An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-21524 in the wild and no public exploit code.\n\nAffected product: Microsoft Azure Data Explorer. 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-2026-21524/ (Markdown: https://insights.sbomify.com/CVE-2026-21524/index.md)","id":"CVE-2026-21524","markdown":"https://insights.sbomify.com/CVE-2026-21524/index.md","name":"CVE-2026-21524","record":{"aliases":["GHSA-f7j2-8vfg-mcwq"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Azure Data Explorer","requires_auth":"none","summary":"An unauthorized attacker can disclose sensitive information over the network in Azure Data Explorer.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"azure_data_explorer","vendor":"microsoft"}],"cvss":{"score":7.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:N/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Exposure of sensitive information to an unauthorized actor in Azure Data Explorer allows an unauthorized attacker to disclose information over a network.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Azure Data Explorer Information Disclosure Vulnerability","id":"CVE-2026-21524","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft Windows NULL Pointer Dereference","id":"CVE-2026-21525"},"packages":[],"prev":{"headline":"GitHub Copilot and Visual Studio Code Remote Code Execution Vulnerability","id":"CVE-2026-21523"},"products":["Azure Data Explorer"],"published":"2026-01-22","related":[{"cvss_score":8.1,"headline":"Azure Data Explorer Spoofing Vulnerability","id":"CVE-2022-23256","kev_date_added":null,"published":"2022-02-09"}],"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":"partial"},"state":"PUBLISHED","updated":"2026-07-30","vendors":["Microsoft"]},"summary":"An unauthorized attacker can disclose sensitive information over the network in Azure Data Explorer.","url":"https://insights.sbomify.com/CVE-2026-21524/"}
