Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-41372 in the wild and no public exploit code.\n\nAffected product: Microsoft Power BI Report Server version 1.11.8091.10468. 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-2021-41372/ (Markdown: https://insights.sbomify.com/CVE-2021-41372/index.md)","id":"CVE-2021-41372","markdown":"https://insights.sbomify.com/CVE-2021-41372/index.md","name":"CVE-2021-41372","record":{"aliases":["GHSA-3w9m-7j3j-w9p6"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Power BI Report Server","requires_auth":"low_privilege","summary":"Attackers can upload malicious templates to execute scripts and escalate privileges via XSS and CSRF in Power BI Report Server.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"power_bi_report_server","vendor":"microsoft"}],"cvss":{"score":7.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:L/A:N/E:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"},{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"A Cross-Site Scripting (XSS) and Cross-Site Request Forgery (CSRF) vulnerability exists when Power BI Report Server Template file (pbix) containing HTML files is uploaded to the server and HTML files are accessed directly by the victim.\nCombining these 2 vulnerabilities together, an attacker is able to upload malicious Power BI templates files to the server using the victim's session and run scripts in the security context of the user and perform privilege escalation in case the victim has admin privileges when the victim access one of the HTML files present in the malicious Power BI template uploaded.\nThe security update addresses the vulnerability by helping to ensure that Power BI Report Server properly sanitize file uploads.","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":"Power BI Report Server Spoofing Vulnerability","id":"CVE-2021-41372","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"FSLogix Information Disclosure Vulnerability","id":"CVE-2021-41373"},"packages":[],"prev":{"headline":"Windows Remote Desktop Protocol (RDP) Information Disclosure Vulnerability","id":"CVE-2021-41371"},"products":["Power BI Report Server version 1.11.8091.10468","Power BI Report Server version 1.12.7977.29537"],"published":"2021-11-10","related":[{"cvss_score":8.8,"headline":"Power BI Remote Code Execution Vulnerability","id":"CVE-2026-65811","kev_date_added":null,"published":"2026-08-11"},{"cvss_score":8.2,"headline":"Power BI Report Server Spoofing Vulnerability","id":"CVE-2023-21806","kev_date_added":null,"published":"2023-02-14"},{"cvss_score":8,"headline":"Microsoft PowerBI Report Server Spoofing Vulnerability","id":"CVE-2026-58647","kev_date_added":null,"published":"2026-07-14"},{"cvss_score":8,"headline":"Power BI Remote Code Execution Vulnerability","id":"CVE-2026-21229","kev_date_added":null,"published":"2026-02-10"},{"cvss_score":7.7,"headline":"Microsoft Power BI Information Disclosure Vulnerability","id":"CVE-2021-26859","kev_date_added":null,"published":"2021-03-11"},{"cvss_score":7.6,"headline":"Power BI Remote Code Execution Vulnerability","id":"CVE-2021-31984","kev_date_added":null,"published":"2021-07-14"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-08-19","vendors":["Microsoft"]},"summary":"Attackers can upload malicious templates to execute scripts and escalate privileges via XSS and CSRF in Power BI Report Server.","url":"https://insights.sbomify.com/CVE-2021-41372/"}
