medium Tenable Self-Hosted Container Security Plugin ID 400033

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In PHP versions 7.3.x below 7.3.33, 7.4.x below 7.4.26 and 8.0.x below 8.0.13, certain XML parsing
functions, like simplexml_load_file(), URL-decode the filename passed to them. If that filename contains

interpreting the filename differently from what the user intended, which may lead it to reading a
different file than intended. (CVE-2021-21707)
