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-2026-53561 in the wild and no public exploit code.\n\nAffected product: Apache Hive. 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-2026-53561/ (Markdown: https://insights.sbomify.com/CVE-2026-53561/index.md)","id":"CVE-2026-53561","markdown":"https://insights.sbomify.com/CVE-2026-53561/index.md","name":"CVE-2026-53561","record":{"aliases":["GHSA-g32f-6xhp-3ffw"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache Hive","requires_auth":"none","summary":"Unauthenticated attackers can impersonate any Hive user via forged SAML tokens in HTTP mode, gaining unauthorized access to data.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"hive","vendor":"apache"}],"cvss":{"score":7.4,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-345","name":"Insufficient Verification of Data Authenticity"},{"id":"CWE-305","name":"Authentication Bypass by Primary Weakness"},{"id":"CWE-287","name":"Improper Authentication"}],"description":"An improper authentication vulnerability in HiveServer2 SAML bearer-token validation in Apache Hive 4.0.0 through 4.2.0 (and later unreleased branches) on deployments using HTTP transport with hive.server2.authentication=SAML allows an unauthenticated network attacker to authenticate as an arbitrary Hive user and obtain an authenticated HiveServer2 session via a forged Authorization: Bearer token sent to the /cliservice HTTP endpoint. Users are recommended to upgrade to 4.2.1 version that includes the fix for this issue.\n\nAccess / authorization required: No Hive credentials, SAML IdP login, or knowledge of the server signing secret is required. The attacker only needs network reachability to the HiveServer2 HTTP port (typically /cliservice), directly or through a reverse proxy such as Apache Knox that forwards unauthenticated requests to HS2. The instance must have SAML authentication enabled in HTTP mode. Deployments where Knox handles SSO and HiveServer2 uses LDAP/Kerberos (not native SAML mode) are not affected by this specific issue.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Auth bypass in Apache Hive","id":"CVE-2026-53561","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":4,"next":{"headline":"Local Privilege Escalation","id":"CVE-2026-53562"},"packages":[],"prev":{"headline":"SQLBot: Second-Order SQL Injection via Excel Datasource Leading to Remote Command Execution","id":"CVE-2026-53557"},"products":["Apache Hive"],"published":"2026-08-25","related":[{"cvss_score":9.8,"headline":"Apache Hive: SQL Injection vulnerability in HiveMetaStore partition-name direct-SQL paths","id":"CVE-2026-49845","kev_date_added":null,"published":"2026-08-25"},{"cvss_score":9.8,"headline":"Deserialization of Untrusted Data in Jodd","id":"CVE-2018-21234","kev_date_added":null,"published":"2020-05-21"},{"cvss_score":9.1,"headline":"Apache Hive: SSRF vulnerability in Hive Avro Serde due to Insufficient input validation on avro.schema.url","id":"CVE-2026-55976","kev_date_added":null,"published":"2026-08-25"},{"cvss_score":9.1,"headline":"SQL Injection in hive-jdbc","id":"CVE-2018-1282","kev_date_added":null,"published":"2018-04-05"},{"cvss_score":8.3,"headline":"Apache Hive: Deserialization of untrusted data when fetching partitions from the Metastore","id":"CVE-2022-41137","kev_date_added":null,"published":"2024-12-05"},{"cvss_score":8.3,"headline":"High severity vulnerability that affects org.apache.hive:hive, org.apache.hive:hive-exec, and org.apache.hive:hive-service","id":"CVE-2015-7521","kev_date_added":null,"published":"2016-01-29"},{"cvss_score":8.1,"headline":"Improper Authentication in hive:hive-exec","id":"CVE-2018-11777","kev_date_added":null,"published":"2018-11-08"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-26","vendors":["Apache Software Foundation"]},"summary":"Unauthenticated attackers can impersonate any Hive user via forged SAML tokens in HTTP mode, gaining unauthorized access to data.","url":"https://insights.sbomify.com/CVE-2026-53561/"}
