CVE-2025-7080 is a security vulnerability identified in the Done-0 project's product named Jank, specifically affecting the JWT Token Handler component within the file internal/utils/jwt_utils.go. The vulnerability arises from the use of hard-coded passwords for the accessSecret and refreshSecret parameters, which are set to fixed values 'jank-blog-secret' and 'jank-blog-refresh-secret' respectively. This hard-coding flaw allows an attacker to potentially bypass authentication or forge JWT tokens if they can exploit this secret, undermining the security of token-based authentication mechanisms. The vulnerability is remotely exploitable but has a high attack complexity, meaning that exploitation requires significant effort or specific conditions. No privileges or user interaction are needed to attempt exploitation, but the difficulty level reduces the likelihood of widespread exploitation. The product uses continuous delivery with rolling releases, so no specific version numbers beyond the commit hash are available for affected or patched versions. The CVSS 4.0 base score is 6.3 (medium severity), reflecting network attack vector, high complexity, no privileges required, no user interaction, and limited impact confined to confidentiality. The vulnerability was publicly disclosed on July 6, 2025, but no known exploits are currently reported in the wild. The core issue is the insecure practice of embedding static secrets in source code, which can be extracted by attackers to compromise JWT authentication tokens, potentially leading to unauthorized access or privilege escalation within applications relying on this component.

For European organizations using the Done-0 Jank product, this vulnerability poses a moderate risk primarily to confidentiality and authentication integrity. If exploited, attackers could generate valid JWT tokens, impersonate legitimate users, or gain unauthorized access to protected resources. This could lead to data breaches, unauthorized transactions, or lateral movement within corporate networks. The medium CVSS score and high attack complexity suggest that only skilled attackers with sufficient resources would likely succeed, limiting widespread impact. However, organizations in sectors with stringent data protection requirements (e.g., finance, healthcare, government) could face regulatory and reputational damage if compromised. Since JWT tokens are commonly used for session management and API authentication, the vulnerability could affect web applications, microservices, and cloud-based services relying on Jank. The continuous delivery model may complicate patch management, requiring organizations to monitor updates closely. Overall, the threat is significant but not critical, demanding timely remediation to prevent potential exploitation.

European organizations should immediately audit their use of the Done-0 Jank product to determine exposure to this vulnerability. Specific mitigation steps include: 1) Replace hard-coded secrets with securely generated, environment-specific secrets managed via secure vaults or environment variables rather than embedded in source code. 2) Implement secret rotation policies to periodically update JWT secrets and invalidate existing tokens. 3) Monitor application logs and authentication events for anomalies indicative of token forgery or unauthorized access attempts. 4) Engage with the Done-0 vendor or community to obtain patched versions or updates addressing this issue, given the continuous delivery model. 5) Employ runtime application self-protection (RASP) or Web Application Firewalls (WAF) to detect and block suspicious JWT token usage patterns. 6) Conduct penetration testing focusing on JWT authentication flows to validate the effectiveness of mitigations. 7) Educate developers on secure secret management best practices to prevent recurrence. These targeted actions go beyond generic advice by focusing on secret management, monitoring, and vendor engagement specific to this vulnerability.
