Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Command Injection (CVE-ID: CVE-2026-0768)
The vulnerability allows a remote attacker to execute arbitrary commands on the system.
The vulnerability exists due to insufficient input validation within the handling of the code parameter provided to the validate endpoint. A remote attacker can pass specially crafted data to the application and execute arbitrary commands.
2) Deserialization of Untrusted Data (CVE-ID: CVE-2026-0772)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data within the disk cache service. A remote user can pass specially crafted data to the application and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Code Injection (CVE-ID: CVE-2026-0771)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to improper input validation within the handling of Python function components. A remote user can and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Inclusion of Functionality from Untrusted Control Sphere (CVE-ID: CVE-2026-0770)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to inclusion of functionality from untrusted control sphere within the handling of the exec_globals parameter provided to the validate endpoint. A remote attacker can execute arbitrary code on the system.
5) Command Injection (CVE-ID: CVE-2026-0769)
The vulnerability allows a remote attacker to execute arbitrary commands on the system.
The vulnerability exists due to insufficient input validation within the implementation of eval_custom_component_code function. A remote attacker can pass specially crafted data to the application and execute arbitrary commands.
