An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-33419 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/minio/minio (Go): affected all versions; no fix listed\n- github.com/minio/minio (Go): affected all versions up to 0.0.0-20260212201848-7aac2a2c5b7c; no fix listed\n- github.com/minio/minio (Go): affected all versions up to 0.0.0-20260212201848-7aac2a2c5b7c; 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/CVE-2026-33419/ (Markdown: https://insights.sbomify.com/CVE-2026-33419/index.md)","id":"CVE-2026-33419","markdown":"https://insights.sbomify.com/CVE-2026-33419/index.md","name":"CVE-2026-33419","record":{"aliases":["GHSA-jv87-32hw-hh99","GO-2026-4803","MINI-332m-jx4w-xqgc","MINI-q8w4-wxgw-6h7p"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"MinIO object storage","requires_auth":"none","summary":"Attackers can brute-force LDAP credentials via the STS endpoint to gain unauthorized access to S3 buckets and objects.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"minio","vendor":"minio"}],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-307","name":"Improper Restriction of Excessive Authentication Attempts"},{"id":"CWE-204","name":"Observable Response Discrepancy"}],"description":"MinIO is a high-performance object storage system. Prior to RELEASE.2026-03-17T21-25-16Z, MinIO AIStor's STS (Security Token Service) AssumeRoleWithLDAPIdentity endpoint is vulnerable to LDAP credential brute-forcing due to two combined weaknesses: (1) distinguishable error responses that enable username enumeration, and (2) absence of rate limiting on authentication attempts. An unauthenticated network attacker can enumerate valid LDAP usernames and then perform unlimited password guessing to obtain temporary AWS-style STS credentials, gaining access to the victim's S3 buckets and objects.
