Machine-written summary

Summary written by Claude Haiku from the source advisory. 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.
