CVE-2026-63100: Missing Authorization in maybe-finance maybe
Maybe through 0.6.0 contains a missing authorization vulnerability that allows authenticated low-privilege member-role users to access and modify global hosting settings by exploiting unprotected show and update actions in the Settings::HostingsController, where the before_action ensure_admin filter is applied only to the clear_cache action. Attackers can read the operator's Synth API key rendered in plaintext via a form field value attribute, overwrite it with an attacker-controlled value, toggle public registration settings, and disable email confirmation requirements to disrupt the entire instance.
AI Analysis
Technical Summary
CVE-2026-63100 describes a missing authorization vulnerability in maybe-finance's maybe product up to version 0.6.0. Authenticated users with low-privilege member roles can exploit unprotected show and update actions in the Settings::HostingsController, as the ensure_admin before_action filter is only applied to the clear_cache action. This allows attackers to read the operator's Synth API key in plaintext, overwrite it with arbitrary values, and modify critical global hosting settings such as public registration and email confirmation requirements, leading to significant security and operational impact.
Potential Impact
An attacker with low-privilege authenticated access can read sensitive API keys and modify global hosting settings, including disabling email confirmation and toggling public registration. This can lead to unauthorized access, potential account takeover, and disruption of the entire maybe instance's normal operation.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to member-role users or apply additional access controls to the affected controller actions to prevent unauthorized modifications.
