Summary

CVE-2026-28165 is a critical unauthenticated privilege escalation vulnerability in the Digits WordPress plugin (developed by UnitedOver, LLC), affecting all versions up to and including 9.2. The flaw stems from incorrect privilege assignment (CWE-266) and allows an unauthenticated attacker to gain elevated privileges on the affected WordPress site over the network, with no user interaction required. The issue carries a CVSS v3.1 base score of 9.8 (Critical).

Technical details

  • Root cause: Incorrect privilege assignment (CWE-266) within the Digits plugin’s authentication/login handling logic.
  • Trigger conditions: No authentication or user interaction is required to exploit the flaw; the vulnerable functionality is reachable by any unauthenticated visitor to a WordPress site running the affected plugin version.
  • Attack vector: Network — the vulnerability is exploitable remotely over HTTP/HTTPS against the plugin’s exposed endpoints.
  • Impact: Full compromise of confidentiality, integrity, and availability is possible, consistent with an attacker escalating to a privileged account (e.g., administrator) on the WordPress site without credentials.

Affected software

  • Digits WordPress plugin (by UnitedOver, LLC) — versions 9.2 and earlier

Severity

  • CVSS v3.1 Base Score: 9.8 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate: Upgrade the Digits plugin to a version newer than 9.2 as soon as the vendor (UnitedOver, LLC) releases a fixed build. At the time of this writing, no publicly confirmed patched version number has been identified — check the vendor’s official changelog/update channel for the fix before relying on version alone.
  • If no patch is confirmed available: Disable or remove the Digits plugin from any internet-facing WordPress installation until a vendor fix is confirmed and applied. Restrict or monitor access to the plugin’s login/registration endpoints, and review WordPress user accounts for unexpected administrator-level accounts as an indicator of compromise.

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.
