Agentic AI Security: Credentials and Permissions Define the Blast Radius

In July 2026, researchers at Noma Labs coaxed GitHub's new Agentic Workflows into leaking data from a private repository. It wasn’t from malware. They created a plausible-looking issue in a public repository containing instructions for the agent to retrieve information from other repositories in the organization. After testing variations of the prompt, they found that adding one word, "Additionally," was enough to get past GitHub's guardrails.

Validity-Override API Tutorial: Confirm If a Leaked Secret Is Still Exploitable

GitGuardian's validity-override API lets security and engineering teams tell GitGuardian whether an exposed credential is actually valid, even when automatic checks mark it as Failed to Check. Secrets tied to internal services, private APIs, or systems GitGuardian cannot reach often fall into this category. GitGuardian automatically validates most supported credential types, but when it cannot, teams can now perform their own validation and feed the result back into the platform.

Introducing GitGuardian Developer Endpoint Protection: Inventory Every Laptop's Credentials

A single compromised laptop can mean weeks of manual credential hunting, or hours of clear, prioritized action. See how GitGuardian Developer Endpoint Protection inventories every credential on a developer's machine so your security team can map the blast radius fast. When an attacker compromises a developer laptop, traditional endpoint tools cannot tell you what credentials were exposed.

Developer Endpoint Protection: Stop Secrets Leaking From Laptops | GitGuardian

Every developer laptop is a credential store: secrets hide in.env files, config files, and shell history, and every AI agent on the machine keeps adding more. Most teams already scan repositories and CI pipelines for secrets, but a secret lands on the laptop long before it reaches either one, and that's the place nobody scans. GitGuardian's Developer Endpoint Protection closes that gap.

Securing Agentic AI Workflows in n8n: From Leaked API Keys to Encryption Key Compromise

A leaked n8n API key is only the start. GitGuardian's research traces the full chain, from exposed tokens and weak keys to CVE-2026-25053 and the N8N_ENCRYPTION_KEY that protects every stored credential, then lays out a hardened configuration to break it.
