4aee0b3c87 Python: add new shared-CFG-backed control flow graph
Preparatory refactor for the shared-CFG dataflow migration. Adds the
new Python CFG library additively, without changing any production
behaviour.

Library additions:

- semmle.python.controlflow.internal.AstNodeImpl — mediates between
  the Python AST and the shared codeql.controlflow.ControlFlowGraph
  signature. Wraps Python's Stmt/Expr/Scope/Pattern and adds two
  synthetic kinds of node (BlockStmt for body slots, intermediate
  nodes for multi-operand boolean expressions).

- semmle.python.controlflow.internal.Cfg — public facade
  re-exposing the same API surface as semmle/python/Flow.qll
  (ControlFlowNode, CallNode, BasicBlock, NameNode, DefinitionNode,
  CompareNode, ...), backed by the shared CFG.

- lib/printCfgNew.ql — debug/visualisation query for the new CFG.

- consistency-queries/CfgConsistency.ql — consistency query running
  the shared CFG's standard checks against Python.

Shared library:

- shared.controlflow.ControlFlowGraph — adds two defaulted
  getWhileElse / getForeachElse predicates to AstSig so Python can
  model while-else / for-else (no behavioural change for other
  languages).

Test additions:

- ControlFlow/bindings/* — annotation-driven SSA-binding tests for
  the new CFG (annassign, compound, comprehension, decorated,
  except_handler, imports, match_pattern, parameters, simple,
  type_params, walrus_starred, with_stmt, dead_under_no_raise).

- ControlFlow/store-load/* — basic store/load coverage.

- ControlFlow/evaluation-order/NewCfg*.ql — mirrors of the existing
  OldCfg evaluation-order self-validation suite, run against the
  new CFG via NewCfgImpl.qll.

- Minor extensions to existing test_if.py / test_boolean.py +
  cosmetic .expected churn on a handful of OldCfg tests.

No dataflow, SSA, or production query is migrated yet — that lands in
follow-up PRs. The new CFG library has zero callers in lib/ and src/.

Verified by:
- All lib + src + consistency-queries compile clean (367 queries).
- All 56 ControlFlow library-tests pass.
- All 474 dataflow + PointsTo library-tests + consistency tests pass.
- syntax_error/CONSISTENCY/CfgConsistency passes.

0623acc7f5 Python: qualify Flow.qll's AST references with Py:: prefix
Preparatory refactor for the shared-CFG dataflow migration. Switches
'import python' to 'import python as Py' inside Flow.qll, and qualifies
every AST-class reference (Expr, Bytes, Dict, AssignExpr, Compare,
Module, Scope, Call, Attribute, SsaVariable, AugAssign, etc.) with the
Py:: prefix.

Flow.qll's own CFG types (ControlFlowNode, BasicBlock, CallNode,
NameNode, DefinitionNode, CompareNode, ...) keep their unqualified
names — they remain the public CFG API exported from this file.

This is a semantic noop: the qualification was applied mechanically by
script and no name resolution changes. Verified by:
- All 361 lib/ + src/ queries compile clean.
- All 186 ControlFlow + PointsTo + dataflow library-tests pass.

dc5aa8e0f5 Python: deprecate Function.getAReturnValueFlowNode() and rewrite internal callers
Follow-up to the getAFlowNode deprecation in the same PR: same AST→legacy-CFG
bridge pattern. The 11 internal call sites (across objects/, types/,
frameworks/, and TypeTrackingImpl) are rewritten to bind a `Return ret`
explicitly, then constrain via `ret.getScope() = f and n.getNode() = ret.getValue()`.

The predicate itself is preserved with a deprecation note so external
users do not experience churn.

Semantic noop.

db1e5035b4 Python: deprecate AstNode.getAFlowNode() and rewrite internal callers
Preparatory refactor for the shared-CFG dataflow migration.

Deprecates the AstNode.getAFlowNode() cached predicate on the public
Python QL API and rewrites all ~140 internal callers across lib/, src/,
test/, and tools/ from `expr.getAFlowNode() = cfgNode` to
`cfgNode.getNode() = expr`, using ControlFlowNode.getNode() which
already exists in Flow.qll.

The predicate itself is preserved (with a deprecation note pointing at
the new pattern) so external users do not experience churn — they can
migrate at their own pace and the AST/CFG hierarchies still get the
intended untangling once the deprecation eventually elapses.

