Date: 2022-05
Affected: rubygems/fat_free_crm
Attack vector: xss
Category: vulnerability-disclosure
Severity: Medium
CVE: CVE-2019-10226

CVSS: 5.4 (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N)

## Withdrawn This advisory has been withdrawn because the CVE has been disputed and the underlying vulnerability is likely invalid. This link is maintained to preserve external references. [According to maintainers of Fat Free CRM](https://github.com/github/advisory-database/pull/3599), the CRM comment feature allows certain HTML markup, but santizes the output when rendered to page. This allows safe tags (such as `<h1>` which the author tested and reported as a vulnerability) but correctly disallows `<script>` tags and other dangerous entities. ## Original Description HTML Injection has been discovered in the v0.19.0 version of the Fat Free CRM product via an authenticated request to the /comments URI.
