1-13: Consider enhancing the security message with specific recommendationsThe message effectively warns about hard-coded secrets but could be more actionable by:
- Mentioning specific secure alternatives (e.g., Rails credentials, encrypted credentials)
- Adding links to Ruby-specific secure configuration guides
message: >- A secret is hard-coded in the application. Secrets stored in source code, such as credentials, identifiers, and other types of sensitive data, can be leaked and used by internal or external malicious actors. Use environment variables to securely provide credentials and other secrets or - retrieve them from a secure vault or Hardware Security Module (HSM). + retrieve them from a secure vault or Hardware Security Module (HSM). + Consider using Rails.application.credentials, Rails.application.secrets, + or encrypted credentials in Rails applications. note: >- [CWE-798] Use of Hard-coded Credentials.

2-4: Enhance test coverage with additional valid casesConsider adding more valid test cases to demonstrate recommended approaches:
valid: - | redis_ok1 = Redis.new(username: 'myname', password: ENV["PASS"]) + - | + redis_ok2 = Redis.new(password: Rails.application.credentials.redis_password) + - | + redis_ok3 = Redis.new(password: Rails.application.secrets.redis_password)
5-15: Add edge cases to invalid test casesConsider adding edge cases to ensure comprehensive coverage:
invalid: - | require "redis" redis = Redis.new(password: "mysecret") - | require "redis" redis1 = Redis.new(username: 'myname', password: 'mysecret') - | require "redis" pass = 'password' redis1 = Redis.new(username: 'myname', password: pass) + - | + require "redis" + redis = Redis.new(password: '') # Empty password + - | + require "redis" + redis = Redis.new(password: nil) # Nil passwordrules/ruby/security/force-ssl-false-ruby.yml (1)
13-13: Enhance pattern matching for better coverageThe current pattern might miss variations in SSL configuration. Consider expanding it to catch more cases:
- pattern: config.force_ssl = false + patterns: + - pattern: config.force_ssl = false + - pattern: config.ssl_options = { :secure => false } + - pattern: config.ssl_options = { secure: false }tests/ruby/force-ssl-false-ruby-test.yml (1)
1-11: Enhance test coverage with additional scenariosWhile the basic test cases are good, consider adding more scenarios to improve coverage:
id: force-ssl-false-ruby valid: - | def bad_ssl config.force_ssl = true end + - | + def ssl_options + config.ssl_options = { secure: true } + end invalid: - | def bad_ssl config.force_ssl = false end + - | + def multiple_settings + config.force_ssl = true + config.force_ssl = false # Should catch even if set to true first + end + - | + def ssl_options + config.ssl_options = { secure: false } + endrules/ruby/security/ruby-faraday-hardcoded-secret-ruby.yml (1)
120-122: Fix typo in pattern name commentThe comment doesn't match the pattern name. It should reflect that it's for a variable
$PSDinstead of a string literal.- # $X.request :authorization, $BEARER, "..." + # $X.request :authorization, $BEARER, $PSDtests/ruby/ruby-faraday-hardcoded-secret-ruby-test.yml (1)
9-30: Consider adding test case for non-hardcoded token auth with optionsThe test suite would benefit from a valid case showing token auth with options but using an environment variable instead of a hardcoded token.
Add this test case to the valid section:
valid: + - | + require "faraday" + token = ENV['API_TOKEN'] + conn.request :token_auth, token, **options

1-158: LGTM! Snapshots are well-structured and accurate
The snapshots provide precise source mapping for each test case, which will help with accurate error reporting.

1-11: Ensure snapshot maintenance aligns with test cases
The snapshot looks good for the current test case, but remember to update it when adding the suggested additional test scenarios. The snapshot should maintain parity with all test cases.

4-8: Verify rule patterns for test parameter handling
The valid test cases include a test parameter, but the rule patterns in ruby-faraday-hardcoded-secret-ruby.yml don't explicitly handle this case. This might cause false positives.

74-80: Verify source positions for multi-line snippets
The source positions for multi-line code blocks might need adjustment. For example, in this block, the end position (90) seems to include newlines, while other blocks handle newlines differently.
✅ Verification successful
Let me gather more information about the specific file and its end positions to verify the consistency.
Source positions are correctly calculated
After analyzing the file, the end positions are consistently calculated including newlines and are correct for all snippets. For example:
- Single-line snippets like
require "faraday"have end: 17 - Multi-line snippets have end positions that account for all characters including newlines
- The specific snippet in question (end: 90) correctly accounts for three lines of code including newlines
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Check consistency of end positions in multi-line snippets
rg "end: \d+" tests/__snapshots__/ -A 1 | grep -B 1 "source: |"
Length of output: 2753
Script:
#!/bin/bash
# Get all source blocks with their end positions from the specific file
rg "source: \||-|end: \d+" tests/__snapshots__/ruby-faraday-hardcoded-secret-ruby-snapshot.yml -B 1 -A 1
