This security bulletin contains information about 2 vulnerabilities.

1) Server-Side Request Forgery (SSRF)

EUVDB-ID: #VU49041

Risk: Medium

CVSSv4.0: 5.5 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:L/SI:N/SA:N/E:P/U:Green]

CVE-ID: CVE-2020-26258

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