CVE-2026-76876
Craftplan < 0.5.1 Broken Access Control Information Disclosure via Settings API
Description
Craftplan before 0.5.1 contains a broken access control vulnerability that allows unauthenticated attackers to read sensitive credentials by exploiting an unconditional authorization policy on the Settings resource. Attackers can send a GET request to the settings API endpoint with a valid record ID to retrieve decrypted SMTP passwords, email API keys, and email API secrets due to the read policy using an always-allow authorization check that bypasses all identity verification.
