In versions of the Datadog Android application prior to v541-5.9.2, BubbleChatActivity is exported with no permission guard and accepts a SEND intent with a caller-supplied conversation_id. When the activity closes and no in-process session matches that ID, it unconditionally cancels notification ID 9201 (the Bits AI chat notification), with no check on the caller's identity or ownership of the conversation. This requires a malicious application co-installed on the victim's device. Impact: A co-installed application can silently dismiss the victim's Bits AI chat notification. No chat content is exposed; conversation data remains server-authentication gated and is never returned to the caller.
