CodeQL 2.23.7 (2025-12-05)¶

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 2.23.7 runs a total of 491 security queries when configured with the Default suite (covering 166 CWE). The Extended suite enables an additional 135 queries (covering 35 more CWE). 6 security queries have been added with this release.

CodeQL CLI¶

Deprecations¶

The --save-cache flag to codeql database run-queries and other commands that execute queries has been deprecated. This flag previously instructed the evaluator to aggressively write intermediate results to the disk cache, but now has no effect.

Query Packs¶

Minor Analysis Improvements¶

Java/Kotlin¶

Operations that extract only a fixed-length prefix or suffix of a string (for example, substring in Java or take in Kotlin), when limited to a length of at most 7 characters, are now treated as sanitizers for the java/sensitive-log query.

JavaScript/TypeScript¶

Fixed a bug in the Next.js model that would cause the analysis to miss server-side taint sources in the app/pages folder.

Rust¶

The rust/access-invalid-pointer query has been improved with new flow sources and barriers.

New Queries¶

Golang¶

The go/cookie-http-only-not-set query has been promoted from the experimental query pack. This query was originally contributed to the experimental query pack by @edvraa.
A new query go/cookie-secure-not-set has been added to detect cookies without the Secure flag set.
Added a new query, go/weak-crypto-algorithm, to detect the use of a broken or weak cryptographic algorithm. A very simple version of this query was originally contributed as an experimental query by @dilanbhalla.
Added a new query, go/weak-sensitive-data-hashing, to detect the use of a broken or weak cryptographic hash algorithm on sensitive data.

Rust¶

Added a new query rust/xss, to detect cross-site scripting security vulnerabilities.
Added a new query rust/disabled-certificate-check, to detect disabled TLS certificate checks.
Added three example queries (rust/examples/empty-if, rust/examples/simple-sql-injection and rust/examples/simple-constant-password) to help developers learn to write CodeQL queries for Rust.

Language Libraries¶

Bug Fixes¶

Python¶

Fixed a bug in the Python extractor’s import handling where failing to find an import in find_module would cause a KeyError to be raised. (Contributed by @akoeplinger.)

Breaking Changes¶

Rust¶

The type DataFlow::Node is now based directly on the AST instead of the CFG, which means that predicates like asExpr() return AST nodes instead of CFG nodes.

Minor Analysis Improvements¶

C/C++¶

The class DataFlow::FieldContent now covers both union and struct/class types. A new predicate FieldContent.getAField has been added to access the union members associated with the FieldContent. The old FieldContent has been renamed to NonUnionFieldContent.

C#¶

Improved stability when downloading .NET versions by setting appropriate environment variables for dotnet commands. The correct architecture-specific version of .NET is now downloaded on ARM runners.
Compilation errors are now included in the debug log when using build-mode none.
Added a new extractor option to specify a custom directory for dependency downloads in buildless mode. Use -O buildless_dependency_dir=<path> to configure the target directory.

JavaScript/TypeScript¶

JavaScript DataFlow::globalVarRef now recognizes document.defaultView as an alias of window, allowing flows such as document.defaultView.history.pushState(...) to be modeled and found by queries relying on globalVarRef("history").

Rust¶

Added more detailed models for std::fs and std::path.

Deprecated APIs¶

Java/Kotlin¶

The SSA interface has been updated and all classes and several predicates have been renamed. See the qldoc for more specific migration information.
