When an AI coding agent runs on untrusted fork input in a job that can write to the repository and nothing checks who triggered it, prompt injection becomes remote code execution and repository takeover under the CI token. grackle finds that exact composition statically, before it merges. It proves fork reachability, author and merge gates, and write capability, and reports only the compositions that are actually exploitable. Findings carry a severity, a confidence, the offending workflow block, a dynamic secure-fix write-up, and control-framework references (CWE, OWASP, MITRE ATT&CK and ATLAS, NIST, CIS). Outputs SARIF, GitLab SAST, CycloneDX SBOM, JUnit, JSON, HTML, Markdown, YAML, CSV, and XML. Releases are Sigstore-signed with SLSA Build Level 3 provenance. ### Package name * grackle --- ### License * Apache-2.0 --- ### Last updated * 4 August 2026 - latest/stable --- ### Websites * [cpeoples.github.io](https://cpeoples.github.io/grackle/ "https://cpeoples.github.io/grackle/") --- ### Contact * [github.com/cpeoples/grackle/issues](https://github.com/cpeoples/grackle/issues "https://github.com/cpeoples/grackle/issues") --- ### Donations * [github.com/sponsors/cpeoples](https://github.com/sponsors/cpeoples "https://github.com/sponsors/cpeoples") --- ### Source code * [github.com/cpeoples/grackle](https://github.com/cpeoples/grackle "https://github.com/cpeoples/grackle") --- ### Report a bug * [github.com/cpeoples/grackle/issues](https://github.com/cpeoples/grackle/issues "https://github.com/cpeoples/grackle/issues") --- ##### Report a Snap Store violation * [Report this Snap](https://snapcraft.io/install/grackle/kubuntu#report-snap-modal) --- ## Enable snaps on Kubuntu and install Grackle Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully. Snaps are discoverable and installable from the [Snap Store](https://snapcraft.io/store), an app store with an audience of millions. ### Enable snapd If you’re running [Kubuntu 16.04 LTS (Xenial Xerus)](https://kubuntu.org/) or later, including [Kubuntu 18.04 LTS (Bionic Beaver)](https://wiki.ubuntu.com/BionicBeaver/ReleaseNotes/Kubuntu) and [Kubuntu 18.10 (Cosmic Cuttlefish)](https://wiki.ubuntu.com/CosmicCuttlefish/ReleaseNotes/Kubuntu), you don’t need to do anything. Snap is already installed and ready to go. Versions of Kubuntu between [14.04 LTS (Trusty Tahr)](https://kubuntu.org/news/kubuntu-14-04-lts) and [15.10 (Wily Werewolf)](https://kubuntu.org/news/kubuntu-15-10) don’t include *snap* by default, but *snap* can be installed from the command line as follows: ``` sudo apt update sudo apt install snapd ``` ### Install Grackle To install Grackle, simply use the following command: ``` sudo snap install grackle ``` ### Other popular snaps… [See more...](https://snapcraft.io/search?categories=featured) [See more in Featured](https://snapcraft.io/search?categories=featured) ### More things to do… #### [Get the snap store](https://snapcraft.io/snap-store) Browse and find snaps from the convenience of your desktop using the snap store snap. #### [Learn more about snaps](https://snapcraft.io/docs) Interested to find out more about snaps?
