An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of RUSTSEC-2026-0016 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- polymarkets-rs-clob-client (crates.io): affected from 0.0.0-0; no fix listed\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/RUSTSEC-2026-0016/ (Markdown: https://insights.sbomify.com/RUSTSEC-2026-0016/index.md)","id":"RUSTSEC-2026-0016","markdown":"https://insights.sbomify.com/RUSTSEC-2026-0016/index.md","name":"RUSTSEC-2026-0016","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"no_fix_stated","impacts":["data_read","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Rust crate","requires_auth":"none","summary":"A malicious Rust crate was published to steal Polymarket credentials via typosquatting, requiring developers to audit dependencies.","user_interaction":"not_required","vuln_class":"supply_chain"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"This is part of an ongoing campaign to attempt to typosquat crates in the\n[`polymarket-client-sdk`](https://crates.io/crates/polymarket-client-sdk)\necosystem to exfiltrate user credentials.\n\nThe malicious crate had 1 version published on 2026-02-19 approximately 20\nhours before removal and had no evidence of actual downloads.
