The host is installed with PHP versions 7.4.x below 7.4.28, 8.0.x below 8.0.16 or 8.1.x below 8.1.3 and is prone to an use after free vulnerability. A flaw is present in the application, which fails to properly handle issues in the filter functions with FILTER_VALIDATE_FLOAT filter and min/max limits. On successful exploitation, when using filter functions with FILTER_VALIDATE_FLOAT filter and min/max limits, if the filter fails, there is a possibility to trigger use of allocated memory after free, which can result it crashes, and potentially in overwrite of other memory chunks and RCE.
