Summary by fossabot

I recommend merging this lodash update from 4.17.20 to 4.17.21. This is a patch release that fixes several security vulnerabilities and includes performance improvements. Your application's usage patterns are compatible with this update.

  • Analyzed 47 files using lodash utilities across components/, utils/, and services/
  • Verified no deprecated methods or breaking changes affect your codebase

Change Details

Security Fixes (3)

1. 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Outdated dependencies create security risks & technical debt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.

Continuous Maintenance

Proactive updates reduce your app's unmaintained surface area

Review Dependency PRs

Automatically analyze PRs alongside other updaters to boost merge confidence.

Problem

Your repo is flooded with update PRs. Many fail and require significant time to track down breaking changes. Dependabot and similar tools don't understand your app's code, leaving your team guessing about what is safe to merge.

Summary by fossabot

I recommend merging this react-xml-viewer update from 2.0.4 to 3.0.1. Despite this being a major version upgrade with a breaking change, the codebase only uses basic config and avoids all deprecated APIs. It also bring support for newer Node versions.

  • Analyzed the two pages that use the XML viewer: Debug.tsx and Usage.tsx
  • Searched the entire codebase for removed API usage patterns

Change Details

Safe Breaking Changes (1)

1. The renamed initialCollapsedDepth prop isn't used anywhere in the codebase.

Problem

Your app has 100+ stale dependencies and you're falling further behind each day. Reviewing and updating them manually is time-consuming and perpetually stays on the backlog.

Remediate Vulnerabilities

Fix security alerts as they're found — and merge faster with built-in breaking change detection.

Problem

Your repo has security vulnerabilities. You're getting pressure to update ASAP. The fix touches many pages across a few teams, and it's not clear if any will break.

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.

Frequently Asked Questions

Not quite. fossabot runs alongside tools like Dependabot, Renovate or Snyk, to analyze the dependency updates and do the heavy lifting to provide a comprehensive view of the impact.

Yes, fossabot will flag malicious dependencies as part of its analysis. fossabot is more reactive 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 is currently focused on JavaScript/TypeScript and npm/yarn/pnpm. We're working on adding support for more languages and package managers.

Yes, fossabot works with GitHub. GitLab support is coming soon.
