InvokeAI Deserialization of Untrusted Data vulnerabilityGHSA-mcrp-whpw-jp68
CRITICALFix: invoke-ai/InvokeAI@ed46aceGHSA-mcrp-whpw-jp68 is a critical-severity (CVSS 9.8) Deserialization of Untrusted Data vulnerability in invokeai. A fix is available for invokeai — see the affected versions and patch details below.
Exploitation Status
Proof-of-concept exploit code exists
- CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- A successful exploit gives an attacker total control of the affected component, not partial access.

Real-World Exposure
invokeaiReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
A remote code execution vulnerability exists in invoke-ai/invokeai versions 5.3.1 through 5.4.2 via the /api/v2/models/install API. The vulnerability arises from unsafe deserialization of model files using torch.load without proper validation. Attackers can exploit this by embedding malicious code in model files, which is executed upon loading. This issue is fixed in version 5.4.3rc2.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for invokeai, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update invokeai to 5.4.3rc2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-mcrp-whpw-jp68 is resolved across your whole dependency graph.
Workarounds
Do not deserialise data from untrusted sources: where the format allows it, restrict deserialisation to an explicit allowlist of expected types, and prefer a data-only format (JSON, Protobuf) over one that can reconstruct arbitrary objects until you can upgrade.
