signalk-server has SSRF via absolute signalk.appIcon URL in the app store icon fetcher

The app store icon code (dist/appstore/icon-probe.js around line 200 and icon-bytes.js around line 138) resolves a plugin's declared signalk.appIcon. Relative paths are pinned to the CDN, but an absolute http(s) URL is used as-is: the server fetches it, follows redirects, and stores any image/* response as the plugin's icon, which is then served to the admin UI.

russh's SSH client is susceptible to unbounded allocations via EXT_INFO packets

All evidence, reproduction steps, and scripts in the report were verified against a real running instance. Nothing is fabricated or synthetic; every verdict is backed by captured output from an actual deployment. Concretely, the evidence comes from executing the real russh v0.64.1 client packet parser (Session::process_packet handling handle_ext_info) in a live client session with attacker-supplied packet bodies in the pre-authentication state; the captured output below is from that real execution. …

russh's SSH agent server is susceptible to unbound allocations via repeated SSH_AGENT_CONSTRAIN_CONFIRM messages

All evidence, reproduction steps, and scripts in the report were verified against a real running instance. Nothing is fabricated or synthetic; every verdict is backed by captured output from an actual deployment. The SSH agent server that ships with russh (russh::keys::agent::server::serve) parses client key-addition requests and, for each SSH_AGENT_CONSTRAIN_CONFIRM (0x02) record it finds, pushes one Constraint::Confirm value into a per-key vector inside an unbounded loop, then stores the resulting pair …

russh: peer-declared zero maximum packet size permanently stalls channel writes (silent AsyncWrite hang)

A peer can advertise maximum packet size = 0 in its channel-open message (CHANNEL_OPEN when attacking a server, CHANNEL_OPEN_CONFIRMATION when attacking a client). russh accepts the value without validation and copies it into the channel write state, where it caps the size of every outgoing data chunk. In the AsyncWrite code path (ChannelTx::poll_writable, used by Channel::data(), Channel::make_writer() and Channel::into_stream()), a cap of 0 makes every write future stay Poll::Pending forever: …

russh: Agent server never calls `Agent::confirm`, so keys added with the confirm constraint (`ssh-add -c`) sign without confirmation

The agent server in russh::keys::agent::server never calls Agent::confirm before signing with a key that was added with the confirm constraint. That constraint is SSH_AGENT_CONSTRAIN_CONFIRM (RFC 9987 §5.2.7.2), which is what ssh-add -c sends. The call was replaced by a hard-coded true in 3e04597 ("Native async traits encore", #455), first released in 0.50.0-beta.12. Every release since, up to and including 0.64.1, signs requests for confirm-constrained keys without asking the Agent implementation. …

Two LiteLLM versions published containing credential harvesting malware

After an API Token exposure from an exploited trivy dependency, two new releases of litellm were uploaded to PyPI containing automatically activated malware, harvesting sensitive credentials and files, and exfiltrating to a remote API. Anyone who has installed and run the project should assume any credentials available to litellm environment may have been exposed, and revoke/rotate thema ccordingly.
