The analysis of the vulnerability and the provided patch points directly to the dol_eval function as the source of the remote code execution vulnerability. The vulnerability description specifies that a 'computed field parameter' is the injection point, and the patch commit b03f30c7e27fb89dbfb15902dbf4619ae77f0f86 focuses exclusively on hardening the dol_eval function in htdocs/core/lib/functions.lib.php. The commit message, 'Sec: Remove functions accepting callable params', and the extensive additions to the function blacklist within dol_eval confirm that the vulnerability was due to an incomplete blacklist of dangerous functions. The added test cases in test/phpunit/SecurityTest.php further prove that functions like array_map were used to achieve code execution. During an exploit, the user-provided input from the computed field would be processed by dol_eval, making it the key function that would appear in any runtime profile or stack trace.
