Summary

CVE-2023-52081 is a vulnerability that affects the CLI interface ffcss, used to apply and configure Firefox CSS themes. The vulnerability exists in versions prior to 0.2.0 and is related to the function lookupPreprocess(). This function is meant to disable certain characters in a string using a regex, but due to the use of late Unicode normalization, it is possible to bypass this validation and reintroduce those characters. The impact of this vulnerability is classified as low because the lookupPreprocess() function is only used for loosely searching themes. The vulnerability has been fixed in version 0.2.0, and there are no known workarounds available. The affected products include uFhhOd, uFhhOf, uFhhOe, and usBOMS.
