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.
