Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Ghost, the npm package ghost, is vulnerable in versions 2.5.0 up to 6.64.0. An attacker who can get a URL from their own website embedded in content can cause untrusted scripts to be stored in post content, which may run in the Ghost editor, on the published site, and in newsletter emails, possibly compromising a staff user's admin session. Upgrade to version 6.64.0, which contains the fix.
