Title
PHPUnit vulnerable to code execution by other local users via shared temporary directory in PHPT code coverage handling
Summary
PHPUnit is a testing framework for PHP. From 13.4.0 until 13.4.4, the TestCase::coverageFilesDirectory() logic in src/Runner/Phpt/TestCase.php creates temporary files for PHPT code coverage in a predictable phpunit-phpt directory under sys_get_temp_dir() and reuses that directory without verifying its ownership or permissions. On multi-user systems with a shared temporary path, a local attacker who creates the directory before the developer runs PHPT tests with code coverage can replace the generated job file before the child process executes it with require, allowing arbitrary code execution with the developer's privileges while the test and coverage report appear successful. PHPUnit 12.5 and earlier, default macOS and Windows configurations with per-user temporary directories, and single-user environments where another user cannot create files in the temporary path are not affected. This issue is fixed in 13.4.4.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
