Not reviewed by a person. > Package skillctl, versions before 0.1.3, contains five flaws, including argument injection through a committed config file, path traversal in the --dest option of add, and hardlink-based file exfiltration. An attacker who can get a crafted .skills.toml file or skill content into a project, or control flag values in agent-driven runs, can corrupt sync decisions, wipe arbitrary directories, forge commit trailers, or read local files into a library. Upgrade to skillctl 0.1.3, which validates these inputs. Written 8 Nov 2026. ## Not analysed yet We haven’t published our analysis of this Advisory yet. Once a person has reviewed it, this page will say what’s vulnerable, what has to be true for your app to be affected, and how to check. ## Severity and exploitation No source has published a CVSS score for this record yet. - **CISA KEV:** Not listed. - **EPSS:** No score. ## Timeline - 31 Oct 2026, 15:18 UTC: First seen by agentprime - 31 Oct 2026, 15:18 UTC: [Confirmed by OSV](https://osv.dev/vulnerability/GHSA-74p7-6h78-gw8p) ## Sources - [GitHub Advisory Database: GHSA-74p7-6h78-gw8p](https://github.com/advisories/GHSA-74p7-6h78-gw8p) - [OSV: GHSA-74p7-6h78-gw8p](https://osv.dev/vulnerability/GHSA-74p7-6h78-gw8p) - - - - - Facts on this page come from the GitHub Advisory Database (CC-BY 4.0), OSV and the other sources listed, as published. We don’t reproduce full advisory descriptions, which can contain exploit code. ## Check whether this affects you A Match means an installed version is in the affected range above. Most don’t affect the app; agentprime hasn’t analysed this one yet. - With the agentprime MCP server (), ask your agent to check the project: `check_lockfile` sends a lockfile, `check_packages` a list of installed packages, and both return the Matches and the upgrades that clear them. `get_advisory` returns this record. Setup: - In a browser: reads your lockfile in the browser, never uploading it. - Whether it touches your code, with file and line: the Claude Code plugin, - As JSON: , or `POST https://api.agentprime.io/v1/match` with your packages () --- The web page: .
