Summary

CVE-2026-28185 is a critical unauthenticated broken authentication vulnerability in the "Log in with Google" WordPress plugin developed by rtCamp. The flaw stems from insufficient verification of data authenticity (CWE-345) in the plugin’s authentication flow, allowing attackers to bypass login controls without valid credentials. It carries a CVSS v3.1 base score of 9.8 (Critical) and affects all versions up to and including 1.4.2.

Technical details

  • Root cause: insufficient verification of data authenticity (CWE-345) within the plugin’s Google-based login/authentication handling.
  • Classified under CAPEC-115 (Authentication Bypass) and OWASP A7: Identification and Authentication Failures.
  • Attack vector: network-based, low attack complexity, no privileges and no user interaction required to exploit.
  • Impact: full compromise of confidentiality, integrity, and availability, consistent with the ability to bypass authentication controls on affected WordPress sites.
  • CISA’s vulnerability enrichment records the technical impact as "total" and the flaw as automatable.

Affected software

  • Plugin: Log in with Google (WordPress plugin, package login-with-google), developed by rtCamp
  • Affected versions: all versions up to and including 1.4.2
  • Fixed version: 1.4.3 and later

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: Update the "Log in with Google" WordPress plugin to version 1.4.3 or later.
  • If immediate patching is not possible, restrict or disable the plugin’s login functionality until the update can be applied, and monitor authentication logs for anomalous login activity.

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.
