CVE-2010-2531 is a vulnerability of currently unknown severity. The var_export function in PHP 5.2 before 5.2.14 and 5.3 before 5.3.3 flushes the output buffer to the user when certain fatal errors occur, even if display_errors is off, which allows remote attackers to obtain sensitive information by causing the application to exceed limits for memory, execution time, or recursion.. EPSS estimates a 5.00% chance of exploitation in the next 30 days.
