↗️ activesupport (indirect, 8.1.2 → 8.1.3) · Repo · Changelog

Security Advisories 🚨

🚨 Rails Active Support has a possible ReDoS vulnerability in number_to_delimited

Impact

NumberToDelimitedConverter used a regular expression with gsub! to insert thousands delimiters. This could produce quadratic time complexity on long digit strings.

Releases

The fixed releases are available at the normal locations.

🚨 Rails Active Support has a possible XSS vulnerability in SafeBuffer#%

Impact

SafeBuffer#% does not propagate the @html_unsafe flag to the newly created buffer. If a SafeBuffer is mutated in place (e.g. via gsub!) and then formatted with % using untrusted arguments, the result incorrectly reports html_safe? == true, bypassing ERB auto-escaping and possibly leading to XSS.

Releases

The fixed releases are available at the normal locations.

🚨 Rails Active Support has a possible DoS vulnerability in its number helpers

Impact

Active Support number helpers accept strings containing scientific notation (e.g. 1e10000), which when converted to a string could be expanded into extremely large decimal representations. This can cause excessive memory allocation and CPU consumption when the expanded number is formatted, possibly resulting in a DoS vulnerability.

Releases

The fixed releases are available at the normal locations.

↗️ json (indirect, 2.18.1 → 2.19.3) · Repo · Changelog

Security Advisories 🚨

🚨 Ruby JSON has a format string injection vulnerability

Impact

A format string injection vulnerability than that lead to denial of service attacks or information disclosure, when the allow_duplicate_key: false parsing option is used to parse user supplied documents.

This option isn't the default, if you didn't opt-in to use it, you are not impacted.

Patches

Patched in 2.19.2.

Workarounds

The issue can be avoided by not using the allow_duplicate_key: false parsing option.

What's Changed
