Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Security features bypass
EUVDB-ID: #VU62314
Risk: Medium
CVSSv4.0: 5.5 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:P/U:Green]
CVE-ID: CVE-2022-22968
CWE-ID:
CWE-254 - Security Features
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to patterns for disallowedFields on a DataBinder are case sensitive, which means a field is not effectively protected unless it is listed
with both upper and lower case for the first character of the field,
including upper and lower case for the first character of all nested
fields within the property path. A remote attacker can bypass implemented security restrictions by passing case sensitive data to the application.

2) Resource exhaustion
EUVDB-ID: #VU62472
Risk: Medium
CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2022-22969
