CVE-2026-1193: 
PHP vulnerability analysis and mitigation

CVE-2026-1193 is an improper authorization vulnerability (vertical privilege escalation) in MineAdmin versions 1.x and 2.x, affecting the View Interface component at the /system/cache/view endpoint. The flaw allows low-privileged authenticated users to bypass access controls and access Redis cache data containing highly sensitive information such as administrator tokens and crontab configurations. It was submitted to VulDB on January 8, 2026, published on January 19, 2026, and received NVD initial analysis on February 5, 2026. The CVSS v3.1 base score is 8.8 (High) per NVD, while the CNA (VulDB) rates it 6.3 (Medium) (GitHub PoC, Red Hat CVE).

The vulnerability is classified under CWE-266 (Incorrect Privilege Assignment) and CWE-285 (Improper Authorization). The /system/cache/view endpoint in MineAdmin's View Interface requires authentication (login) but lacks specific permission identifiers or role-based access checks, enabling any authenticated low-privileged user to perform vertical privilege escalation. By sending a crafted POST request to /prod/system/cache/view with a standard user Bearer token, an attacker can directly query the underlying Redis cache, retrieving sensitive keys such as MineAdmin:Token:1 (administrator JWT) and MineAdmin:crontab. A public proof-of-concept demonstrating this technique is available on GitHub (GitHub PoC).

Successful exploitation allows a low-privileged authenticated attacker to access the Redis cache and retrieve administrator JWT tokens, all user session tokens, and crontab configurations — effectively achieving full account takeover of any user including administrators. With a stolen administrator token, an attacker can perform any privileged action within MineAdmin, including modifying system configurations, accessing all managed data, and potentially pivoting to other systems. The CVSS v3.1 score reflects high impact to confidentiality, integrity, and availability (GitHub PoC, Red Hat CVE).

A public proof-of-concept exploit is available on GitHub, published by the researcher SourByte05, demonstrating the full vertical privilege escalation attack with a concrete HTTP request payload. The exploit was added to NVD's reference tracking on February 5, 2026. There is no confirmed evidence of in-the-wild exploitation at this time, and no threat actor attribution has been reported. The EPSS score is approximately 0.034% (0.000340), indicating low but non-zero probability of exploitation in the near term. The vulnerability is not currently listed in the CISA Known Exploited Vulnerabilities (KEV) catalog (GitHub PoC, Red Hat CVE).

1. Reconnaissance: Identify internet-facing MineAdmin v1.x or v2.x instances using asset discovery queries such as body="MineAdmin" on tools like Fofa or Shodan.
2. Obtain a low-privileged account: Register or obtain credentials for any standard (non-admin) user account on the target MineAdmin instance.
3. Authenticate and retrieve a user token: Log in to MineAdmin and capture the Bearer JWT token issued to the low-privileged user.
4. Send crafted POST request: Issue a POST request to /prod/system/cache/view with the low-privileged Bearer token in the Authorization header and a JSON body specifying the target Redis cache key (e.g., MineAdmin:Token:1 for the administrator token):

   POST /prod/system/cache/view HTTP/1.1
   Host: <target>:8888
   Authorization: Bearer <ordinary_user_token>
   Content-Type: application/json;charset=UTF-8
   
   {"key": "MineAdmin:Token:1"}

5. Extract sensitive data: The server returns the Redis cache value, which includes the administrator JWT token, other user tokens, or crontab data — without enforcing any privilege check.
6. Escalate privileges: Use the retrieved administrator JWT token to authenticate as the administrator and perform any privileged action within MineAdmin (GitHub PoC).

• Network: Unusual POST requests to /prod/system/cache/view or /system/cache/view from non-administrative user accounts; repeated cache view requests from the same low-privileged user in a short timeframe.
• Logs: MineAdmin access logs showing authenticated requests to the /system/cache/view endpoint from accounts that do not normally access cache management functions; requests querying Redis keys such as MineAdmin:Token:1 or MineAdmin:crontab.
• Authentication: Subsequent logins or API calls using administrator-level JWT tokens from IP addresses or user agents not associated with the actual administrator account, indicating token theft and reuse.
• Application: Unexpected administrative actions (configuration changes, user management, crontab modifications) performed shortly after a low-privileged user accessed the cache view endpoint (GitHub PoC).

No vendor patch is currently available; the MineAdmin vendor did not respond to the researcher's disclosure. As interim mitigations, administrators should implement strict permission identifiers on the /system/cache/view endpoint to enforce role-based access control, ensuring only authorized administrator roles can access cache data. Additional recommended steps include: restricting network access to MineAdmin instances to trusted IP ranges only; monitoring and alerting on access to the /system/cache/view endpoint by non-admin accounts; rotating all JWT tokens and Redis cache secrets if exploitation is suspected; and disabling the View Interface functionality if it is not operationally required. Upgrade to a patched version of MineAdmin as soon as one becomes available (GitHub PoC, Red Hat CVE).

The vulnerability was reported by researcher SourByte05 via a GitHub issue with a detailed proof-of-concept, noting that the vendor did not respond to early disclosure attempts. Red Hat tracked the CVE in their security advisory database. The vulnerability received coverage from automated CVE tracking services including VulDB, CVEFeed, and Vulners shortly after publication. No significant public commentary from major security researchers or media outlets beyond standard CVE aggregation has been identified (GitHub PoC, Red Hat CVE).
