Runtime: SAP's kernel has a CVSS 10-shaped hole in it. Buckle up.

+ OpenAI’s “observability” headaches, and more. 

A critical vulnerability (CVSS 10) in SAP’s kernel code – now allocated CVE-2026-44756 – is probably the worst Onapsis CTO Juan Perez-Etchegoyen has seen, he told Runtime/The Stack today. Almost every enterprise SAP software product is affected by the pre-auth RCE bug.

The bug can be exploited “from the Internet-facing web layer, from the SAP GUI layer every end user connects to, and from the RFC layer that links SAP systems to one another” he said. There are, conservatively, 10,000+ instances publicly exposed, let alone those on private networks.

Patching requires downtime and SAP customers are not the fastest to move. This time, if they want to avoid a world of pain, they need to be.

SAP has a patch out today. SAP security specialist Onapsis – which is calling the bug “OVERPASS” – urges emergency patching and expects patch-diffs to lead to a public POC and exploitation in short order.

With SAP NetWeaver vulnerability CVE-2025-31324 2025’s most exploited vulnerability, according to Mandiant’s M-Trends 2026 report, users should pay heed and patch up fast. More details below.

Through a glass, darkly?

OpenAI’s latest full-fat frontier model is now rolling out to enterprise users. Not everyone is wildly excited about it, even if OpenAI is now referring to “alien intelligence.” As The Stack’s Kiera Fields notes, OAI’s concerns about the noticeably reduced “monitorability” of its chain-of-thought reasoning may also cause CTOs in heavily regulated industries concern. 

“That’s just a harness/separate toolchain problem” quoth you?

Well, maybe, it’s early days, but we flagged it below regardless.

SolarWinds has a new CISO. He's not bothered by the history. He's moisturised, happy, in his lane. We sat down to chat with him and SolarWinds CTO Krishna Sai about how to strike that age-old balance of security and innovation when everyone is chuntering away about new agentic features. (An interesting digression we briefly went down was around AI gateways. SolarWinds, like Bloomberg, opted to build its own. The Kongs and Solos of this world clearly have some work to do... )
