Summary

Parse Server before 8.6.97 and 9.0.0 before 9.10.2-alpha.6 does not handle errors raised while sending verification or password reset emails, causing the server process to exit. A client holding only the public application keys can sign up, request a verification email, or request a password reset while the mail provider rejects, rate limits, or is unavailable, crashing the server.

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.
