CVE-2026-5958

In Yealink Plug-in Softwares before 2.35.219.0, an unauthorized file write vulnerability exists under specific scenarios. It may be exploited by attackers to achieve remote code execution.

In Linksys E5350 1.0.00.037, the system function in /wizard/apply.cgi mishandles the ping_ip/traceroute_ip argument, resulting in OS command injection. The attack can be launched remotely and the exploit is publicly available.

In Linksys WRT54GL 4.30.18, the system function in apply.cgi (Traceroute Diagnostic component) mishandles the traceroute_ip argument, enabling OS command injection. The attack can be launched remotely and the exploit has been publicly disclosed.

In Linksys WRT54GL 4.30.18, the system function in apply.cgi (Ping Diagnostic component) mishandles the ping_ip argument, causing OS command injection. The attack can be initiated remotely and the exploit has been made public.

In ESP-IDF (Espressif IoT Development Framework) from 5.5.5 until 5.5.6, 6.0.4, and 6.1.1, the esp_tee trap entry saves a caller-controlled register frame through the REE-supplied stack pointer before switching to the trusted TEE stack or validating the pointer. A local unprivileged REE application can direct this machine-mode write into TEE-exclusive memory on ESP32-C5, ESP32-C6, ESP32-C61, and ESP32-H2 devices, breaking the REE/TEE isolation boundary.

In bitcoinjs-lib (JavaScript Bitcoin library for Node.js and browsers) from 2.3.0 until 5.2.1, 6.1.8, and 7.0.2, fastMerkleRoot pads odd Merkle-tree levels by hashing the final node with itself but does not report adjacent duplicate hashes. Validation paths can accept a recomputed root without checking for mutation, allowing a peer to append duplicate transactions while retaining the original Merkle root, block header, and proof of work.

FreeRDP before 3.32.2 has a use-after-free in the client's rdpgfx dynamic virtual channel: a duplicate-name channel with a new ChannelId overwrites the listener's single callback slot, which rdpgfx_on_close frees without clearing. A malicious RDP server can open and close such a channel, then send a PDU on the original channel to crash the client or potentially execute code.

FreeRDP before 3.32.2 has an out-of-bounds write in the proxy because rdp_read_bitmap_cache_v2_capability_set rejects only numCellCaches values above 5, yet the bitmap cache v2 cell array is later accessed at fixed indices 0 through 4. A client connecting to the proxy can declare fewer than five cell caches in its Confirm Active, causing heap corruption, heap data leakage to the backend, or a crash.

The activestorage gem before 8.1.4.1 for Ruby on Rails, when ImageMagick attachment processing occurs, can allow server read and write operations (e.g., reading secret_key_base) because the ImageMagick analyzer runs when a file is attached, and there is not an ImageMagick security policy to block unintended functionality.

An Authentication Bypass by Capture-replay vulnerability in WatchGuard AuthPoint Gateway allows an attacker who has observed a legitimate request between AuthPoint Gateway components to replay it and perform unauthorized administrative actions, including disrupting authentication services.
