of Untrusted Data

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to execute arbitrary code.

The vulnerability exists due to deserialization of untrusted data in the cleanupForCoverage() method of the PHPT test runner when processing a pre-existing .coverage file during PHPT test execution with code coverage instrumentation enabled. A local user can place a malicious serialized object in a .coverage file to execute arbitrary code.

The issue is triggered only if a .coverage file is present before test execution.
