[Security] Bump activestorage from 5.2.3 to 6.0.3.3

[dependabot-preview[bot]]

Bumps activestorage from 5.2.3 to 6.0.3.3. This update includes a security fix.

Vulnerabilities fixed

Sourced from The Ruby Advisory Database.

Circumvention of file size limits in ActiveStorage There is a vulnerability in ActiveStorage's S3 adapter that allows the Content-Length of a direct file upload to be modified by an end user.

Versions Affected: rails < 5.2.4.2, rails < 6.0.3.1 Not affected: Applications that do not use the direct upload functionality of the ActiveStorage S3 adapter. Fixed Versions: rails >= 5.2.4.3, rails >= 6.0.3.1

Impact

Utilizing this vulnerability, an attacker can control the Content-Length of an S3 direct upload URL without receiving a new signature from the server. This could be used to bypass controls in place on the server to limit upload size.

Workarounds

This is a low-severity security issue. As such, no workaround is necessarily until such time as the application can be upgraded.

Patched versions: ~> 5.2.4.3; >= 6.0.3.1 Unaffected versions: none
