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-2026-0266 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- internment (crates.io): affected from 0.8.7-0; 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-2026-0266/ (Markdown: https://insights.sbomify.com/RUSTSEC-2026-0266/index.md)","id":"RUSTSEC-2026-0266","markdown":"https://insights.sbomify.com/RUSTSEC-2026-0266/index.md","name":"RUSTSEC-2026-0266","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Rust crate","requires_auth":"none","summary":"A malicious dependency in the internment crate allowed arbitrary code execution during build, requiring users to upgrade to a safe version.","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":"A new version of the `internment` crate was published with a direct dependency\non `proc-macro1`, which would execute a malicious build script.\n\nThe compromised version of this crate was published on 2026-08-20, and was\nremoved approximately 90 minutes later.\n\nThe compromised version was used as part of a malware campaign targeted at\nusers of `arrayref`, which was downloaded 2,285 times before being removed; see\n[the `arrayref` advisory][arrayref-advisory] for more detail.\n\n[arrayref-advisory]: https://rustsec.org/advisories/RUSTSEC-2026-0260.html","ecosystems":["crates.io"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"`internment` 0.8.7 was removed from crates.io due to a malicious dependency","id":"RUSTSEC-2026-0266","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"supply_chain","year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"crates.io","fixed":[],"introduced":["0.8.7-0"],"last_affected":[],"package":"internment","purl":"pkg:cargo/internment","source":"RUSTSEC-2026-0266"}],"products":null,"published":"2026-08-20","related":[],"sources":[{"class":"open","licence":"CC0 1.0","name":"RustSec","prefix":"RUSTSEC"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"A malicious dependency in the internment crate allowed arbitrary code execution during build, requiring users to upgrade to a safe version.","url":"https://insights.sbomify.com/RUSTSEC-2026-0266/"}
