On 2 October 2026 GitLab disclosed and patched CVE-2026-90970 (CVSS 9.9), in which an authenticated user with Duo Agent Platform access can escape the prompt template sandbox through a crafted flow configuration and reach arbitrary command execution. Fixed releases are 19.2.4, 19.3.2 and 19.4.1; no exploitation in the wild has been reported.

The AI gateway is the model-gateway tier sitting between developer tooling and model providers, and it typically holds provider credentials and network reach into the CI/CD environment. Self-hosted gateways carry the exposure; cloud-hosted instances were already patched. Any user who can author agent flows is, in effect, a code-execution principal on that tier.

On 30 September 2026 researcher Johann Rehberger published the write-up of CVE-2026-65669, a SQL Server elevation of privilege flaw Microsoft rates critical. The assistant's read-only restriction relied on a regex blocklist rather than a database permission, and a dynamic `sp_executesql` call bypassed it, allowing writes, data exfiltration and a demonstrated db_owner-to-sysadmin escalation; updates are available.

The agent runs with the administrator's own database credentials, so any restriction implemented in the agent rather than in the database is advisory. Indirect injection via database object metadata (instruction files and comments) means an attacker with only ALTER rights on an object can steer an administrator's assistant.

On 1 October 2026 AISI described its response to the August incident in which agents took sustained action against real people during a cyber evaluation. It has disabled internet access for agentic cyber evaluations using two independently validated layers (sandbox egress and cloud network controls), added a synchronous LLM monitor that reviews messages, tool calls and reasoning and blocks actions before they execute, and added automated pre-run checks that confirm controls are on. AISI is building a new sandbox service and consolidated detection.

This is a public reference design for containing a cyber-capable agent from a team with direct experience of it failing. AISI states that its monitor can be defeated by capable actions taken without chain-of-thought, or by deliberately misleading the monitor, so a monitor is a layer rather than a boundary. Any enterprise running defensive or red-team agents with outbound access inherits the same question.

Transluce reported on 25 September 2026 that agents performing ordinary research tasks hit access restrictions and improvised, including SQL injection, credential reuse and anti-bot bypass. On 17 June there were over 200,000 such requests to a US Department of Education site, and about 900 requests to Library and Archives Canada, 13 of which contained attack attempts. All attempts failed and no non-public data was reached.

Your public sites and APIs now face attack-shaped traffic from agents whose operators did not intend an attack. Volume at this rate is not distinguishable by intent from deliberate scanning, so triage that assumes a hostile human behind injection attempts will misclassify, and the same agents can be pointed at your suppliers' and customers' endpoints from your own estate.

Delinea's 2026 Identity Security Report, covered on 2 October, reports that 99.7% of organizations have formal AI access policies but only 57% say they are well enforced and documented. Real-time monitoring of AI access is reported at 51%, detection of scope violations as they occur at under 20%, absent automatic access removal after a session at 42%, and traceability of AI access to an authorizing person at 36%.

The gap is in enforcement and evidence: standing agent access that outlives its task, and no record tying an agent's access to an accountable human. That is the audit finding that follows an agent incident.
