CVE-2026-1197 is an information disclosure vulnerability identified in MineAdmin versions 1.x and 2.x. The vulnerability resides in an unspecified functionality of the /system/downloadById endpoint, where manipulation of the ID argument can cause unauthorized disclosure of information. The exact nature of the leaked data is not detailed, but the exposure could involve sensitive internal data accessible via this endpoint. The vulnerability can be triggered remotely without user interaction, but exploitation requires a high level of complexity and only low privileges, indicating that an attacker with limited access could potentially leverage this flaw. The CVSS 4.0 vector indicates network attack vector (AV:N), high attack complexity (AC:H), no privileges required (PR:L), no user interaction (UI:N), and low impact on confidentiality (VC:L), with no impact on integrity or availability. The vendor was contacted early but did not respond or issue patches, leaving the vulnerability unmitigated officially. Although no exploits are currently observed in the wild, the exploit code is publicly available, increasing the risk of future attacks. This vulnerability highlights a risk in MineAdmin's handling of input parameters and insufficient access control or validation in the downloadById functionality, potentially allowing attackers to retrieve unauthorized information remotely.

The primary impact of CVE-2026-1197 is unauthorized information disclosure, which could lead to leakage of sensitive data stored or accessible via the /system/downloadById endpoint in MineAdmin. While the confidentiality impact is rated low, the exposure of internal data could facilitate further attacks such as social engineering, reconnaissance, or privilege escalation. The vulnerability does not affect integrity or availability, limiting the scope of damage. However, organizations relying on MineAdmin for administrative or operational functions may face risks related to data privacy compliance and potential reputational damage if sensitive information is leaked. The high complexity of exploitation and low privileges required mean that only skilled attackers with some access could exploit this, reducing the likelihood of widespread attacks. The lack of vendor response and patches increases the window of exposure. Overall, the threat is moderate but should not be ignored, especially in environments where MineAdmin is critical and contains sensitive information.

Given the absence of official patches or vendor response, organizations should implement compensating controls to mitigate this vulnerability. First, restrict network access to the MineAdmin management interface and specifically to the /system/downloadById endpoint using firewalls, VPNs, or IP whitelisting to limit exposure to trusted users only. Second, implement strict access controls and authentication mechanisms to ensure only authorized personnel can access MineAdmin features, minimizing the risk of low-privilege exploitation. Third, monitor logs and network traffic for unusual or repeated access attempts to the downloadById endpoint, which may indicate exploitation attempts. Fourth, consider deploying web application firewalls (WAFs) with custom rules to detect and block suspicious parameter manipulations targeting the ID argument. Fifth, conduct internal code reviews or penetration tests to identify and remediate similar input validation weaknesses in MineAdmin or related systems. Finally, maintain an incident response plan ready to address any detected exploitation and keep abreast of any future vendor updates or patches.
