Vulnerability investigation
The available snapshot does not list this vulnerability in CISA KEV; that is not proof exploitation has not occurred. NVD rates the technical severity medium at CVSS 6.5. These are public vulnerability signals, not proof that a specific environment runs an affected version.

Findings stay bounded to named sources and observable infrastructure.
FreeRDP before 3.29.0 contains a buffer over-disclosure vulnerability in the gateway WebSocket transport (libfreerdp/core/gateway/websocket.c). The client's Pong reply reuses a fixed 1024-byte response stream whose length is not sealed to the actual received Ping payload, so a malicious gateway/WebSocket peer sending a non-empty Ping control frame causes the client to reply with an overlong Pong that discloses bytes beyond the received payload (the peer receives the masking key and can unmask the reply). A zero-length Ping reaches an assertion and terminates the client (denial of service).
The base CVE appears first. Independent evidence is added without blocking the page.
