Chapter 06

State Sync Poisoning in AI Agents

State sync poisoning happens when shared state, synchronized context, or cross-system memory carries unsafe assumptions into later decisions that the receiving agent did not independently verify.

What it is

This chapter covers the family where the dangerous content is not only a prompt or a file, but a synchronized state artifact. Shared boards, replicated context, cached state, orchestration memory, and workflow checkpoints can all move assumptions from one component to another. Once those artifacts are treated as canonical, an attacker can poison a whole chain through the sync layer.

Why it matters for agents

This matters because agents increasingly inherit context they did not create. A poisoned status board, cached summary, or synchronization artifact can look more trustworthy than the original evidence because it appears structured, current, or operationally central. That makes state sync a high-leverage attack surface in multi-agent and long-running systems.

How it shows up in workflows

Common shapes include poisoned shared memory, stale-but-authoritative sync files, desynchronized control planes, cross-agent contamination, and workflows where one component updates state while another component acts on it without re-verification. These failures are especially dangerous when the synced object also affects routing, approvals, or downstream execution policy.

What Sunglasses sees

Synchronized context is still untrusted input until the receiving workflow re-establishes provenance and freshness.

GLS-CAI-239 Cross-agent injection — trusted handoff override HIGH
cross_agent_injection tool_output, message
Detects cross-agent injection attacks where output from an upstream, previous, delegated, planner, or worker agent is presented as trusted, authoritative, verified, signed, or approved — and that claim is used to justify ignoring, bypassing, overriding, disregarding, or replacing the downstream agent's system prompt, policy, guardrails, safety checks, or instructions. Covers A2A (agent-to-agent) trust-boundary abuse in multi-agent workflows.

GLS-CAI-711 OCR Alt-Text Cross-Modal Instruction Smuggle HIGH
cross_agent_injection message, file, tool_output, log_memory
Attacker hides instructions inside text extracted from another modality (image OCR, subtitle, audio transcript, PDF footnote) and the agent silently promotes that untrusted span into tool arguments or policy context, bypassing channel trust boundaries.

GLS-CAI-712 Transcript Channel Desync Sidecar Authority Pivot HIGH
cross_agent_injection message, file, tool_output, log_memory
Attacker hides tool-driving directives in an auxiliary modality channel (sidecar metadata, OCR raw tokens, alt-text, late-arriving audio segments) so the reviewed transcript passes safety checks while the executor reads a different, malicious representation.

GLS-CAI-713 Cross-Modal Evidence Swap OCR Override HIGH
cross_agent_injection message, file, tool_output, log_memory
Attacker plants conflicting claims across modalities (benign text plus malicious OCR or caption) so the orchestrator promotes the wrong channel as authoritative and a shallow merge silently flips guardrail fields, granting tool execution that policy should deny.

GLS-CAI-626 Cross-Feed Metric Bleed Fake Consensus Bypass HIGH
cross_agent_injection message, file, tool_output, log_memory
Attacker reframes Ops telemetry (scanner, bot noise) as Growth truth (or vice versa) and fabricates cross-source consensus, so AI-assisted reporting agents corrupt priorities and either invent demand or downgrade real abuse.

GLS-CAI-714 Agent Authority Leak Checkpoint Token Spoof CRITICAL
cross_agent_injection message, file, tool_output, log_memory
Attacker crafts handoff text that smuggles authority forward between agents (claimed prior approvals, spoofed checkpoint tokens, laundered summary bullets) so a downstream role executes unverified instructions as if upstream policy had signed them.

GLS-CAI-715 Cross-Modal Bridge Abuse OCR Metadata Smuggle HIGH
cross_agent_injection message, file, tool_output, log_memory
Attacker exploits the trust shift across modality bridges (OCR, document metadata, retrieval snippets, tool error reflections) so parser-supplied content gains de facto instruction authority and steers downstream tool calls without crossing a real policy gate.
