  1. CVE-2026-65623 8.7 Élevée

    mtrudel bandit

    Inefficient Algorithmic Complexity vulnerability in mtrudel bandit allows unauthenticated remote denial of service via CPU exhaustion during WebSocket fragment reassembly. The size guard 'Elixir.Bandit.WebSocket.Connection':oversize_message?/2 called from handle_frame/3 in lib/bandit/websocket/connection.ex appends each non-final continuation frame to a left-nested iolist and then re-measures the entire accumulated buffer with IO.iodata_length/1 on every frame. Because the buffer grows by one element per frame and is fully re-traversed each time, reassembly work is quadratic (O(n^2)) in the number of continuation frames. The max_fragmented_message_size limit (default 8 MB) bounds total bytes but not frame count, and each frame can carry as little as one payload byte, so an attacker can send millions of tiny continuation frames using modest bandwidth to pin a CPU core for minutes to hours. Many concurrent connections can starve the whole server of CPU, denying service to legitimate users. The WebSocket read timeout does not help, because it is an idle timeout evaluated between reads and cannot preempt the synchronous reassembly work spent inside a single callback. This issue affects bandit: from 1.11.0 before 1.12.1.

  2. CVE-2026-66006 5.3 Moyenne

    treeverse lakeFS · Lakefs lakefs

    lakeFS through 1.83.0, fixed in commit 71a45ee, contains an authentication bypass vulnerability in the /setup_comm_prefs endpoint that allows unauthenticated attackers to overwrite operator metadata including email, name, and company after setup completion. Attackers can POST to this endpoint to modify security update preferences, disable security communications, and trigger falsified telemetry events using the legitimate installation ID.

  3. CVE-2026-16519 7.3 Élevée

    GeoVision Inc. GV-IP Device Utility

    A DLL hijacking vulnerability exists in the GeoVision GV-IP Device Utility desktop application. The application loads one or more dynamic-link libraries (DLLs) from an unsafe search path, allowing a local attacker to place a malicious DLL in a location searched before the legitimate library location.

  4. CVE-2024-58354 9.9 Critique

    calcom cal.diy

    cal.com (calcom repository, later renamed cal.diy) is affected by a repository takeover vulnerability in its GitHub Actions workflows. The workflow pr.yml uses the pull_request_target trigger with the repository's default write permissions and passes them down to check-types.yml. check-types.yml then performs a 'dangerous' checkout of the attacker-submitted pull request code (via the dangerous-git-checkout action) and subsequently executes it (through yarn install and package.json scripts). An attacker can open a pull request whose code runs arbitrary commands with the repository's write-scoped GITHUB_TOKEN, allowing them to push commits, merge or mutate pull requests, add or delete comments, and delete or force-push branches, thereby compromising the repository. The main branch is affected; no patched version is available.
