CVE-2026-76876: Missing Authorization in puemos craftplan
Craftplan versions before 0.5.1 have a broken access control vulnerability that allows unauthenticated attackers to read sensitive credentials. The flaw exists because the Settings resource uses an unconditional authorization policy, permitting any attacker to retrieve decrypted SMTP passwords, email API keys, and secrets by sending a GET request with a valid record ID. This bypasses all identity verification and exposes critical configuration data.
AI Analysis
Technical Summary
CVE-2026-76876 is a broken access control vulnerability in puemos craftplan prior to version 0.5.1. The vulnerability arises from an always-allow authorization check on the Settings resource's read policy, which does not verify the identity of the requester. As a result, unauthenticated attackers can send GET requests to the settings API endpoint with valid record IDs to obtain decrypted sensitive credentials such as SMTP passwords and email API keys and secrets. This flaw compromises the confidentiality of critical configuration data.
Potential Impact
The vulnerability allows unauthenticated attackers to access sensitive credentials including SMTP passwords and email API keys and secrets. This exposure can lead to unauthorized use of email services and potentially further compromise of the affected environment. The CVSS 4.0 base score is 8.2 (high severity), reflecting the network attack vector, no privileges required, no user interaction, and high impact on confidentiality.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or patch link is provided, users should monitor vendor communications for updates. Until a fix is available, restrict access to the settings API endpoint and implement compensating controls to protect sensitive credentials.
