Security researchers found vulnerabilities in Google’s APK package for Python that could be exploited to breach a trust boundary between two AI agents with different privilege levels. Google has since fixed the issues.
The discovered vulnerabilities affected the interaction of two AI agents with different permission levels within the Google APK environment for Python. By exploiting the trust boundary between these agents, it was possible to trigger automation that could potentially compromise the software supply chain. The original report does not provide concrete technical details on the attack flow, affected version numbers, or a CVE ID.
For CISOs, the incident is another example of a growing attack class: agent-to-agent attacks arise wherever multiple autonomous AI systems with different privileges work together and extend trust to one another without that trust being adequately validated. Such vulnerabilities are particularly critical because they don’t just affect individual systems, but can propagate through automated processes into the software supply chain – potentially endangering downstream dependencies and subsequent build or deployment pipelines.
Organizations that deploy AI agents in automated development or build processes should review the trust relationships between individual agent components and ensure that privilege separation is consistently enforced. According to the report, Google has already patched the vulnerabilities; affected organizations should verify whether their environments are running current versions of the Google APK packages for Python.
Google has fixed vulnerabilities in its Python APK that, via a breached trust boundary between two AI agents, enabled attacks on the software supply chain.