Semantic noop verified by:
- All 361 lib/ + src/ queries compile clean.
- All 122 ControlFlow + PointsTo library-tests pass.
- All 64 dataflow library-tests pass.
- All 113 Variables/Exceptions/Expressions/Statements/Functions/Imports/
  Security/CWE-798/ModificationOfParameterWithDefault query-tests pass.

7a3f546587 Python: inline init_module_submodule_defn into ImportResolution
The new-dataflow ImportResolution module only used
semmle.python.essa.SsaDefinitions for the 5-line helper predicate
SsaSource::init_module_submodule_defn. Inline it locally and drop the
dependency on legacy SsaDefinitions. This is the only remaining direct
import of semmle.python.essa.* in the new dataflow stack, so dropping
it makes the layering cleaner.

Semantic noop on the current SSA: SsaSourceVariable.getName() and
GlobalVariable.getId() both project the same DB column
(variable(_,_,result)), and the old call's 'init.getEntryNode() = f'
join was just constraining init = package via Scope.getEntryNode()'s
functional uniqueness. RA dump of accesses.ql confirms only the
expected predicate-rename shuffle; all 70 dataflow + ApiGraphs library
tests pass.

This factors out commit 8cab5a20f2 from the larger shared-CFG
migration #21925.

821325b7e5 Python: simplify decorator-detection predicates to pure AST match
The internal predicates that identify `@staticmethod`, `@classmethod` and
`@property` decorators previously required the decorator's `NameNode` to
satisfy `isGlobal()` (i.e. no SSA def reaches the decorator's name use).
That filter was correct but unnecessarily indirect: these three names
are builtins, and even when a class body redefines one, the class body
has not started executing at the decorator position, so Python uses the
builtin.

Match the decorator's AST `Name` directly instead, dropping the CFG/SSA
detour. The slight semantic change — `isGlobal()` would have rejected
module-level shadowing of these builtins — is negligible in practice
and explicitly documented in the change note.

`hasContextmanagerDecorator` and `hasOverloadDecorator` keep the
`NameNode.isGlobal()` check because their target names (`contextmanager`,
`overload`) are imported, not builtin, and local shadowing is a real
concern.

4d2296d4f0 Shared CFG: add defaulted getWhileElse/getForeachElse/getCatchType to AstSig
Adds three new defaulted signature predicates to the shared CFG library:

- getWhileElse / getForeachElse: `else` block of a while/for loop, if
  any (used by Python's `while-else` / `for-else` constructs).
- getCatchType: type expression of a catch clause, if any (used by
  Python's `except SomeExpr:` where the catch type is a runtime
  expression that needs CFG evaluation).

Each predicate defaults to `none()`, so behaviour is unchanged for any
language that doesn't override it (verified by re-running
java/ql/test/library-tests/controlflow/).

The Make0 succession rules are extended:
- WhileStmt/ForeachStmt: route the loop-exit edge through the else
  block before reaching the after-position.
- CatchClause: route the matching-evaluation through the type
  expression (if present) before reaching the after-value position.

