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

CVE-2026-49468 - Red Hat Customer Portal
CVE-2026-49468 is an Important-severity (CVSS 8.1) authentication-bypass flaw in LiteLLM, a proxy server (AI Gateway) used to call LLM APIs. A remote attacker sending a crafted Host header can bypass the proxy authentication layer to gain unauthenticated access to protected management routes, potentially leading to full system compromise. The issue is fixed in LiteLLM v1.84.0 (GHSA-4xpc-pv4p-pm3w), and Red Hat notes its default images do not start the vulnerable proxy. Details →First reported redhat.com
CVE-2026-12112 - Red Hat Customer Portal
CVE-2026-12112 is a session management flaw in the foreman-mcp-server (MCP Server) shipped with Red Hat Satellite 6.18 and 6.19, where unauthenticated attackers can hijack active administrative sessions because the server caches authenticated client connections and trusts a non-secret session ID without re-validating authentication tokens, while also logging newly created session IDs to standard logs. Rated 7.8 CVSS v3 (Important), it can lead to privilege escalation and infrastructure-wide code execution; Red Hat has issued fixes via RHSA-2026:28405 and RHSA-2026:28438.

LiteLLM: MCP Authentication Bypass via OAuth2 Passthrough Fallback | GitLab Advisory Database (GLAD)
CVE-2026-59822 is an authentication bypass in LiteLLM's MCP Streamable HTTP endpoint, where the OAuth2 passthrough fallback path replaced failed LiteLLM key validation with an empty UserAPIKeyAuth() object. An unauthenticated attacker could supply an arbitrary/fabricated Bearer token to establish an authenticated MCP session, then list and call configured MCP tools and access connected services. The issue is fixed in LiteLLM v1.84.0. Details →First reported infosecwriteups.com
Google fixing Android lock screen bug that lets Gemini send SMS without a PIN
Google is fixing an Android 16 lock screen bypass in which Gemini, accessible from the lock screen, can be tricked into sending SMS and WhatsApp messages without a PIN. Pressing Gemini's "Continue" prompt simultaneously with its "Add attachment" button lets an attacker with physical access dispatch messages and re-enable Gemini's access to previously disconnected apps, all while the device stays locked.

Wiz Uncovers Critical Access Bypass Flaw in AI-Powered Vibe Coding Platform Base44
Wiz disclosed a now-patched critical authentication bypass in Base44, an AI-powered 'vibe coding' platform owned by Wix, where supplying only a non-secret 'app_id' value to undocumented registration and email-verification endpoints let an attacker create a verified account for private applications. The flaw bypassed all authentication controls, including SSO, granting full access to private apps and their data; Wix fixed it within 24 hours of the July 9, 2025 disclosure, with no evidence of exploitation in the wild.

Shipping an OAuth-protected remote MCP server: the spec, 3 security bugs, and a Cloud Run gotcha
An engineering blog post from SkillDB describing how they turned their MCP server into a remote, OAuth-protected MCP server for Claude Desktop, covering the MCP authorization spec (RFC 9728 protected resource metadata, 401 Bearer challenge), three OAuth security bugs caught in review before launch, and a Cloud Run infrastructure issue.

Instagram account takeover exploit via support chatbot prompt injection (fixed)
Reports claim Meta's AI support agent for Instagram was granted account-modification permissions without identity verification, allowing attackers to manipulate the bot into changing account emails and bypassing 2FA, leading to live account takeovers. Multiple users reported losing accounts before the issue was reportedly patched. Details →First reported arstechnica.com
Millions of AI agents imperiled by critical vulnerability in open source package
A critical authentication-bypass vulnerability (CVE-2026-48710, dubbed BadHost) in the Starlette framework lets a single character injected into the HTTP Host header bypass path-based authorization. Because Starlette underpins FastAPI, vLLM, LiteLLM, and many MCP servers and agent harnesses, the flaw exposes millions of AI agents and their stored third-party credentials and sensitive data to trivial exploitation.
