Description

This security bulletin contains information about 7 vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2026-9320)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: 8.2 [CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


2) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2026-8646)

CWE-ID: CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')

CVSSv4: 9.1 [CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.

The vulnerability exists due to improper validation of HTTP requests. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.

Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.


3) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2026-11541)

CWE-ID: CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')

CVSSv4: 9.1 [CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.

The vulnerability exists due to improper validation of HTTP requests. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.

Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.


4) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2026-11806)

CWE-ID: CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')

CVSSv4: 8.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote privileged user to perform HTTP request smuggling attacks.

The vulnerability exists due to improper validation of HTTP requests with the restConnector-2.0 feature enabled. A remote privileged user can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.

Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.


5) Resource exhaustion (CVE-ID: CVE-2026-9071)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: 8.7 [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]


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


6) Resource exhaustion (CVE-ID: CVE-2026-4410)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: 5.9 [CVSS:4.0/AV:A/AC:H/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows an adjacent user to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources. An adjacent user can trigger resource exhaustion and perform a denial of service (DoS) attack by sending a specially-crafted request.


7) Security features bypass (CVE-ID: CVE-2026-5516)

CWE-ID: CWE-254 - Security Features

CVSSv4: 5.9 [CVSS:4.0/AV:N/AC:H/AT:N/PR:H/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote privileged attacker to gain access to potentially sensitive information.

The vulnerability exists due to excessive data output by the application. A remote privileged attacker can gain unauthorized access to sensitive information on the system.
