^10.2 || ^11.0 || ^12.0→^13.0PHPUnit Vulnerable to Unsafe Deserialization in PHPT Code Coverage Handling
CVE-2026-24765 / GHSA-vvj3-c3rp-c85p
More information
Details
Overview
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.coveragefiles are present prior to the execution of the PHPT test.Technical Details
Affected Component: PHPT test runner, method
cleanupForCoverage()Affected Versions: <= 8.5.51, <= 9.6.32, <= 10.5.61, <= 11.5.49, <= 12.5.7
Vulnerable Code Pattern
The vulnerability occurs when a
.coveragefile, which should not exist before test execution, is deserialized without theallowed_classesparameter 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.Attack Prerequisites and Constraints
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:
.coveragefile alongside test files, executed when the CI system runs tests using PHPUnit and collects code coverage informationCritical Context: Running test suites from unreviewed pull requests without isolated execution is inherently a code execution risk, independent of this specific vulnerability. This represents a broader class of Poisoned Pipeline Execution (PPE) attacks affecting CI/CD systems.
Proposed Remediation Approach
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.coveragefiles for PHPT tests as an error condition.Rationale for Error-Based Approach:
.coveragefile existing before test execution), the error must be visible in CI/CD output, alerting operators to investigate the root cause rather than proceeding with sanitized input.coveragefile should never exist before tests run, coverage data is generated by executing tests, not sourced from artifacts. Its presence indicates:Severity Classification
Mitigating Factors (Environmental Context)
Organizations can reduce the effective risk of this vulnerability through proper CI/CD configuration:
Fixed Behaviour
When a
.coveragefile is detected for a PHPT test prior to execution, PHPUnit will emit a clear error message identifying the anomalous state. This ensures:Recommendation
Update to the patched version immediately if a project runs PHPT tests using PHPUnit with coverage instrumentation in any CI/CD environment that executes code from external contributors. Additionally, audit the project's CI/CD configuration to ensure:
