Summary

CVE-2026-57700 is a critical Unrestricted Upload of File with Dangerous Type vulnerability (CWE-434) in OMGF Pro, a premium WordPress plugin by Daan.Dev that enables GDPR-compliant local hosting of Google Fonts. The flaw affects all versions of OMGF Pro through 5.2.6 and carries a maximum CVSS 3.1 base score of 10.0 (Critical), reflecting unauthenticated remote exploitability with complete impact across confidentiality, integrity, and availability. A patched release (version 5.2.7) was published by the vendor on June 25, 2026.

Technical details

  • Root cause: The plugin fails to validate or restrict the type of files that can be uploaded, permitting submission of arbitrary file types — including server-executable files such as PHP webshells — through unauthenticated HTTP requests.
  • Trigger conditions: No authentication, elevated privileges, or user interaction is required. The vulnerability is directly exploitable over the network with low attack complexity (AC:L).
  • Attack vector: Remote, unauthenticated HTTP/HTTPS request targeting the plugin’s file upload functionality.
  • Impact: Successful exploitation enables an attacker to upload and execute malicious files on the target server. The CVSS Scope is rated "Changed" (S:C), indicating that a successful attack can affect resources beyond the vulnerable component itself, with complete confidentiality (C:H), integrity (I:H), and availability (A:H) impact — consistent with full server compromise.

Affected software

  • OMGF Pro (Optimize My Google Fonts Pro, by Daan.Dev) — all versions up to and including 5.2.6

Severity

  • CVSS v3.1 Base Score: 10.0 (Critical)
  • Vector string: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate: Update OMGF Pro to version 5.2.7 or later. The vendor released the patched version on June 25, 2026.
  • If immediate patching is not possible: Restrict access to the WordPress administration interface and plugin upload endpoints at the web server or network perimeter level. Consider temporarily deactivating the plugin until the update can be applied.

IONIX Status

The IONIX research team is tracking ongoing exploitation attempts and recommends immediate patching. Potentially affected assets are outlined in this post.

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.
