To determine whether your application is affected by CVE-2023-30623, inspect your project dependencies for Embano1/wip:
inspect dependencies for embano1/wipAnalyze the terminal output to locate any version of Embano1/wip in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2), your application is affected.
Note: Verify declared build manifests and deployed runtime container environments.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection'), where the product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. In Embano1/wip, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"details" : "## Summary\nThe `embano1/wip` action uses the `github.event.pull_request.title` parameter in an insecure way. The title parameter is used in a run statement - resulting in a command injection vulnerability due to string interpolation.\n\n## Details and Impact\nThis vulnerability can be triggered by any user on GitHub. They just need to create a pull request with a commit message containing an exploit. (Note that first-time PR requests will not be run - but the attacker can submit a valid PR before submitting an invalid PR). The commit can be genuine, but the commit message can be malicious. \n\nThis can be used to execute code on the GitHub runners (potentially use it for crypto-mining, and waste your resources) and can be used to exfiltrate any secrets that you use in the CI pipeline (including repository tokens). [Here](https://securitylab.github.com/research/github-actions-untrusted-input/) is a set of blog posts by Github's security team explaining this issue.\n\n## How to update existing workflows\n\nReplace the following line in your workflow using this action with the `v2` branch name or commit pointing to this branch:\n\n```yaml\n uses: embano1/wip@v2\n```\n\nOr using the exact commit:\n\n```yaml\n uses: embano1/wip@c25450f77ed02c20d00b76ee3b33ff43838739a2 # v2\n```",
