CVE-2026-75800 – Authentication Bypass / Unauthenticated Account Takeover – Frontegg SAML SSO WordPr

Be the first to know when new zero-days emerge:

Summary

CVE-2026-75800 is a critical improper authentication vulnerability in the Frontegg SAML SSO plugin for WordPress, versions up to and including 1.0.1. The plugin fails to verify the cryptographic signature or issuer of incoming SAML authentication responses before establishing a user session, allowing a remote, unauthenticated attacker to forge SAML assertions and log in as any existing user — including administrators — or create arbitrary new accounts. The flaw carries a CVSS v3.1 base score of 9.8 (Critical).

Technical details

  • Root cause: The plugin’s SAML response handler does not validate the digital signature or the issuer identifier of SAML assertions received from an identity provider (IdP) before trusting the assertion and establishing a WordPress session.
  • Trigger conditions: An attacker submits a crafted/forged SAML response to the site’s SAML assertion consumer endpoint; because signature and issuer checks are skipped, the forged assertion is accepted as valid.
  • Attack vector: Network-based, requires no authentication and no user interaction (AV:N, PR:N, UI:N).
  • Impact: Full authentication bypass and account takeover — an attacker can impersonate any user, including site administrators, and the plugin’s auto-provisioning behavior (creating a new WordPress account from the email address in the SAML assertion) allows attackers to mint arbitrary accounts, including admin-level ones, resulting in complete loss of confidentiality, integrity, and availability of the affected WordPress site.
  • CWE classification: CWE-287 (Improper Authentication).

Affected software

  • Frontegg SAML SSO WordPress plugin: all versions up to and including 1.0.1

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: No fixed version of the plugin has been released; as of this writing the plugin has been closed/removed from the WordPress.org plugin repository pending review, and no updated release addressing this issue is available.
  • If no patch is available:
    • Disable and deactivate the Frontegg SAML SSO plugin immediately and revert to native WordPress authentication (or another vetted SSO/SAML solution) until a fixed version is released.
    • Audit existing WordPress user accounts, especially administrator accounts, for any unrecognized or recently created users that may indicate prior exploitation.
    • Restrict or block external access to the plugin’s SAML assertion consumer service (ACS) endpoint at the network/WAF layer until the plugin is patched or removed.
    • Monitor authentication logs for anomalous SAML login events or unexpected account creation 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.
