SAP patch day trust failures: what IAM teams need to know

TL;DR: SAP’s February 2026 Patch Day includes 26 security notes, with two Critical issues in CRM scripting and RFC authorization enforcement, plus high-risk defects in BusinessObjects and XML signature handling, according to Pathlock. The pattern is clear: trusted SAP execution paths are still where access control, identity trust, and availability break first.

NHIMG editorial — based on content published by Pathlock: SAP’s February 2026 Patch Day analysis

By the numbers:

• SAP’s February 2026 Patch Day includes 26 SAP Security Notes, with 2 Critical and 6 High severity issues.

Questions worth separating out

Q: What breaks when SAP authorisation checks fail in RFC paths?

A: When RFC checks fail, a low-privileged authenticated user can trigger remote-enabled operations that were meant to be blocked.

Q: When should SAP teams prioritise trust-boundary fixes over other patch work?

A: Prioritise trust-boundary fixes when a flaw can alter identity, invoke backend functions, or break shared availability across systems.

Q: What do security teams get wrong about signed XML in enterprise SSO?

A: They often assume that a valid signature means the whole message is safe.

Practitioner guidance

• Tighten SAP CRM scripting access immediately Disable the legacy Scripting Editor service if it is not operationally required, and reduce access to CRM scripting-related functionality to a minimal admin set.
• Revalidate RFC trust and S_RFC assignments After applying the kernel fix, inspect trusted RFC destinations, background RFC usage, and permissive S_RFC roles for cross-system reachability that exceeds business need.
• Test signed XML consumption, not just signature acceptance Review ABAP web services and SAML-connected flows to confirm the application consumes the same XML element that was signed.
