Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2021-25991 exists.\n\nAffected product: ifmeorg ifme. 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-2021-25991/ (Markdown: https://insights.sbomify.com/CVE-2021-25991/index.md)","id":"CVE-2021-25991","markdown":"https://insights.sbomify.com/CVE-2021-25991/index.md","name":"CVE-2021-25991","record":{"aliases":["GHSA-9869-mhm7-vvmm"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"ifme web application","requires_auth":"low_privilege","summary":"An improper access control flaw allows administrators to ban themselves, resulting in complete loss of admin access to the ifme application.","user_interaction":"required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Mend","cpe":[{"product":"ifme","vendor":"if-me"}],"cvss":{"score":5.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"In Ifme, versions v5.0.0 to v7.32 are vulnerable against an improper access control, which makes it possible for admins to ban themselves leading to their deactivation from Ifme account and complete loss of admin access to Ifme.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"ifme - Improper Access Control leads to admin deactivation","id":"CVE-2021-25991","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"ifme - Insufficient Session Expiration","id":"CVE-2021-25992"},"packages":[],"prev":{"headline":"ifme - Stored Cross-Site Scripting (XSS) in Contacts section","id":"CVE-2021-25990"},"products":["ifme"],"published":"2021-12-29","related":[{"cvss_score":9.8,"headline":"ifme - Insufficient Session Expiration","id":"CVE-2021-25992","kev_date_added":null,"published":"2022-02-10"},{"cvss_score":5.4,"headline":"ifme - Stored Cross-Site Scripting (XSS) in Notifications section","id":"CVE-2021-25988","kev_date_added":null,"published":"2021-12-29"},{"cvss_score":5.4,"headline":"ifme - Stored Cross-Site Scripting (XSS) in Groups section","id":"CVE-2021-25989","kev_date_added":null,"published":"2021-12-29"},{"cvss_score":5.4,"headline":"ifme - Stored Cross-Site Scripting (XSS) in Contacts section","id":"CVE-2021-25990","kev_date_added":null,"published":"2021-12-29"}],"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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-30","vendors":["ifmeorg"]},"summary":"An improper access control flaw allows administrators to ban themselves, resulting in complete loss of admin access to the ifme application.","url":"https://insights.sbomify.com/CVE-2021-25991/"}
