1) Resource exhaustion
EUVDB-ID: #VU56963
Risk: Medium
CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-3749
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a regular expression denial of service (ReDoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources within the isURLSearchParams function in utils.js. A remote attacker can send specially crafted data to the application and perform regular expression denial of service (ReDoS) attack.
MitigationInstall update from vendor's website.

2) Server-Side Request Forgery (SSRF)
EUVDB-ID: #VU49251
Risk: Medium
CVSSv3.1: 6.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2020-28168
CWE-ID:
CWE-918 - Server-Side Request Forgery (SSRF)
Exploit availability: No
DescriptionThe disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker is able to bypass a proxy by providing a URL that responds with a redirect to a restricted host or IP address 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.
