GHSA-2F7V-PJJ3-RVVW
Vulnerability from github – Published: 2026-05-01 18:31 – Updated: 2026-05-01 18:31AGL app-framework-binder (afb-daemon) through v19.90.0 contains a privilege escalation vulnerability in the supervision Do command. The on_supervision_call function in src/afb-supervision.c explicitly nullifies the request credentials by calling afb_context_change_cred(&xreq->context, NULL) before dispatching an attacker-controlled API call via xapi->itf->call(xapi->closure, xreq). The NULL propagation chain through afb-context.c:110 (context->credentials = afb_cred_addref(NULL)) and afb-cred.c:163 (returns NULL when cred is NULL) confirms that credentials are zeroed before the target API executes. The attacker controls both api and verb parameters via JSON input, allowing execution of any registered API with a NULL credential context. APIs that rely on context->credentials for authorization decisions may fail open when receiving NULL credentials, enabling privilege escalation. This vulnerability was introduced in commit abbb4599f0b921c6f434b6bd02bcfb277eecf745 on 2018-02-14.

Mitigation MIT-1
Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
Mitigation MIT-48
Strategy: Separation of Privilege
Follow the principle of least privilege when assigning access rights to entities in a software system.
Mitigation MIT-49
Strategy: Separation of Privilege
Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.
CAPEC-122: Privilege Abuse
An adversary is able to exploit features of the target that should be reserved for privileged users or administrators but are exposed to use by lower or non-privileged accounts. Access to sensitive information and functionality must be controlled to ensure that only authorized users are able to access these resources.
CAPEC-233: Privilege Escalation
An adversary exploits a weakness enabling them to elevate their privilege and perform an action that they are not supposed to be authorized to perform.
CAPEC-58: Restful Privilege Elevation
An adversary identifies a Rest HTTP (Get, Put, Delete) style permission method allowing them to perform various malicious actions upon server data due to lack of access control mechanisms implemented within the application service accepting HTTP messages.
