M-26-05 Rescinded prior federal software security memorandums for On Jan. 23 2026
Public Sector Action
Summary

Show ▼
OMB issued M-26-05 on Jan. 23, 2026, rescinding prior federal software security memorandums and removing the expectation that agencies require SBOMs and software self-attestations. The change affects federal procurement and shifts assurance decisions back toward agency-specific judgment, even though agencies may still choose to request the artifacts. It matters because the rollback could weaken baseline visibility into software supply-chain risk and create more inconsistent requirements for vendors.

OMB M-26-05 rescinds SBOM and attestation mandates
Legal Policy Action UpdateOMB Director Russell Vought issues M-26-05 and rescinds M-22-18 and M-23-16, ending the federal mandate for software bills of material (SBOMs) and self-attestations tied to NIST secure development guidance. Federal agencies may still choose to require SBOMs and letters of attestation, but the previous requirement and expectation to collect them are withdrawn.

Security leaders debate the rollback's impact
Initial DisclosureSecurity leaders debate whether removing the SBOM and attestation requirements will improve agency flexibility or weaken software supply-chain security. Some argue that procurement should focus on mission risk and operational impact, while others warn that the change will reduce verification, encourage inconsistent vendor demands, and fragment the baseline around SSDF-aligned practices.
