Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-62506 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/minio/minio (Go): affected all versions; fixed in 0.0.0-20251015170045-c1a49490c78e\n- github.com/minio/minio (Go): affected all versions; fixed in 0.0.0-20251015170045-c1a49490c78e\n- github.com/minio/minio (Go): affected all versions; fixed in 0.0.0-20251015170045-c1a49490c78e\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-2025-62506/ (Markdown: https://insights.sbomify.com/CVE-2025-62506/index.md)","id":"CVE-2025-62506","markdown":"https://insights.sbomify.com/CVE-2025-62506/index.md","name":"CVE-2025-62506","record":{"aliases":["GHSA-jjjj-jwhf-8rgr","GO-2025-4034","MINI-r348-f45c-c4fx","MINI-w975-883j-fg87"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"MinIO object storage","requires_auth":"low_privilege","summary":"Attackers with restricted service or STS credentials can bypass policy restrictions to create unrestricted accounts, gaining unauthorized access to modify or delete data.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"MinIO is a high-performance object storage system. In all versions prior to RELEASE.2025-10-15T17-29-55Z, a privilege escalation vulnerability allows service accounts and STS (Security Token Service) accounts with restricted session policies to bypass their inline policy restrictions when performing operations on their own account, specifically when creating new service accounts for the same user. The vulnerability exists in the IAM policy validation logic where the code incorrectly relied on the DenyOnly argument when validating session policies for restricted accounts. When a session policy is present, the system should validate that the action is allowed by the session policy, not just that it is not denied. An attacker with valid credentials for a restricted service or STS account can create a new service account for itself without policy restrictions, resulting in a new service account with full parent privileges instead of being restricted by the inline policy. This allows the attacker to access buckets and objects beyond their intended restrictions and modify, delete, or create objects outside their authorized scope. The vulnerability is fixed in version RELEASE.2025-10-15T17-29-55Z.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":"2025-10-23","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-10-23T12:18:17Z","kind":"github_poc","ref":"https://github.com/yoshino-s/CVE-2025-62506","stars":0,"title":"Exploit for CVE-2025-62506"}],"tier":"poc_unverified"},"has_fix":true,"headline":"MinIO vulnerable to privilege escalation via session policy bypass in service accounts and STS","id":"CVE-2025-62506","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"privilege_escalation","year":"2025"},"n_packages":3,"n_references":3,"next":{"headline":"Redis: Bug in XACKDEL may lead to stack overflow and potential RCE","id":"CVE-2025-62507"},"packages":[{"ecosystem":"Go","fixed":["0.0.0-20251015170045-c1a49490c78e"],"introduced":["0"],"last_affected":[],"package":"github.com/minio/minio","purl":null,"source":"GHSA-jjjj-jwhf-8rgr"},{"ecosystem":"Go","fixed":["0.0.0-20251015170045-c1a49490c78e"],"introduced":["0"],"last_affected":[],"package":"github.com/minio/minio","purl":"pkg:golang/github.com/minio/minio","source":"GHSA-jjjj-jwhf-8rgr"},{"ecosystem":"Go","fixed":["0.0.0-20251015170045-c1a49490c78e"],"introduced":["0"],"last_affected":[],"package":"github.com/minio/minio","purl":"pkg:golang/github.com/minio/minio","source":"GO-2025-4034"}],"prev":{"headline":"SSRF in lobehub/lobe-chat with native web fetch module","id":"CVE-2025-62505"},"products":["minio"],"published":"2025-10-16","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-10-23","vendors":["minio"]},"summary":"Attackers with restricted service or STS credentials can bypass policy restrictions to create unrestricted accounts, gaining unauthorized access to modify or delete data.","url":"https://insights.sbomify.com/CVE-2025-62506/"}
