Microsoft APM is an open-source, community-driven dependency manager for AI agents. From 0.5.4 to 0.12.4, two primitive integrators in apm-cli enumerate package files with bare Path.glob() / Path.rglob() calls and read each match with Path.read_text(), transparently following symbolic links. A symlink committed inside a remote APM dependency under .apm/prompts/<x>.prompt.md or .apm/agents/<x>.agent.md is preserved verbatim into apm_modules/ on clone and then dereferenced during integration, with the resolved content written as a regular file into the project's deploy directories. The package content_hash, the pre-deploy SecurityGate scan, and apm audit do not flag this. The deploy roots are not added to the auto-generated .gitignore, so the resulting files are staged by git add by default. This vulnerability is fixed in 0.13.0.

Affected: PyPI: apm

## Summary

Two primitive integrators in `apm-cli` enumerate package files with bare `Path.glob()` / `Path.rglob()` calls and read each match with `Path.read_text()`, transparently following symbolic links.

A symlink committed inside a remote APM dependency under `.apm/prompts/<x>.prompt.md` or `.apm/agents/<x>.agent.md` is preserved verbatim into `apm_modules/` on clone and then dereferenced during integration, with the resolved content written as a regular file into the project's deploy directories.

The package `content_hash`, the pre-deploy `SecurityGate` scan, and `apm audit` do not flag this. The deploy roots are not added to the auto-generated `.gitignore`, so the resulting files are staged by `git add` by default.

This was reproduced via the standard `owner/repo#tag` install flow against a real bare git repository. No `--force` or special flags were used.

## Affected code

### Sinks

- `src/apm_cli/integration/prompt_integrator.py` `PromptIntegrator.find_prompt_files`: `package_path.glob("*.prompt.md")` and `apm_prompts.glob("*.prompt.md")` No symlink filter.

- `src/apm_cli/integration/prompt_integrator.py` `PromptIntegrator.copy_prompt`: `source.read_text("utf-8")`

- `src/apm_cli/integration/agent_integrator.py` `AgentIntegrator.find_agent_files`: `package_path.glob("*.agent.md")`, `apm_agents.rglob("*.agent.md")`, `apm_agents.rglob("*.md")`, `apm_chatmodes.glob("*.chatmode.md")` No symlink filter.
