CVE-2025-7080 in Jank
Summary
by MITRE • 07/06/2025
A vulnerability, which was classified as problematic, was found in Done-0 Jank up to 322caebbad10568460364b9667aa62c3080bfc17. Affected is an unknown function of the file internal/utils/jwt_utils.go of the component JWT Token Handler. The manipulation of the argument accessSecret/refreshSecret with the input jank-blog-secret/jank-blog-refresh-secret leads to use of hard-coded password. It is possible to launch the attack remotely. The complexity of an attack is rather high. The exploitability is told to be difficult. The exploit has been disclosed to the public and may be used. Continious delivery with rolling releases is used by this product. Therefore, no version details of affected nor updated releases are available.

This vulnerability resides within the JWT token handling functionality of the Done-0 Jank application, specifically in the internal/utils/jwt_utils.go file where the JWT Token Handler component processes authentication tokens. The flaw manifests when the system utilizes hard-coded secret values for accessSecret and refreshSecret parameters, with the specific hardcoded values being jank-blog-secret and jank-blog-refresh-secret respectively. This represents a critical security weakness that violates fundamental principles of secure credential management and authentication system design. The vulnerability has been classified as problematic with a high attack complexity rating, indicating that while exploitation is possible, it requires significant technical expertise and resources to execute successfully. The attack vector is remote, meaning that an adversary can potentially exploit this weakness without requiring physical access to the target system.
The technical implementation flaw stems from the application's use of hardcoded cryptographic secrets within the JWT token generation and validation processes. This approach directly contravenes security best practices and industry standards such as those outlined in CWE-312 (Cleartext Storage of Sensitive Information) and CWE-798 (Use of Hard-coded Credentials). When authentication tokens are generated using predictable, hardcoded secrets, attackers can easily derive these values and subsequently forge valid tokens, leading to unauthorized access to protected resources. The use of rolling release deployment strategies in this product complicates remediation efforts as the exact vulnerable versions remain unspecified, creating uncertainty for security teams attempting to assess their risk exposure. This lack of version information also suggests potential issues with the product's release management and security patching processes, which can leave systems exposed for extended periods.
The operational impact of this vulnerability extends beyond simple unauthorized access, as it fundamentally undermines the security model of the entire authentication system. Successful exploitation could enable attackers to impersonate legitimate users, access sensitive data, modify system configurations, or potentially escalate privileges within the application environment. The difficulty of exploitability, while providing some defensive complexity, does not eliminate the serious risk posed by hardcoded secrets that are publicly disclosed. The fact that exploit information has been made publicly available further compounds the risk, as it provides malicious actors with detailed guidance on how to leverage this weakness. Organizations using this software must urgently assess their exposure and implement immediate mitigations, as the rolling release deployment model suggests that vulnerable versions may still be actively running in production environments without proper version tracking or security monitoring in place.
Mitigation strategies should focus on immediate credential rotation and implementation of proper secret management practices. Organizations must replace the hardcoded jank-blog-secret and jank-blog-refresh-secret values with dynamically generated, securely stored credentials using established secret management solutions such as HashiCorp Vault, AWS Secrets Manager, or similar platforms. The application architecture should be reviewed to eliminate hardcoded credentials entirely and implement proper environment variable injection or secure configuration management. Additionally, security teams should implement comprehensive monitoring for unauthorized access attempts and conduct thorough penetration testing to identify any additional weaknesses in the authentication infrastructure. The vulnerability highlights the critical importance of following security frameworks such as NIST SP 800-53 controls for secure configuration management and the MITRE ATT&CK framework's focus on credential access techniques, particularly those involving hard-coded credentials and token manipulation. Regular security assessments and vulnerability scanning should be implemented to prevent similar issues from emerging in future releases, while also ensuring that the rolling release process includes proper security validation and version control mechanisms.
