+==========================
+
+.. 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.

+
+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.

+
+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.

+
+<overview>
+    <p>
+        Server-side request forgery (SSRF) guards frequently reject requests to internal
+        addresses by checking the request host against a denylist of private, loopback and
+        cloud-metadata IPv4 ranges. When such a guard inspects only the dotted-quad IPv4 form
+        and never unwraps IPv6-transition representations, it can be bypassed: the host
+        validator classifies the address as public, but the operating system routes the
+        connection to the embedded internal IPv4 endpoint.
+    </p>
+    <p>
+        The affected forms include IPv4-mapped IPv6 (<code>::ffff:169.254.169.254</code>),
+        NAT64 (<code>64:ff9b::a9fe:a9fe</code>) and 6to4 (<code>2002::</code>). A URL such as
+        <code>http://[::ffff:169.254.169.254]/</code> passes a dotted-quad denylist unchanged
+        while still reaching the internal address.
+    </p>
+</overview>
+
+<recommendation>
+    <p>
+        Normalize the host before validating it: parse the address with a transition-aware
+        library and unwrap IPv4-mapped, NAT64 and 6to4 forms to their embedded IPv4 address,
+        then apply the private-range check to the normalized value. Libraries such as
+        <code>ipaddr.js</code> classify these forms correctly via their range API, and
+        SSRF-protection libraries such as <code>request-filtering-agent</code> apply the check
+        after DNS resolution. Validate the resolved address rather than the textual host.
+    </p>
+</recommendation>
+
+<example>
+    <p>
+        The following guard rejects private IPv4 ranges using the <code>private-ip</code>
+        package, which inspects the textual IPv4 form only. An attacker supplies
+        <code>::ffff:169.254.169.254</code>, which the guard classifies as public, but the
+        request still reaches the internal metadata endpoint.
+    </p>
+
+    <sample src="examples/SsrfIpv6TransitionIncompleteGuardBad.js"/>
+
+    <p>
+        The following guard parses the host with a transition-aware classifier, so the
+        embedded internal IPv4 address is detected regardless of the transition form used.
+    </p>
+
+    <sample src="examples/SsrfIpv6TransitionIncompleteGuardGood.js"/>

Code that shadows these three builtin decorators at the module-scope will now be classified by the decorator name alone; in practice, shadowing these names is extremely rare and the call-graph results are unchanged.

tonghuaroot	e93bc11f6f	Add experimental JS query for SSRF guards missing IPv6-transition unwrap Add javascript/ssrf-ipv6-transition-incomplete-guard, an experimental @kind problem query that flags hand-rolled SSRF host guards which reject private/loopback IPv4 ranges but never unwrap IPv6-transition forms (IPv4-mapped ::ffff:, NAT64 64:ff9b::, 6to4 2002::). Such guards can be bypassed by wrapping an internal IPv4 address in a transition literal. Includes a .qhelp with good/bad examples, a change note, and a test pack with two true-positive fixtures (private-ip package guard and a hand-written RFC 1918 denylist) and two negative-control fixtures (ipaddr.js range classifier and an explicit ::ffff: unwrap).

yoff	5fb75ac987	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.
