Summary
Password Pusher, an open source application to communicate sensitive information over the web, comes with a configurable rate limiter. In versions prior to v1.49.0, the rate limiter could be bypassed by forging proxy headers allowing bad actors to send unlimited traffic to the site potentially causing a denial of service. In v1.49.0, a fix was implemented to only authorize proxies on local IPs which resolves this issue. As a workaround, one may add rules to one's proxy and/or firewall to not accept external proxy headers such as `X-Forwarded-*` from clients.

Fencer Intel 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.
