[Security] Bump activesupport from 5.2.3 to 5.2.5

[dependabot-preview]

Bumps activesupport from 5.2.3 to 5.2.5. This update includes a security fix.

Vulnerabilities fixed

Sourced from The Ruby Advisory Database.

Potentially unintended unmarshalling of user-provided objects in MemCacheStore and RedisCacheStore There is potentially unexpected behaviour in the MemCacheStore and RedisCacheStore where, when untrusted user input is written to the cache store using the raw: true parameter, re-reading the result from the cache can evaluate the user input as a Marshalled object instead of plain text. Vulnerable code looks like:

data = cache.fetch("demo", raw: true) { untrusted_string }

Versions Affected: rails < 5.2.5, rails < 6.0.4 Not affected: Applications not using MemCacheStore or RedisCacheStore. Applications that do not use the raw option when storing untrusted user input. Fixed Versions: rails >= 5.2.4.3, rails >= 6.0.3.1

Impact

Unmarshalling of untrusted user input can have impact up to and including RCE. At a minimum, this vulnerability allows an attacker to inject untrusted Ruby objects into a web application.

In addition to upgrading to the latest versions of Rails, developers should ensure that whenever they are calling Rails.cache.fetch they are using consistent values of the raw parameter for both

Patched versions: ~> 5.2.4, >= 5.2.4.3; >= 6.0.3.1 Unaffected versions: none
