What impact to service availability/management could be caused by implementing the mitigations?
Implementing these mitigations will not impact service availability or management operations.
Do customers need to revert the changes made to mitigate the vulnerability once the security update to protect against this vulnerability is available?
No. The security update will maintain the mitigation's behavior once the security update is installed.
I am using TPM+PIN, am I at risk of this vulnerability being exploited
No, if you are using TPM+PIN the vulnerability is not exploitable.

For example, if your organization\u2019s employees take their work devices home or on business travel.\nWhat impact to service availability/management could be caused by implementing the mitigations?\nImplementing these mitigations will not impact service availability or management operations.\nDo customers need to revert the changes made to mitigate the vulnerability once the security update to protect against this vulnerability is available?\nNo. The security update will maintain the mitigation\u0027s behavior once the security update is installed.\nI am using TPM+PIN, am I at risk of this vulnerability being exploited\nNo, if you are using TPM+PIN the vulnerability is not exploitable."

Title
Microsoft APM: Windows absolute-path tar member overwrite during legacy-bundle probing in `apm install`
Summary
Microsoft APM is an open-source, community-driven dependency manager for AI agents. Prior to 0.13.0, Microsoft APM contains a Windows-specific archive extraction boundary failure in the legacy-bundle probe used by apm install <bundle> on supported Python 3.10 and 3.11 runtimes. When apm install is given a local .tar.gz that is not recognized as a plugin-format bundle, APM probes whether it is a legacy --format apm bundle. On Python versions earlier than 3.12, that probe extracts untrusted tar members with raw tar.extractall() without rejecting Windows absolute member names such as D:/.... This vulnerability is fixed in 0.13.0.

Title
Microsoft APM: Symlinks under `.apm/prompts/` and `.apm/agents/` are dereferenced during `apm install`, copying host-local file contents into the project tree
Summary
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.

Title
Microsoft APM: plugin.json component paths escape plugin root and copy arbitrary host files during install
Summary
Microsoft APM is an open-source, community-driven dependency manager for AI agents. Prior to 0.8.12, Microsoft APM normalizes marketplace plugins by copying plugin components referenced in plugin.json into .apm/. The manifest fields agents, skills, commands, and hooks are attacker-controlled, but the implementation does not enforce that those paths remain inside the plugin directory. A malicious plugin can therefore use absolute paths or ../ traversal paths to copy arbitrary readable host files or directories from the installer's machine during apm install. This vulnerability is fixed in 0.8.12.

Kiota abstractions RedirectHandler leaks Cookie/Proxy-Authorization headers on cross-host redirect
Summary
The RedirectHandler middleware in microsoft/kiota-java (com.microsoft.kiota:microsoft-kiota-http-okHttp v1.9.0) and other Kiota libraries fails to strip sensitive HTTP headers when following 3xx redirects to a different host or scheme. Only the Authorization header is removed; Cookie, Proxy-Authorization, and all custom headers are forwarded to the redirect target.
