CodeQL 2.11.4 (2022-11-24)

This is an overview of changes in the CodeQL CLI and relevant CodeQL query and library packs. For additional updates on changes to the CodeQL code scanning experience, check out the code scanning section on the GitHub blog, relevant GitHub Changelog updates, changes in the CodeQL extension for Visual Studio Code, and the CodeQL Action changelog.

Security Coverage

CodeQL 2.11.4 runs a total of 361 security queries when configured with the Default suite (covering 150 CWE). The Extended suite enables an additional 112 queries (covering 32 more CWE). 4 security queries have been added with this release.

CodeQL CLI

Potentially Breaking Changes

  • CodeQL 2.11.1 to 2.11.3 contained a bug in indirect build tracing on Windows when using codeql database init with the --trace-process-level flag. In these versions, when --trace-process-level was set to a value greater than zero, (or left at the default value of 1), CodeQL attempted to inject its build tracer at a higher level in the process tree than the requested process level. This could lead to errors of the form “No source code found” or “Process tree ended before reaching required level”. From 2.11.4 onwards, the CodeQL build tracer is injected at the requested process level.

Deprecations

  • The --[no-]fast-compilation option to codeql test run is now deprecated.

New Features

  • Kotlin support is now in beta. This means that Java analyses will also include Kotlin code by default. Kotlin support can be disabled by setting CODEQL_EXTRACTOR_JAVA_AGENT_DISABLE_KOTLIN to true in the environment.

Query Packs

Bug Fixes

JavaScript/TypeScript

  • Fixed a bug that would cause the extractor to crash when an import type is used in the extends clause of an interface.
  • Fixed an issue with multi-line strings in YAML files being associated with an invalid location, causing alerts related to such strings to appear at the top of the YAML file.

Minor Analysis Improvements

JavaScript/TypeScript

  • Added support for @hapi/glue and Hapi plugins to the frameworks/Hapi.qll library.

Ruby

  • The rb/sql-injection query now considers consider SQL constructions, such as calls to Arel.sql, as sinks.

New Queries

Java/Kotlin

  • The query java/insufficient-key-size has been promoted from experimental to the main query pack. Its results will now appear by default. This query was originally submitted as an experimental query by @luchua-bc.
  • Added a new query, java/android/sensitive-keyboard-cache, to detect instances of sensitive information possibly being saved to the Android keyboard cache.

Ruby

  • Added a new query, rb/shell-command-constructed-from-input, to detect libraries that unsafely construct shell commands from their inputs.

Language Libraries

Major Analysis Improvements

JavaScript/TypeScript

  • Added support for TypeScript 4.9.

Minor Analysis Improvements

C#

  • The [Summary|Sink|Source]ModelCsv classes have been deprecated and Models as Data models are defined as data extensions instead.

Java/Kotlin

  • The ReDoS libraries in semmle.code.java.security.regexp has been moved to a shared pack inside the shared/ folder, and the previous location has been deprecated.
  • Added data flow summaries for tainted Android intents sent to activities via Activity.startActivities.

Python

  • The ReDoS libraries in semmle.code.python.security.regexp have been moved to a shared pack inside the shared/ folder, and the previous location has been deprecated.

Ruby

  • Data flow through the ActiveSupport extension Enumerable#index_by is now modeled.
  • The codeql.ruby.Concepts library now has a SqlConstruction class, in addition to the existing SqlExecution class.
  • Calls to Arel.sql are now modeled as instances of the new SqlConstruction concept.
  • Arguments to RPC endpoints (public methods) on subclasses of ActionCable::Channel::Base are now recognized as sources of remote user input.
  • Taint flow through the ActiveSupport extensions Hash#reverse_merge and Hash:reverse_merge!, and their aliases, is now modeled more generally, where previously it was only modeled in the context of ActionController parameters.
  • Calls to logger in ActiveSupport actions are now recognised as logger instances.
  • Calls to send_data in ActiveSupport actions are recognised as HTTP responses.
  • Calls to body_stream in ActiveSupport actions are recognised as HTTP request accesses.
  • The ActiveSupport extensions Object#try and Object#try! are now recognised as code executions.

New Features

Java/Kotlin

  • Kotlin support is now in beta. This means that Java analyses will also include Kotlin code by default. Kotlin support can be disabled by setting CODEQL_EXTRACTOR_JAVA_AGENT_DISABLE_KOTLIN to true in the environment.
  • The new string Compilation.getInfo(string) predicate provides access to some information about compilations.

Shared Libraries

Minor Analysis Improvements

Regular Expression Analysis

  • Initial release. Extracted common regex related code, including the ReDoS analysis, into a library pack to share code between languages.
