GHSA-V7MG-WG5H-PCX8

Vulnerability from github – Published: 2022-05-13 01:32 – Updated: 2022-05-13 01:32

Details

Multipart-file uploads call variables to be improperly registered in the global scope. In cases where variables are not declared explicitly before being used this can lead to unexpected behavior. This affects all supported versions of HHVM prior to the patch (3.25.1, 3.24.5, and 3.21.9 and below).

Severity ?

9.8 (Critical)
