There are currently no details on how the vulnerability is being weaponized in real-world cyber attacks and the identity of the threat actors that may be exploiting it.

However, the Swiss-headquartered company acknowledged reports of active exploitation in an updated advisory last week. "This vulnerability is known to be exploited in the wild," it said.
