CVSS 8.3
CVE-2022-24883 WRITEUP HIGH WRITEUP
FreeRDP < 2.7.0 - Improper Authentication via Invalid SAM File Path
FreeRDP is a free implementation of the Remote Desktop Protocol (RDP). Prior to version 2.7.0, server side authentication against a `SAM` file might be successful for invalid credentials if the server has configured an invalid `SAM` file path. FreeRDP based clients are not affected. RDP server implementations using FreeRDP to authenticate against a `SAM` file are affected. Version 2.7.0 contains a fix for this issue. As a workaround, use custom authentication via `HashCallback` and/or ensure the `SAM` database path configured is valid and the application has file handles left.
CVSS 7.4
CVE-2026-24684 WRITEUP HIGH WRITEUP
FreeRDP < 3.22.0 - Use-After-Free in RDPSND Async Playback Thread
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.22.0, the RDPSND async playback thread can process queued PDUs after the channel is closed and internal state is freed, leading to a use after free in rdpsnd_treat_wave. This vulnerability is fixed in 3.22.0.
CVSS 7.5
CVE-2026-27950 WRITEUP HIGH WRITEUP
FreeRDP < 3.23.0 - Use-After-Free in SDL2 Pointer Implementation
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, the fix for the heap-use-after-free described in CVE-2026-24680 is incomplete. While the vulnerable execution flow referenced in the advisory exists in the SDL2 implementation, the fix appears to have been applied only to the SDL3 code path. In the SDL2 implementation, the pointer is not nulled after free. This creates a situation where the advisory suggests the vulnerability is fully resolved, while builds or environments still using SDL2 may retain the vulnerable logic. A complete fix is available in version 3.23.0.
CVSS 7.5
CVE-2020-11042 WRITEUP MEDIUM WRITEUP
FreeRDP >1.1-<2.0.0 - Memory Corruption
In FreeRDP greater than 1.1 and before 2.0.0, there is an out-of-bounds read in update_read_icon_info.

FreeRDP 1.1.0-2.0.0 - Out-of-bounds Read in Bandwidth Measurement Results
In FreeRDP after 1.1 and before 2.0.0, there is an out-of-bounds read in autodetect_recv_bandwidth_measure_results. A malicious server can extract up to 8 bytes of client memory with a manipulated message by providing a short input and reading the measurement result data. This has been patched in 2.0.0.
CVSS 5.5
CVE-2020-11048 WRITEUP LOW WRITEUP
FreeRDP 1.0.0-2.0.0 - Denial of Service via Out-of-bounds Read
