CVE-2026-103275
Ghost 5.42.2 before 6.58.0 contains an information disclosure vulnerability in the Admin API bulk post and page edit and delete endpoints, which accept filters on restricted fields such as authors.password, because of an incomplete fix for CVE-2026-70590.
Does this matter?
Lower severity and a low EPSS score (0.21%). Track it; it rarely justifies an emergency change on its own.
Description

Staff-level attackers can infer other staff users' password hashes from which filters match and perform offline password-guessing attacks against them.
