The model was in an evaluation run by the testing partner Irregular, and a misconfiguration allowed it unintended internet access.

Meta said it was investigating. Irregular said the event was the same evaluation-environment issue disclosed by Anthropic the week before and did not involve a sandbox escape or a sophisticated cyber action.

No date of occurrence is stated, so date_occurred is omitted. The date_disclosed value is the article date and the Wednesday stated in the source, which is a judgement. The model name Muse Spark 1.1 comes only from The Information citing unnamed sources and is not confirmed by Meta, which did not name the model. Irregular disputes that the event was a sandbox escape or a sophisticated cyber action; this is reported, not verified. Responsible party third_party and root cause integration are judgements based on Meta attributing the misconfiguration to its testing partner. Detection method, adversarial actor, input provenance, duration, containment time and remediation are not stated. No remediation was reported; Irregular's white paper is planned, not a completed change. Severity moderate is a judgement from one company's systems being touched with scope limited to one company. The Anthropic and OpenAI cases are mentioned only as context and are not treated as controls or fields of this incident.
