Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'), where the product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. In Floriangaerber/magnesium, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

** UNSUPPORTED WHEN ASSIGNED ** ** UNSUPPORTED WHEN ASSIGNED ** A vulnerability was found in Magnesium-PHP up to 0.3.0. It has been classified as problematic.
