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 2.17.4 runs a total of 414 security queries when configured with the Default suite (covering 161 CWE). The Extended suite enables an additional 131 queries (covering 35 more CWE).
CodeQL CLI¶ New Features¶CodeQL package management is now generally available, and all GitHub-produced CodeQL packages have had their version numbers increased to 1.0.0.
Removed local query variants. The results pertaining to local sources can be found using the non-local counterpart query. As an example, the results previously found by java/unvalidated-url-redirection-local can be found by java/unvalidated-url-redirection, if the local threat model is enabled. The removed queries are java/path-injection-local, java/command-line-injection-local, java/xss-local, java/sql-injection-local, java/http-response-splitting-local, java/improper-validation-of-array-construction-local, java/improper-validation-of-array-index-local, java/tainted-format-string-local, java/tainted-arithmetic-local, java/unvalidated-url-redirection-local, java/xxe-local and java/tainted-numeric-cast-local.
The “Use of unique pointer after lifetime ends” query (cpp/use-of-unique-pointer-after-lifetime-ends) no longer reports an alert when the pointer is converted to a boolean
The “Variable not initialized before use” query (cpp/not-initialised) no longer reports an alert on static variables.
The query go/incorrect-integer-conversion has now been restricted to only use flow through value-preserving steps. This reduces false positives, especially around type switches.
The alert message for the query “Trust boundary violation” (java/trust-boundary-violation) has been updated to include a link to the remote source.
The sanitizer of the query java/zipslip has been improved to include nodes that are safe due to having certain safe types. This reduces false positives.
Added models of gradio PyPI package.
Fixed a bug where very large TypeScript files would cause database creation to crash. Large files over 10MB were already excluded from analysis, but the file size check was not applied to TypeScript files.
Added support for data flow through side-effects on static fields. For example, when a static field containing an array is updated.
A bug has been fixed which meant that the query go/incorrect-integer-conversion did not consider type assertions and type switches which use a defined type whose underlying type is an integer type. This may lead to fewer false positive alerts.
A bug has been fixed which meant flow was not followed through some ranged for loops. This may lead to more alerts being found.
Added value flow models for the built-in functions append, copy, max and min using Models-as-Data. Removed the old-style models for max and min.
JDK version detection based on Gradle projects has been improved. Java extraction using build-modes autobuild or none is more likely to pick an appropriate JDK version, particularly when the Android Gradle Plugin or Spring Boot Plugin are in use.
Additional heuristics for a new sensitive data classification for private information (e.g. credit card numbers) have been added to the shared SensitiveDataHeuristics.qll library. This may result in additional results for queries that use sensitive data such as js/clear-text-storage-sensitive-data and js/clear-text-logging.
The request parameter of Flask SessionInterface.open_session method is now modeled as a remote flow source.

This may result in additional results for queries that use sensitive data such as py/clear-text-storage-sensitive-data and py/clear-text-logging-sensitive-data.

A Python MaD (Models as Data) row may now contain a dotted path in the type column. Like in Ruby, a path to a class will refer to instances of that class. This means that the summary ["foo", "Member[MyClass].Instance.Member[instance_method]", "Argument[0]", "ReturnValue", "value"] can now be written ["foo.MS_Class", "Member[instance_method]", "Argument[0]", "ReturnValue", "value"]. To refer to an actual class, one may add a ! at the end of the path.
