SCA: security update for github.com/ewen-lbh/ffcss (GHSA-wpmx-564x-h2mh)

medium Tenable Self-Hosted Container Security Plugin ID 420043

Description

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

 - ffcss is a CLI interface to apply and configure Firefox CSS themes. Prior to 0.2.0, the function
 `lookupPreprocess()` is meant to apply some transformations to a string by disabling characters in the
 regex `[-_ .]`. However, due to the use of late Unicode normalization of type NFKD, it is possible to
 bypass that validation and re-introduce all the characters in the regex `[-_ .]`. The `lookupPreprocess()`
 can be easily bypassed with equivalent Unicode characters like U+FE4D (﹍), which would result in the
 omitted U+005F (_), for instance. The `lookupPreprocess()` function is only ever used to search for themes
 loosely (case insensitively, while ignoring dashes, underscores and dots), so the actual security impact
 is classified as low. This vulnerability is fixed in 0.2.0. There are no known workarounds.
 (CVE-2023-52081)
