DescriptionCVE.org

KanaDojo before 0.1.18 contains a sandbox escape vulnerability that allows an attacker to execute arbitrary code by exploiting the explicit passing of the global require function into a Node.js vm.runInNewContext() sandbox context in the issue-auto-respond.yml workflow. Attackers can submit a pull request modifying messages.cjs to import arbitrary Node.js modules, bypassing sandbox restrictions and achieving remote code execution with full GitHub Actions runner privileges including access to AUTOMATION_PR_TOKEN.

AnalysisAI

Sandbox escape leading to remote code execution affects KanaDojo (lingdojo/kana-dojo) before version 0.1.18, where the issue-auto-respond.yml GitHub Actions workflow passes the global require function into a Node.js vm.runInNewContext() sandbox. An attacker submitting a pull request that modifies messages.cjs can load arbitrary Node.js modules from within the sandbox and gain code execution on the Actions runner with access to AUTOMATION_PR_TOKEN. …

Vulnerability AssessmentAI

Exploitation Exploitation requires the attacker to be able to submit a pull request that modifies messages.cjs in the lingdojo/kana-dojo repository (or a fork running the vulnerable issue-auto-respond.yml workflow), and the vulnerable workflow must actually evaluate that file using vm.runInNewContext with the global require function exposed in the sandbox context. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector AV:N/AC:L/AT:N/PR:L/UI:P/VC:H/VI:H/VA:N reflects a network-reachable attack (open a PR) with low complexity, low privileges (a GitHub account that can fork and submit PRs), and passive user interaction (a maintainer triggering or approving the workflow run). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker forks lingdojo/kana-dojo and opens a pull request that modifies messages.cjs to include code such as require('child_process').execSync(...) inside what is intended to be sandboxed logic. When a maintainer interaction or the workflow trigger causes issue-auto-respond.yml to evaluate the file via vm.runInNewContext with require exposed, the payload executes on the GitHub Actions runner and exfiltrates AUTOMATION_PR_TOKEN, which the attacker then uses to push malicious commits or release artifacts.
Remediation Vendor-released patch: upgrade to KanaDojo v0.1.18 or later, which applies the fix in commit 31b85a5d7c4b323ddeba3b2dc5e7807558710544 (https://github.com/lingdojo/kana-dojo/commit/31b85a5d7c4b323ddeba3b2dc5e7807558710544). … Detailed patch versions, workarounds, and compensating controls in full report.
