An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-73290 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-2026-73290/ (Markdown: https://insights.sbomify.com/CVE-2026-73290/index.md)","id":"CVE-2026-73290","markdown":"https://insights.sbomify.com/CVE-2026-73290/index.md","name":"CVE-2026-73290","record":{"aliases":["GHSA-x298-9x87-fvjq"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"RustFS object storage","requires_auth":"none","summary":"Attackers can bypass public access restrictions to list object versions in RustFS buckets, exposing metadata despite configured deny rules.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"RustFS is a distributed object storage system built in Rust. Prior to 1.0.0-beta.12, an anonymous ListObjectVersions request in rustfs/src/storage/access.rs that lacks a direct bucket-policy grant falls back to an s3:ListBucket check and returns before the policy_allowed path applies deny_anonymous_table_data_plane_if_needed and RestrictPublicBuckets, so a bucket that permits anonymous listing can continue exposing version listings after an operator enables the public-access control.
