CVE-2026-18852

A flaw has been found in Linksys E5350 1.0.00.037. This impacts the function save_settings of the file /wizard/apply.cgi of the Setup Wizard component. Manipulating the wizard_router_pwd argument can lead to missing authentication. The attack may be launched remotely, and the exploit has been published and may be used.

Sonatype Nexus Repository 3 Pro does not check the local account status when a user signs in through a configured SAML or OAuth2/OpenID Connect identity provider. A user whose account was disabled or locked by an administrator in Nexus Repository can sign in again with valid identity provider credentials for the same account and then receives a new session with the roles of that account.

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.
