Summary

CVE-2026-84148 is an Insecure Direct Object Reference (IDOR) vulnerability affecting the Manacle Technologies Multi-tenant ERP System. Flawed authorization controls in an API endpoint allow an unauthenticated attacker to manipulate request parameters and access sensitive information belonging to other tenants/users. The flaw has been rated CRITICAL, with a CVSS v4.0 base score of 9.2.

Technical details

  • Root cause: Improper authentication and authorization checks on an API endpoint, allowing user-controlled identifiers/keys to be used to reference objects belonging to other users (CWE-639: Authorization Bypass Through User-Controlled Key).
  • Trigger conditions: An attacker sends crafted requests to the vulnerable API endpoint, manipulating object reference parameters (e.g., record/user identifiers) without needing valid credentials.
  • Attack vector: Network-based, requires no privileges and no user interaction (AV:N/AC:L/AT:N/PR:N/UI:N).
  • Impact: Exposure of sensitive information belonging to other users/tenants on the affected system, which is especially severe in a multi-tenant ERP environment since it could allow cross-tenant data leakage.

Affected software

  • Manacle Technologies Multi-tenant ERP System (specific affected version(s) not disclosed by the vendor or in the public advisory)

Severity

  • CVSS v4.0 Base Score: 9.2 (Critical)
  • Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:H/SI:N/SA:N
  • Note: This vulnerability was disclosed alongside two related issues in the same product — an unauthenticated file-upload Remote Code Execution flaw (CVE-2026-84147) and an exposed .git directory information disclosure issue (CVE-2026-84149) — per the CERT-In advisory (CIVN-2026-0430).

Mitigation and recommended actions

  • Immediate: No specific patched version has been published in the public advisory. Organizations running Manacle Technologies’ Multi-tenant ERP System should contact the vendor directly to obtain a patched version or hotfix addressing CVE-2026-84148.
  • If no patch is available:
    • Restrict network access to the ERP application’s API endpoints to trusted/internal networks only, and place it behind a properly configured WAF or reverse proxy.
    • Audit API endpoints for object-reference parameters and enforce server-side authorization checks that verify the requesting user/tenant owns the referenced resource.
    • Monitor logs for anomalous or sequential parameter enumeration against API endpoints, which may indicate exploitation attempts.
    • Given this issue was disclosed alongside a related RCE (CVE-2026-84147) and an exposed .git directory issue (CVE-2026-84149) in the same product, review the deployment for exposed .git directories and unauthenticated file-upload functionality as well.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
