TL;DR: On June 9, 2026, SAP's monthly Security Patch Day shipped 15 new Security Notes - and one of them, Security Note #3746332, patches CVE-2026-44748, an XML Signature Wrapping flaw in SAP NetWeaver AS ABAP and ABAP Platform SAML authentication rated 9.9 on the CVSS scale. Per BleepingComputer's reporting, an authenticated normal-privilege attacker can forge a valid signed SAML message, modify the XML payload, and gain unauthorized access across trust boundaries. For NC manufacturers and mid-market firms running SAP, this is one of the most consequential patches of 2026.
Critical takeaway: SAP NetWeaver is the bedrock of SAP ECC and S/4HANA deployments. A SAML signature-wrapping bypass collapses identity federation as a defensive boundary - meaning the attacker can move laterally with forged identity across HR, finance, supply chain, and shop-floor modules. Patch within the week, rotate SAML signing keys, and hunt for anomalous SAML message structure.

What is CVE-2026-44748 in plain language?
CVE-2026-44748 is an XML Signature Wrapping vulnerability in SAP NetWeaver AS ABAP and ABAP Platform's SAML authentication path, rated 9.9 on the CVSS scale and patched in SAP Security Note #3746332. Per SecurityWeek's coverage and SocRadar's analysis, an authenticated attacker who possesses a valid signed SAML message can manipulate the XML structure of that message before it reaches the verifier. Because the verifier does not properly validate the cryptographic signature against the full XML document, it accepts the tampered identity claims as legitimate.
Three facts NC SAP customers must internalize:
- The flaw spans the entire ABAP install base. Per Cybersecurity News reporting, CVE-2026-44748 affects SAP_BASIS versions 702 through 919 - meaning virtually every supported NetWeaver release. Any NC SAP ECC, S/4HANA, or Solution Manager instance that uses SAML SSO is in scope.
- Federation is the attack surface. Per BleepingComputer, the attacker forges identity information across trust boundaries. That includes any external IdP federation NC manufacturers use to connect SAP to Microsoft Entra ID, Azure AD, Okta, ADFS, or Ping. Disabling SAML temporarily mitigates the exposure but breaks SSO.
- It is one of four critical SAP issues this month. Per ERP Today's June patch summary, SAP released four critical fixes in June 2026 covering NetWeaver, ABAP, and Commerce Cloud. A single patching campaign cannot stop at one CVE.
The practical question for an NC SMB SAP customer is "Has SAP NetWeaver federated authentication been the boundary we relied on?" If yes, that boundary just dissolved until Security Note #3746332 is applied and SAML signing keys are rotated.
Why does CVE-2026-44748 matter so much for NC manufacturers?
Because the NC manufacturing economy runs SAP. Per the North Carolina Department of Commerce, manufacturing represents roughly $109 billion of NC's gross state product and employs more than 478,000 North Carolinians - and many of the state's mid-to-large manufacturers run SAP ECC or S/4HANA as their system of record for finance, supply chain, HR, and production planning.
- SAP is the operational and financial nerve center. A SAML bypass in NetWeaver gives an attacker the ability to impersonate a finance manager, plant supervisor, or supply chain analyst. That maps directly to wire fraud (BEC inside SAP), inventory manipulation, and master data tampering.
- NC defense contractors with SAP have CMMC exposure. Per CMMC 2.0, if SAP touches CUI - including pricing, technical data, or contract-specific manufacturing instructions - the SAP perimeter is in CMMC scope. A 9.9 CVSS authentication bypass on that perimeter is a contractual reporting event if exploited.
- NC food, textile, and chemical manufacturers face FDA/OSHA/EPA audit exposure. Per NIST SP 800-171 Rev. 3, federally regulated NC manufacturers must protect controlled unclassified information across access control and audit boundaries - both of which SAML federation enforces.
Quotable definition: CVE-2026-44748 is a 9.9 CVSS XML Signature Wrapping vulnerability in SAP NetWeaver AS ABAP and ABAP Platform's SAML authentication, patched in SAP Security Note #3746332 on June 9, 2026. An authenticated normal-privilege attacker can modify the XML structure of a signed SAML message after signing, causing NetWeaver to accept forged identity claims across federation trust boundaries.
How can an NC manufacturer respond to CVE-2026-44748 this week?
A four-step kill chain: patch, rotate, harden, and hunt. Each step closes a different exposure window.
- Apply SAP Security Note #3746332 across all NetWeaver and ABAP Platform instances. Per SAP's Security Patch Day portal, the note covers SAP_BASIS 702-919. NC SAP teams should commit to a 7-day SLA for production and 72 hours for non-production, and stand-up validation testing against existing SAML integrations.
- Rotate SAML signing keys with every federated identity provider. Per OASIS SAML security guidance, assume that any pre-patch key material reachable from the compromised path is potentially under attacker control. Rotate SAP, IdP, and any service provider signing certificates and update metadata.
