Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-45043 exists.\n\nAffected product: rustfs. No package-level version data is available, so check the vendor advisory linked from the reference page.\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/CVE-2026-45043/ (Markdown: https://insights.sbomify.com/CVE-2026-45043/index.md)","id":"CVE-2026-45043","markdown":"https://insights.sbomify.com/CVE-2026-45043/index.md","name":"CVE-2026-45043","record":{"aliases":["GHSA-566f-q62r-wcr8"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"RustFS object storage","requires_auth":"low_privilege","summary":"Attackers with ImportIAMAction can create backdoor service accounts under root, gaining full administrative access to the RustFS object storage system.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:H/SI:H/SA:N","version":"4.0"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"},{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"RustFS is a distributed object storage system built in Rust. Prior to 1.0.0-beta.2, improper validation in the PUT /rustfs/admin/v3/import-iam endpoint allows a user with ImportIAMAction to create service accounts under arbitrary parent identities, including the root user (minioadmin). The endpoint accepts attacker-controlled parent, claims, accessKey, and secretKey values without enforcing privilege boundaries or sanitization. This enables privilege escalation to full administrative access using a persistent, attacker-defined credential.
