Google, JPMorgan and others patch same class of MCP server flaw

On October 6, 2026, The Next Web reported that Google, JPMorgan Chase, Weaviate, France's interministerial digital directorate (DINUM) and the city government of Tangerang in Indonesia have each fixed the same type of flaw in their Model Context Protocol (MCP) servers. According to the report, all five issues were discovered and reported by independent researcher Syed Anas Mohiuddin, who said in an update published this month that he had reported every one of them. The Next Web describes MCP as a standard; the available excerpt of the story cuts off at that point.

The report does not say when the flaws were found, how they could have been exploited, which systems or data were affected, or when each organization finished its fix. It also does not indicate whether the five cases are technically linked to one another. Apart from Mohiuddin's own account, none of the five organizations is quoted giving its own description of the flaw or of the remediation work. As of the report, the situation stands at the point where all five parties have completed their fixes, and no further claims about the nature, cause or wider reach of the flaw appear in the material.
