Fixed prototype pollution vulnerability in merge function 2\. Improved input validation for template method 3\. Enhanced sanitization in defaultsDeep The Challenge ### Outdated dependencies create security risks & technical debt Meaningful Updates are Complex Often more complex, expensive, and strategic as other senior engineering tasks Backlogged Forever Is Not a Strategy Falling further behind takes you off the stable upgrade path and makes it even harder later Developer Capacity Is The Bottleneck Teams need tools that fix, instead of prioritize issues for later The Solution ### Updates that are safe and handled for you automatically Perform Effective Updates, Safely Intelligently select upgrades that model tradeoffs and prevent breaking changes. Deliver Completed Engineering Tasks Plan and execute like a senior engineer, including migrations and code adaption.

It's a good way to get rid of the low hanging fruit quickly and concentrate on the larger upgrades. ![Joel Merrick](https://fossa.com/joelmerrick.jpg) Joel Merrick DevOps Engineer & Cloud Architect ### We don't guess, we prove. Unlike generic bots that rely on surface-level heuristics, fossabot uses deep, code-aware analysis to determine exactly how a dependency update impacts your application. It doesn't just detect breaking changes — it verifies whether those changes affect your app at all. ![Fossabot researching](https://fossa.com/images/fossabot/fossabot-researching.svg) ##### Research ###### Map your code Every part of fossabot is tailored to your codebase, for personalized analysis. ###### Analyze dependencies fossabot builds a detailed graph of how you use each dependency's features. ##### Analyze ###### Detect breaking changes fossabot cross-references each update against your usage patterns. ###### Identify impact to your code fossabot pinpoints risk down to the exact functions, call sites, and workflows that break. ##### Update ###### Suggest fixes and migrations fossabot commits code fixes or shares migration steps, right in the PR. ###### Escalate only when needed fossabot flags complex issues clearly and hands them over to your team — with context needed to make a confident call. ### Frequently Asked Questions fossabot can replace or run alongside tools like Dependabot, Renovate, or Snyk to analyze dependency updates. fossabot works best when it is able to pre-plan and propose an upgrade to provide the best risk vs reward for your app. When used with Dependabot, Renovate, or Snyk, fossabot provides a comprehensive view of the impact without being involved in selecting the upgraded versions. Yes, fossabot will flag malicious dependencies as part of its analysis. fossabot is more proactive than other systems because it acts on both live data and malicious package databases. fossabot may suggest code changes in the analyzed PR (if needed) but you always review and approve them before merging. This is part of our philosophy to deliver completed work, saving you time. We built fossabot to be cautious by default. It flags high-risk changes for human review and only acts on safe, low-risk updates. fossabot supports a [variety of ecosystems and languages](https://docs.fossa.com/docs/fossabot-supported-ecosystems) with continuous improvements and additions. Yes, fossabot works with most GitHub and GitLab product offerings. #### Let fossabot handle the hard parts of dependency updates Connect your repositories and start merging updates 10x faster.
