SCA: security update for external-svg-loader (GHSA-xc2r-jf2x-gjr8)

medium Tenable Cloud Security Plugin ID 420417

Description

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

- SVG Loader is a javascript library that fetches SVGs using XMLHttpRequests and injects the SVG code in the
tag's place. According to the docs, svg-loader will strip all JS code before injecting the SVG file for
security reasons but the input sanitization logic is not sufficient and can be trivially bypassed. This
allows an attacker to craft a malicious SVG which can result in Cross-site Scripting (XSS). When trying to
sanitize the svg the lib removes event attributes such as `onmouseover`, `onclick` but the list of events
is not exhaustive. Any website which uses external-svg-loader and allows its users to provide svg src,
upload svg files would be susceptible to stored XSS attack. This issue has been addressed in commit
`d3562fc08` which is included in releases from 1.6.9. Users are advised to upgrade. There are no known
workarounds for this vulnerability. (CVE-2023-40013)
