Why this matters
Unauthenticated requests can reach limited internal HTTP endpoints without returning response data.
CVSS 3.1: 4 (MEDIUM). Source: CVE assigning authority.
A severity score describes the vulnerability, not the probability that your own website has been compromised. Exposure depends on the installed version, configuration and reachable code path.
When to check your system
Ghost >=6.54.1 and <6.65.0.
How to address it
Fixed in Ghost 6.65.0; use a supported release containing subsequent fixes too.
Record the installed package and vendor build, check the advisory’s prerequisites, back up, apply the vendor fix and test the affected site functions. Distribution packages may include backported fixes without changing the upstream version number.
