Description

This security bulletin contains information about 2 vulnerabilities.


1) Server-Side Request Forgery (SSRF) (CVE-ID: N/A)

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N/E:U/U:Green


The disclosed vulnerability allows a remote user to perform SSRF attacks.

The vulnerability exists due to insufficient validation of user-supplied input while executing createMediaItem requests. A remote user can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.

Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.


2) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2023-23684)

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote user to access unintended server resources.

The vulnerability exists due to server-side request forgery in the createMediaItem mutation resolver when processing the filePath argument in GraphQL requests. A remote user can submit a specially crafted mutation with an executable path to access unintended server resources.

Exploitation requires media upload capabilities, such as editor-level access or higher.
