Getting started with Mantis, our open-source bug finding-and-fixing
AI models have clearly proven their ability to discover and exploit vulnerabilities without much, if any, human assistance.

Getting started with Mantis, our open-source bug finding-and-fixing harness
Google has announced the release of Mantis, an open-source security framework designed to help defenders find and patch software vulnerabilities using artificial intelligence. This release comes as artificial intelligence systems demonstrate an increasing capacity to autonomously discover and exploit security weaknesses in code without human intervention.

Why it matters
To help defenders gain the advantage with AI, we built the Mantis harness to automate the discovery, triage, reproduction, and patching of software vulnerabilities. Available to all as an open-source framework, Mantis is part of Google’s internal approach to find and fix vulnerabilities at machine-speed.
Who is affected
It creates a more effective scalable, context-aware repository analysis. As we detailed in June, it examines the history of the repository to learn from past security fixes and automatically builds up architectural and threat model documentation, even if these are not provided.
What to watch next
It constructs a hierarchical security summary tree, condensing individual files into directory and root-level summaries. See the full write-up from Google Cloud Blog via the source link for quotes and complete context.
Developer Action Items
- ☐ Inventory whether Google / Framework runs in prod, CI, staging, or on laptops before you debate severity.
- ☐ Confirm the vendor's fixed build for Google / Framework from Google Cloud Blog, then schedule the patch window.
- ☐ If you cannot patch today, isolate the service, rotate tokens that sat on the affected surface, and raise the logging floor.
- ☐ Record the decision and residual risk so the next on-call does not re-litigate whether you are exposed.
