Tracked as CVE-2022-41654 (CVSS score: 8.5), the authentication bypass vulnerability that allows unprivileged people (i.e., associates) to make unauthorized modifications to newsletter settings.
Cisco Talos, which found the shortcoming, said it could enable a member to transform the program-wide default e-newsletter that all consumers are subscribed to by default.
“This provides unprivileged people the means to check out and adjust configurations they had been not supposed to have accessibility to,” Ghost mentioned in an advisory released on November 28, 2022. “They are not equipped to escalate their privileges completely or get access to even further info.”
The CMS system blamed the bug owing to a “hole” in its API validation, introducing it found no proof that the issue has been exploited in the wild.
Also patched by Ghost is an enumeration vulnerability in the login operation (CVE-2022-41697, CVSS score: 5.3) that could guide to the disclosure of sensitive information and facts.
For each Talos, this flaw could be leveraged by an attacker to enumerate all legitimate customers of Ghost by giving an email tackle, which could then be made use of to slim down opportunity targets for a upcoming-phase phishing attack.
The flaws have been addressed in the Ghost (Pro) managed hosting service, but end users who self-host the company and operate a version involving 4.46. and 4.48.7 or any variation of v5 up to and such as 5.22.6 are required to update to variations 4.48.8 and 5.22.7.
