  1. CVE-2026-54555 7.8 Élevée

    rtk-ai rtk

    rtk filters and compresses command outputs before they reach your LLM context. Prior to 0.42.2, the permission splitter did not conservatively split or reject several shell constructs that Bash treats as command execution boundaries or nested execution. As a result, a command beginning with an allowed prefix such as git could hide a second command behind one of these constructs. rtk rewrite returned exit code 0, causing the Claude hook to emit permissionDecision: "allow". The rewritten command still contained the hidden command, so it ran without the user confirmation or denial that the permission rules were intended to enforce. This vulnerability is fixed in 0.42.2.

  2. CVE-2026-54328 7.3 Élevée

    earendil-works pi

    Pi is a minimal terminal coding harness. From 0.74.0 until 0.78.1, Pi versions with temporary npm or git extension package installs used predictable paths under the operating system temporary directory. On Linux-based multi-user systems, a local attacker who can write to the shared temporary directory could prepare the expected package location before another user runs pi with a temporary extension package source. Pi could then load attacker-controlled extension code in the victim user's process. This vulnerability is fixed in 0.78.1.

  3. CVE-2026-49465 7.7 Élevée

    n8n-io n8n · N8n n8n

    n8n is an open source workflow automation platform. Prior to 1.123.48, 2.21.8, and 2.22.4, an authenticated user with permission to create or modify workflows could supply a local filesystem path as the source repository in the Git node's Clone operation, or as the target repository in the Push operation, bypassing the N8N_RESTRICT_FILE_ACCESS_TO file sandbox. This allowed the contents of any local git repository accessible to the n8n process to be cloned into an allowed path and read, circumventing the access restrictions that correctly blocked direct file reads to the same paths. This vulnerability is fixed in 1.123.48, 2.21.8, and 2.22.4.

  4. CVE-2026-44790 8.8 Élevée

    n8n-io n8n · N8n n8n

    n8n is an open source workflow automation platform. Prior to 1.123.43, 2.22.1, and 2.20.7, an authenticated user with permission to create or modify workflows could inject CLI flags on the Git node's Push operation allowing an attacker to read arbitrary files from the n8n server potentially leading to full compromise. This vulnerability is fixed in 1.123.43, 2.22.1, and 2.20.7.

  5. CVE-2026-35019 8.1 Élevée

    NetComm Wireless Pty Ltd NF20MESH

    NetComm NF20MESH routers running firmware R6B031 and earlier contain an authentication bypass vulnerability that allows unauthenticated attackers to gain administrative access by exploiting a hardcoded AES-256 key used to encrypt session cookies for the web management interface. Attackers can forge a valid encrypted session cookie using the shared hardcoded key and bypass authentication checks to obtain full administrative control of the management interface while any legitimate administrator session is active.
