Summary
Ghost from 2.5.0 before 6.64.0 contains a stored cross-site scripting vulnerability that allows attackers to inject untrusted scripts into post content via oEmbed photo responses. Attackers can host malicious oEmbed photo responses so that embedding their URL stores scripts that run in the Ghost editor, published site, and newsletter emails, compromising staff admin sessions.

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.
