-* Altered 2 patterns in the `poisonable_steps` modelling. Extra sinks are detected in the following cases: scripts executed via python modules and `go run` in directories are detected as potential mechanisms of injection. For the go execution pattern, the pattern is updated to now ignore flags that occur between go and the specific command. This change may lead to more results being detected by the following queries: `actions/untrusted-checkout/high`, `actions/untrusted-checkout/critical`, `actions/untrusted-checkout-toctou/high`, `actions/untrusted-checkout-toctou/critical`, `actions/cache-poisoning/poisonable-step`, `actions/cache-poisoning/direct-cache` and `actions/artifact-poisoning/path-traversal`.

 ## Overview
 
-GitHub workflows can be triggered through various repository events, including incoming pull requests (PRs) or comments on Issues/PRs. Under certain conditions described below, attackers can take over a repository by opening malicious PRs from forks. The attacks can result in malicious code execution causing unauthorized changes to the repository or exfiltration of repository secrets and a compromise of connected systems.
-
-## Workflow Security Model
-
-In GitHub Actions, there is a distinction between unprivileged and privileged workflows. For example, a workflow with a `pull_request` trigger is unprivileged while a workflow with `pull_request_target` is privileged.
-
-This is relevant especially for PRs from forks. Normal PRs can only be submitted by people who have write access to a repository, while PRs from forks can be submitted by anyone.
-
-On a PR from a fork, an unprivileged `pull_request` workflow has only limited capabilities but a privileged `pull_request_target` workflow is much more dangerous. A privileged workflow:
-
-  * Runs in the context of the base repository
-  * Has access to organization and repository secrets (e.g., API keys, deployment tokens)
-  * Has a read/write `GITHUB_TOKEN` by default
-  * Can access private resources
-
-Certain triggers automatically grant a workflow elevated privileges:
-
-  * `pull_request_target` as described above
-  * `workflow_run`: Triggered when another workflow completes.
-  * `issue_comment`: Triggered when a comment is made on an issue or PR.
-
-## Attack Details
-
-  * A repository has a privileged workflow
-  * An attacker forks the repository and adds malicious code (e.g., in the build script)
-  * The attacker opens a PR from the fork, and, if needed, comments on the PR
-  * The workflow in the base repository checks out the forked code
-  * The workflow runs, (e.g. the build script etc.), which contains the malicious code
-
-Please note that not only build scripts can be malicious code vectors. There is a large number of other possibilities. Some of them are listed in the [LOTP](https://boostsecurityio.github.io/lotp/) catalog.
+GitHub workflows can be triggered through various repository events, including incoming pull requests (PRs) or comments on Issues/PRs. A potentially dangerous misuse of the triggers such as `pull_request_target` or `issue_comment` followed by an explicit checkout of untrusted code (Pull Request HEAD) may lead to repository compromise if untrusted code gets executed (e.g., due to a modified build script) in a privileged job.

-## 10.1.0
-
-### New Features
-
-* A new predicate `getSwitchCase` was added to the `SwitchStmt` class, which yields the `n`th `case` statement from a `switch` statement.
-* Data flow barriers and barrier guards can now be added using data extensions. For more information see [Customizing library models for C and C++](https://codeql.github.com/docs/codeql-language-guides/customizing-library-models-for-cpp/).
-
-### Minor Analysis Improvements
-
-* Added taint flow models for the `Strsafe.h` header from the Windows SDK.
-
-## 10.0.0
-
-### Breaking Changes
-
-* The deprecated `NonThrowingFunction` class has been removed, use `NonCppThrowingFunction` instead.
-* The deprecated `ThrowingFunction` class has been removed, use `AlwaysSehThrowingFunction` instead.
-
-### New Features
-
-* Added a subclass `AutoconfConfigureTestFile` of `ConfigurationTestFile` that represents files created by GNU autoconf configure scripts to test the build configuration.

-### Minor Analysis Improvements
-
-* Added `AllocationFunction` models for `aligned_alloc`, `std::aligned_alloc`, and `bsl::aligned_alloc`.
-* The "Comparison of narrow type with wide type in loop condition" (`cpp/comparison-with-wider-type`) query has been upgraded to `high` precision. This query will now run in the default code scanning suite.
-* The "Multiplication result converted to larger type" (`cpp/integer-multiplication-cast-to-long`) query has been upgraded to `high` precision. This query will now run in the default code scanning suite.
-* The "Suspicious add with sizeof" (`cpp/suspicious-add-sizeof`) query has been upgraded to `high` precision. This query will now run in the default code scanning suite.
-* The "Wrong type of arguments to formatting function" (`cpp/wrong-type-format-argument`) query has been upgraded to `high` precision. This query will now run in the default code scanning suite.
-* The "Implicit function declaration" (`cpp/implicit-function-declaration`) query has been upgraded to `high` precision. However, for `build-mode: none` databases, it no longer produces any results. The results in this mode were found to be very noisy and fundamentally imprecise.
