The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up.

Exploitation Conditions

The concrete prerequisite named in the CVE is abuse of the GAPTEQ 'Company Manager' role, so realistic exploitation requires the attacker to hold or acquire a Company Manager account on a GAPTEQ Designer v3.5 instance and to have network reach to its web interface. This role requirement is the primary limiting factor - despite the published PR:N (unauthenticated) metric, the description implies an authenticated, role-scoped starting point rather than anonymous access, which meaningfully narrows the exploit population to environments where lower-tier delegated admins are not fully trusted.

Impact

The signals conflict and should be weighed carefully. The published CVSS 9.8 vector (AV:N/AC:L/PR:N/UI:N) implies fully unauthenticated network exploitation, yet the description ties the flaw to abuse of the 'Company Manager role,' which strongly implies the attacker must already hold that authenticated role - meaning PR:N is likely optimistic and the true privilege requirement is PR:L; verify with the vendor. SSVC raises priority (Exploitation: PoC, Automatable: yes, Technical Impact: total) and a public PoC repository exists, but the low EPSS (0.21%) and absence from CISA KEV indicate no confirmed widespread active exploitation to date. Because a working PoC is public and the impact is total, the practical takeaway is that even a mid-sized municipal IT team in olsztyn should treat a reachable GAPTEQ Designer instance as an urgent internal-hardening priority, while recognizing that real-world risk is bounded by the platform's limited deployment footprint and the probable need for an existing Company Manager account. Net: a genuine high-priority issue for organizations running GAPTEQ, but likely role-gated rather than a fully anonymous internet-wide threat.

Exploit ScenarioDerived

An attacker who obtains or is granted a 'Company Manager' role account in a GAPTEQ Designer 3.5 instance manipulates the role's functionality to escalate to higher (e.g., global administrative) privileges, gaining full control over the application's data and configuration. Because a public PoC exists and the CVSS complexity is low (AC:L), the technique is repeatable and, per SSVC, automatable once access to the role is available.

AnalysisAIv1 – Aug 18, 2026

Privilege escalation in GAPTEQ Designer v3.5 allows a remote attacker to abuse the Company Manager role to gain elevated privileges, per CWE-269 (improper privilege management). Publicly available exploit code exists (referenced on GitHub), and CISA's SSVC framework rates the technical impact as total and the flaw as automatable, though it is not listed in CISA KEV and EPSS remains low (0.21%, 11th percentile). The scope of affected deployments is limited to the GAPTEQ low-code application platform rather than a widely embedded library.

RemediationAI

No vendor-released patch identified at time of analysis; the references point only to the vendor homepage (https://gapteq.com/en/), the NVD record (https://nvd.nist.gov/vuln/detail/CVE-2026-50774), and researcher PoC material (https://github.com/Henkel-CyberVM/CVEs/tree/main/CVE-2026-50774), none of which cite a fixed build. Contact GAPTEQ directly to obtain a patched release beyond v3.5 and monitor the vendor site for an advisory. As compensating controls, restrict and audit assignment of the Company Manager role to the minimum set of trusted operators (reducing who can trigger the escalation), place GAPTEQ Designer behind network segmentation or a VPN/allowlist so the management interface is not broadly reachable (trade-off: added access friction for legitimate admins), enable and review authentication and role-change logging to detect abuse, and treat every existing Company Manager account as potentially able to reach full-privilege operations until patched.

Technical ContextAI · show details

GAPTEQ is a commercial low-code/no-code business application platform used to build database-driven web forms and enterprise apps; the Designer component is its authoring/administration environment. The vulnerability is classified as CWE-269 (Improper Privilege Management), meaning the application does not correctly enforce the boundary between what a given role may do and what it should be restricted from doing. Specifically, the 'Company Manager' role - a delegated administrative role intended to manage a company/tenant scope - can be leveraged to obtain privileges beyond its intended authorization level. The provided CPE string (cpe:2.3:a:n/a:n/a:*) is a placeholder with no real vendor/product tokens, so exact affected-configuration matching cannot be derived from NVD CPE data and must rely on the vendor's own versioning (v3.5).

DescriptionCVE.org

An issue in GAPTEQ Designer v.3.5 allows a remote attacker to escalate privileges via the Company Manger role.

Executive ViewAI

Why It Matters

GAPTEQ Designer v3.5 contains a critical remote privilege escalation vulnerability (CVE-2026-50774) enabling attackers to gain complete administrative access through Company Manager role manipulation. Organizations deploying this low-code platform face total system compromise and must immediately implement containment measures, as vendor patches are not available. A complete inventory of GAPTEQ usage is required to assess and mitigate business exposure.

Business Impact: High
Compensating Controls

No vendor-released patch identified at time of analysis. Interim mitigations include: implement network segmentation to isolate GAPTEQ instances and restrict administrative access; disable Company Manager role entirely if operationally feasible, or restrict its use to critical functions only; enable detailed audit logging of all privilege-related activities; deploy intrusion detection rules to flag Company Manager abuse patterns; and consider air-gapping critical GAPTEQ deployments until vendor patches are released.
