Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Server-Side Request Forgery (SSRF)

EUVDB-ID: #VU119120

Risk: Low

CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N/E:U/U:Clear]

CVE-ID: CVE-2025-20388

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

Exploit availability: No

Description

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

The vulnerability exists due to insufficient validation of user-supplied input. A remote privileged 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.

Mitigation

Install updates from vendor's website.

Vulnerable software versions
