Description

What do you expect to see or happen. What happens instead?

We have a mirror repository of your Glitchtip front-end repository and we have Dependabot alerts enabled we noticed a lot of CVE issues with outdated package dependencies and we wish to get these issue fixed upstream. We also notice container image scans are high in with CVE's. Are there any plans to address these security issues?

What do you think should be changed? This could be a code change or a documentation change. Are you interested in doing this change yourself? Do you need assistance getting up to speed on how to develop for GlitchTip?
