Any signed-in user can exploit it over the network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-21564 and fix it if it is affected.\n\nWhat it is: CVE-2023-21564 is a high-severity cross-site scripting vulnerability in Microsoft Azure DevOps Server 2022, published on 14 Feb 2023. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-21564 in the wild and no public exploit code.\n\nAffected product: Microsoft Azure DevOps Server 2022. 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-2023-21564/ (Markdown: https://insights.sbomify.com/CVE-2023-21564/index.md)","id":"CVE-2023-21564","markdown":"https://insights.sbomify.com/CVE-2023-21564/index.md","name":"CVE-2023-21564","record":{"aliases":["GHSA-fvm6-3mw8-9cq2"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Azure DevOps Server","requires_auth":"low_privilege","summary":"Attackers can inject malicious scripts into Azure DevOps Server, potentially executing code or hijacking user accounts.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"azure_devops_server","vendor":"microsoft"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Azure DevOps Server Cross-Site Scripting Vulnerability","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 DevOps Server Cross-Site Scripting Vulnerability","id":"CVE-2023-21564","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Azure DevOps Server Spoofing Vulnerability","id":"CVE-2023-21565"},"packages":[],"prev":{"headline":"BitLocker Security Feature Bypass Vulnerability","id":"CVE-2023-21563"},"products":["Azure DevOps Server 2022"],"published":"2023-02-14","related":[{"cvss_score":9.8,"headline":"Code injection in Azure DevOps Server","id":"CVE-2019-1306","kev_date_added":null,"published":"2019-09-11"},{"cvss_score":9.8,"headline":"Code injection in Azure DevOps Server","id":"CVE-2019-1072","kev_date_added":null,"published":"2019-07-15"},{"cvss_score":8.8,"headline":"Azure DevOps Server Remote Code Execution Vulnerability","id":"CVE-2023-33136","kev_date_added":null,"published":"2023-09-12"},{"cvss_score":7.6,"headline":"Azure DevOps Server Spoofing Vulnerability","id":"CVE-2024-35266","kev_date_added":null,"published":"2024-07-09"},{"cvss_score":7.6,"headline":"Azure DevOps Server Spoofing Vulnerability","id":"CVE-2024-35267","kev_date_added":null,"published":"2024-07-09"},{"cvss_score":7.5,"headline":"Azure DevOps Server Remote Code Execution Vulnerability","id":"CVE-2024-20667","kev_date_added":null,"published":"2024-02-13"},{"cvss_score":7.5,"headline":"Azure DevOps Server Remote Code Execution Vulnerability","id":"CVE-2023-21553","kev_date_added":null,"published":"2023-02-14"}],"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":"2026-08-19","vendors":["Microsoft"]},"summary":"Attackers can inject malicious scripts into Azure DevOps Server, potentially executing code or hijacking user accounts.","url":"https://insights.sbomify.com/CVE-2023-21564/"}