- Harden SAP perimeter and federation configuration. Per SAP's secure configuration guidance for NetWeaver, restrict SAML endpoints to known IdPs by certificate pinning where supported, enforce strict assertion expiration windows, and tighten audience restrictions.
- Hunt for anomalous SAML messages and unexpected privilege grants. Pull SAP Security Audit Log (SM20) data for unusual SAML processing, look for authentication events from non-typical IPs, and reconcile the user master with HR records to detect ghost or escalated accounts.
The defensive principle is straightforward: patch the bypass, retire the keys that the bypass could have leaked, and prove no attacker rode the window from disclosure to patch.
What does layered SAP defense cost an NC manufacturer?
For a typical NC mid-market manufacturer with SAP ECC or S/4HANA, 2-4 NetWeaver instances, and a federated IdP, layered defense is well inside the budget of a single regulated event.
| Control | Typical NC SAP customer monthly cost | What it addresses |
|---|---|---|
| Same-week SAP Patch Day deployment | Bundled with managed SAP/IT | Closes CVE-2026-44748 and the next critical CVE |
| SAML signing key rotation cadence | Bundled with managed cybersecurity | Limits blast radius of identity federation flaws |
| SAP audit log (SM20) monitoring | $500-$2,000/month | Detects anomalous authentication events |
| Managed EDR/MDR with 24/7 SOC | $8-$15 per endpoint | Detects post-bypass lateral movement |
| Web Application Firewall tuned for SAP | $500-$1,500/month | Blocks crafted SAML message payloads |
| Identity federation hardening (certificate pinning, audience restrictions) | Bundled with managed IT | Reduces attack surface beyond the patch |
| Incident response retainer | $500-$2,000/month | Activates 72-hour notification clock |
Per the Ponemon Institute's research on industrial breach economics, the average breach involving identity federation compromise runs $4.45 million for mid-market organizations. Layered SAP defense runs a small fraction of that and reduces the probability meaningfully.
Why is this an NC-specific concern?
Because NC's SAP install base sits inside three of the highest-target verticals - manufacturing, defense, and large-scale healthcare - and the NC notification and contractual regimes are unforgiving.
- NC manufacturers operate cross-state and federal contracts. Per the NC Manufacturing Extension Partnership, NC manufacturers regularly serve federal agencies, multi-state OEMs, and global supply chains. An SAP compromise rapidly becomes a supplier-network event with notification cascading across states and contract clauses.
- NC defense subcontractors have CMMC scope on SAP. Per CMMC 2.0, confirmed CUI compromise on an SAP boundary triggers prime-contractor notification clocks and DoD reporting.
- NC healthcare networks with SAP financials face HIPAA and state law overlap. Per the HHS HIPAA Security Rule, federated identity providing access to systems that touch PHI or HR/financials must meet access-control and audit standards a SAML bypass directly undermines.

Frequently Asked Questions
What exactly is CVE-2026-44748?
CVE-2026-44748 is a 9.9 CVSS XML Signature Wrapping vulnerability in SAP NetWeaver AS ABAP and ABAP Platform's SAML authentication. Per SocRadar's analysis and SAP Security Note #3746332, an authenticated attacker can modify a signed SAML message's XML structure after signing, causing NetWeaver to accept tampered identity claims across trust boundaries.
Which SAP versions are affected?
Per Cybersecurity News, SAP_BASIS versions 702 through 919 are affected - effectively the entire supported NetWeaver install base. NC SAP customers running ECC, S/4HANA, or Solution Manager with SAML SSO are exposed until Security Note #3746332 is applied.
Has CVE-2026-44748 been exploited in the wild?
As of June 12, 2026, there is no public report of in-the-wild exploitation. However, per SecurityWeek, 9.9 CVSS authentication bypass flaws with public disclosure typically see weaponization within days. NC SAP teams should treat this as a same-week patch SLA.
Can NC manufacturers disable SAML temporarily as a workaround?
Yes - per SocRadar's coverage, disabling SAML authentication temporarily mitigates the vulnerability. However, it breaks single sign-on and is unsuitable for most production environments. Patch and rotate is the operational path.
Do NC defense contractors need to report CVE-2026-44748 exposure?
If SAP NetWeaver touches CUI and an audit shows no patch and no compensating control, that posture itself is a CMMC compliance gap. A confirmed exploitation on an in-scope boundary is a contractual reporting event under prime-contractor flow-downs and CMMC 2.0 reporting requirements.
Does Preferred Data support NC SAP customers?
Yes. Preferred Data Corporation supports NC manufacturers and regulated mid-market organizations with managed cybersecurity, managed IT, ERP integration, and incident response. Our 200-mile on-site footprint covers the major NC SAP customer base. Call (336) 886-3282 for an emergency posture review.
What is the most important single control to add this week?
SAP Security Audit Log (SM20) monitoring connected to a 24/7 managed SOC. Most NC SAP customers have audit logging enabled but do not have human eyes on the data. CVE-2026-44748 is exactly the kind of post-exploitation activity SM20 telemetry can surface in time to matter.
