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-2026-0260 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- arrayref (crates.io): affected from 0.3.10-0; 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-2026-0260/ (Markdown: https://insights.sbomify.com/RUSTSEC-2026-0260/index.md)","id":"RUSTSEC-2026-0260","markdown":"https://insights.sbomify.com/RUSTSEC-2026-0260/index.md","name":"RUSTSEC-2026-0260","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Rust library","requires_auth":"none","summary":"A malicious version of the arrayref Rust crate executed arbitrary code during build, requiring developers to ensure they do not use the compromised release.","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 `arrayref` crate was published with a direct dependency\non `proc-macro1`, which would execute a malicious build script.\n\nThis compromised version was published on 2026-08-20 and removed approximately\n86 minutes later.
