AWS Kiro: Arbitrary Code Execution via Indirect Prompt Injection
Researchers found a vulnerability (CVE-2026-10591) in AWS Kiro, an agentic IDE, where hidden instructions planted in a web page or source file that Kiro processes can trigger indirect prompt injection to rewrite Kiro's own MCP server configuration (~/.kiro/settings/mcp.json) or allowlist arbitrary Bash commands in .vscode/settings.json, achieving arbitrary code execution on the developer's machine with no approval prompt. The human-in-the-loop approval boundary is bypassed because Kiro can write to these config files without user consent, and AWS has issued a fix and CVE.indirect-prompt-injection · prompt-injection · remote-code-execution · tool-abuse · config-poisoning

Agentjacking exposes a broken trust model in AI coding agents
"Agentjacking," documented by Swarmnetics and Tenet Security, abuses the trust AI coding agents place in external error-report telemetry: an attacker who obtains a publicly exposed Sentry DSN can inject malicious instructions into error reports that the agent treats as actionable, enabling theft of cloud keys, Git credentials, and private repo URLs. The core flaw is that systems built to process trusted telemetry conflate source trust with action trust in MCP-connected agent workflows.

We put the exploit in a picture. Your AI code reviewer never opens it.
Researchers from the University of Missouri-Kansas City's ASSET Research Group demonstrated 'Ghostcommit,' an attack that hides malicious prompt-injection instructions inside a PNG image so AI code reviewers (CodeRabbit, Cursor Bugbot) never see them. A benign-looking AGENTS.md convention file points to build-spec.png, whose rendered text instructs a coding agent to read the repo's .env byte-by-byte and emit the secrets as an integer tuple; the payload sits dormant until an unrelated agent session triggers exfiltration. A proof-of-concept is published on GitHub and the findings were disclosed to affected vendors. Details →First reported · updated · 2 reports adversa.ai
GuardFall: a universal shell injection vulnerability in open-source AI agents
GuardFall, disclosed by Adversa AI, is a universal shell injection vulnerability affecting open-source AI coding agents, where decades-old shell injection techniques bypass the agents' modern command-filtering safeguards. Because these agents run shell commands with the operator's full account authority, the flaw enables command execution across a surveyed cohort of 11 popular open-source agents.
