Exploitation Status
No confirmed exploitation observed yet
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

Description
A vulnerability was detected in ag-ui-protocol ag-ui 1.0. This impacts an unknown function of the file crates/ag-ui-client/src/sse.rs of the component SSE Frame Parser. Performing a manipulation results in resource consumption. The attack is possible to be carried out remotely. The pull request to fix this issue awaits acceptance.
Affected Products

Vendor / applianceDetect
Inventory every ag-ui-protocol ag-ui deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for exploitation at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.
Remediation status
No patch has shipped for CVE-2026-92362 yet — track the ag-ui-protocol ag-ui advisory for a fixed release and apply the workarounds below in the meantime.
Mitigate without a patch
Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.
How O3 protects you
O3 detects and blocks CVE-2026-92362 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.
Tailored to CVE-2026-92362. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
