Vulnerability Details: CVE-2026-41005

What is CVE-2026-41005 and which systems are affected?

CVE-2026-41005 is a critical SAML authentication bypass vulnerability in Cloud Foundry UAA (User Account and Authentication) versions 2.0.0 through 78.13.0 and all Cloud Foundry CF Deployment versions through v56.1.0. The flaw allows unauthenticated attackers to impersonate arbitrary users by submitting forged SAML assertions, potentially gaining full access to all UAA-protected systems. Source: NIST CVE-2026-41005, June 11, 2026. Note: Only these specific versions are affected; later versions address the vulnerability.

What is the root cause of the CVE-2026-41005 vulnerability?

The root cause is that Cloud Foundry UAA incorrectly treated XML encryption as a substitute for XML signatures. When UAA received a SAML assertion that was encrypted but unsigned, it accepted the assertion as authentic, conflating decryption with proof of origin. This allowed attackers to submit encrypted but unsigned assertions, bypassing authentication. Note: This issue is specific to the affected UAA versions and SAML flows. Source: Cloud Foundry Security Advisory.

What is the severity and impact of CVE-2026-41005?

CVE-2026-41005 has a CVSS v3.1 base score of 9.0 (Critical). The vulnerability enables complete authentication bypass, allowing attackers to obtain OAuth 2.0 access tokens for any user and impersonate them across all UAA-protected systems. The impact metrics are Confidentiality: High, Integrity: High, Availability: High, with Scope: Changed. Note: The compromise can extend beyond UAA to all downstream services using UAA-issued tokens. Source: NIST CVE-2026-41005.

How can organizations mitigate or remediate CVE-2026-41005?

Immediate mitigation requires upgrading uaa_release to v78.15.0 or later (v78.14.0 should be avoided due to known issues) and CF Deployment to v57.0.0 or later. If immediate patching is not feasible, set wantAssertionSigned=true on all SAML Service Provider configurations, disable or restrict SAML2 bearer grant clients at the token endpoint, and apply network-layer controls to limit access to UAA SAML endpoints. Note: These mitigations reduce but do not eliminate risk until patching is complete. Source: Cloud Foundry Security Advisory.

CVE-2026-41005 – Authentication Bypass – Cloud Foundry UAA 2.0.0 through 78.13.0

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

Summary

CVE-2026-41005 is a critical SAML authentication bypass vulnerability in Cloud Foundry UAA (User Account and Authentication), classified CWE-347 (Improper Verification of Cryptographic Signature) with a CVSS 3.1 score of 9.0 (Critical). The flaw allows any unauthenticated attacker with network access to impersonate arbitrary users by crafting forged SAML assertions, potentially gaining full access to all UAA-protected systems. All UAA releases from v2.0.0 through v78.13.0 and all CF Deployment versions through v56.1.0 are affected.

Technical details

  • Root cause: Cloud Foundry UAA incorrectly treated XML encryption (a confidentiality control) as a substitute for XML signatures (an authenticity/integrity control). When UAA received a SAML assertion that was encrypted but unsigned, it accepted the assertion as authentic — conflating the ability to decrypt ciphertext with proof that a trusted Identity Provider (IdP) issued the message.
  • Why encryption is insufficient for authenticity: Encryption of SAML assertions uses the Service Provider’s (SP) public key, which is published in the SP’s metadata and freely accessible to any party on the internet. Any actor — not only a trusted IdP — can therefore produce ciphertext that UAA will decrypt. Successful decryption proves nothing about the origin of the message.
  • Affected SAML flows: Two flows are vulnerable: (1) the OAuth 2.0 SAML2 bearer grant (token endpoint), and (2) browser SSO via the Assertion Consumer Service (ACS) when wantAssertionSigned is set to false.
  • Attack vector: The SAML token endpoint and ACS are HTTP/HTTPS endpoints exposed to the network. An attacker submits a crafted SAML assertion — encrypted with the publicly available SP public key but carrying no valid IdP signature — directly to these endpoints.
  • No authentication required: The attacker requires no prior credentials or session; the SP public key needed to construct the forged ciphertext is retrieved from published UAA metadata.
  • Impact: Complete authentication bypass — the attacker can obtain OAuth 2.0 access tokens for any user in the system, resulting in full identity impersonation. CVSS impact metrics are Confidentiality:High, Integrity:High, Availability:High with Scope:Changed, reflecting that the compromise extends beyond UAA itself to all downstream services protected by UAA-issued tokens.

Affected software

  • Cloud Foundry UAA (uaa_release): v2.0.0 through v78.13.0 (inclusive)
  • Cloud Foundry CF Deployment: all versions through v56.1.0 (inclusive)

Severity

  • CVSS v3.1 Base Score: 9.0 (Critical)
  • Vector String: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate — upgrade:
    • Upgrade uaa_release to v78.15.0 or later (note: v78.14.0 contains known issues and should not be used as the target version).
    • Upgrade CF Deployment to v57.0.0 or later, which bundles uaa_release v78.16.0.
  • If immediate patching is not feasible:
    • For browser SSO flows, set wantAssertionSigned=true on all SAML Service Provider configurations to require IdP signatures on assertions; this removes the ACS attack surface.
    • Disable or restrict access to SAML2 bearer grant clients at the token endpoint where not operationally required.
    • Apply network-layer controls to limit access to UAA SAML endpoints to known, trusted IdP source IP ranges.

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.
