Summary

Soft Serve is a self-hostable Git server for the command line. In versions prior to 0.10.0, there are several places where the user can insert data (e.g. names) and ANSI escape sequences are not being removed, which can then be used, for example, to show fake alerts. In the same token, git messages, when printed, are also not being sanitized. This issue is fixed in version 0.10.0.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