==========================
CodeQL 2.25.6 (2026-06-04)
==========================
.. contents:: Contents
:depth: 2
:local:
:backlinks: none
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 <https://github.blog/tag/code-scanning/>`__, `relevant GitHub Changelog updates <https://github.blog/changelog/label/application-security/>`__, `changes in the CodeQL extension for Visual Studio Code <https://marketplace.visualstudio.com/items/GitHub.vscode-codeql/changelog>`__, and the `CodeQL Action changelog <https://github.com/github/codeql-action/blob/main/CHANGELOG.md>`__.
Security Coverage
-----------------
CodeQL 2.25.6 runs a total of 496 security queries when configured with the Default suite (covering 169 CWE). The Extended suite enables an additional 131 queries (covering 32 more CWE).
CodeQL CLI
----------
Improvements
~~~~~~~~~~~~
* When the :code:`git` executable is available, CodeQL can now obtain configuration and queries from SHA-256 Git repositories, and infer Git metadata about them.
Miscellaneous
~~~~~~~~~~~~~
* The build of Eclipse Temurin OpenJDK that is used to run the CodeQL CLI has been updated to version 21.0.11.
Query Packs
-----------
Bug Fixes
~~~~~~~~~
GitHub Actions
""""""""""""""
* Adjusted (minor) help file descriptions for queries: :code:`actions/untrusted-checkout/critical`, :code:`actions/untrusted-checkout/high`, :code:`actions/untrusted-checkout/medium`. Clarified wording on a minor point, added one more listed resource and added one more recommendation for things to check.
Major Analysis Improvements
~~~~~~~~~~~~~~~~~~~~~~~~~~~
GitHub Actions
""""""""""""""
* Adjusted :code:`actions/untrusted-checkout/critical` to align more with other untrusted resource queries, where the alert location is the location where the artifact is obtained from (the checkout point). This aligns with the other 2 related queries. This will cause the same alerts to re-open for closed alerts of this query.
Minor Analysis Improvements
~~~~~~~~~~~~~~~~~~~~~~~~~~~
GitHub Actions
""""""""""""""
* Altered the alert message for clarity for queries: :code:`actions/untrusted-checkout/critical`, :code:`actions/untrusted-checkout/high`.
* The :code:`actions/unpinned-tag` query now recognizes 64-character SHA-256 commit hashes as properly pinned references, in addition to 40-character SHA-1 hashes.
Query Metadata Changes
~~~~~~~~~~~~~~~~~~~~~~
GitHub Actions
""""""""""""""
* Reversed adjustment of the name of :code:`actions/untrusted-checkout/high`, but kept the portion of the previous change for the word "trusted" to "privileged". Added a missing "a" to phrasing in :code:`actions/untrusted-checkout/high` and :code:`actions/untrusted-checkout/medium`.
Language Libraries
------------------
Major Analysis Improvements
~~~~~~~~~~~~~~~~~~~~~~~~~~~
Swift
"""""
* Upgraded to allow analysis of Swift 6.3.2.
Minor Analysis Improvements
~~~~~~~~~~~~~~~~~~~~~~~~~~~
C/C++
"""""
* Added flow source models for :code:`scanf_s` and related functions.
* Added a :code:`Call` column to :code:`LocalFlowSourceFunction::hasLocalFlowSource` and :code:`RemoteFlowSourceFunction::hasRemoteFlowSource`. The old predicates without a :code:`Call` column continue to be supported.
C#
""
* Full support for C# 14 / .NET 10. All new language features are now supported by the extractor. The QL library and data flow analysis now support the new C# 14 language constructs and include generated Models as Data (MaD) models for the .NET 10 runtime.
* C# 14: Added support for user-defined instance increment/decrement operators.
Java/Kotlin
"""""""""""
* Added LLM-generated source and sink models for :code:`org.apache.avro`.
JavaScript/TypeScript
"""""""""""""""""""""
* The sensitive data heuristics used to identify code that handles passwords and private data have been improved. Most of the changes permit more variations of established patterns, thereby finding more sensitive data. Queries that use the sensitive data library (for example :code:`js/clear-text-logging`) may find more correct results and fewer false positive results after these changes.
Python
""""""

Queries that use the sensitive data library (for example :code:`swift/cleartext-logging`) may find more correct results and fewer false positive results after these changes.
GitHub Actions
""""""""""""""
* The GitHub Actions analysis now recognizes more Bash regex checks that restrict a value to alphanumeric characters, including regexes like :code:`^[0-9a-zA-Z]{40}([0-9a-zA-Z]{24})?$` which check for a SHA-1 or SHA-256 hash. This may reduce false positive results where command output is validated with grouped or optional alphanumeric patterns before being used.
Rust
""""

Queries that use the sensitive data library (for example :code:`rust/cleartext-logging`) may find more correct results and fewer false positive results after these changes.
Deprecated APIs
~~~~~~~~~~~~~~~
C/C++
"""""
* The :code:`UsingAliasTypedefType` class has been deprecated. Use :code:`TypeAliasType` instead.
New Features
~~~~~~~~~~~~
C/C++
"""""
* Added a :code:`getOriginalTemplate` predicate to :code:`TemplateClass`, :code:`TemplateFunction`, :code:`TemplateVariable`, and :code:`AliasTemplateType`, which yields the class member template the template was generated from. The predicates only have results for templates that are members of class template instantiations.
* Added :code:`AliasTemplateType` and :code:`AliasTemplateInstantiationType` classes, representing C++ alias templates and their instantiations.
