Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-41235 exists.\n\nAffected packages and fixed versions:\n- froxlor/froxlor (Packagist): affected from 2.3.6; fixed in 2.3.7\n- froxlor/froxlor (Packagist): affected from 2.3.6; fixed in 2.3.7\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-2026-41235/ (Markdown: https://insights.sbomify.com/CVE-2026-41235/index.md)","id":"CVE-2026-41235","markdown":"https://insights.sbomify.com/CVE-2026-41235/index.md","name":"CVE-2026-41235","record":{"aliases":["GHSA-gcv3-5v9q-fmhh"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Server administration software","requires_auth":"low_privilege","summary":"Authenticated customers can bypass shell restrictions to gain host shell access if shell delegation is enabled and nssextrausers is used.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:P","version":"4.0"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"Froxlor is open source server administration software. Version 2.3.6 lets administrators configure `system.available_shells` as the approved shell list that customers may assign to FTP users. However, the server-side FTP account handlers do not enforce that whitelist when processing add or edit requests. As a result, an authenticated customer with shell delegation enabled can submit an arbitrary shell such as `/bin/bash` even when the panel UI only offers more restricted choices. In deployments that use the default `nssextrausers` integration, the attacker-controlled shell is then propagated into the system account database, leading to real host shell access. Version 2.3.7 fixes the issue.","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Froxlor has an authorization bypass in FTP shell assignment via missing server-side `available_shells` enforcement","id":"CVE-2026-41235","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":2,"n_references":2,"next":{"headline":"Froxlor has privilege escalation in SSH key synchronization via symlinked `authorized_keys` path","id":"CVE-2026-41236"},"packages":[{"ecosystem":"Packagist","fixed":["2.3.7"],"introduced":["2.3.6"],"last_affected":[],"package":"froxlor/froxlor","purl":null,"source":"GHSA-gcv3-5v9q-fmhh"},{"ecosystem":"Packagist","fixed":["2.3.7"],"introduced":["2.3.6"],"last_affected":[],"package":"froxlor/froxlor","purl":"pkg:composer/froxlor/froxlor","source":"GHSA-gcv3-5v9q-fmhh"}],"prev":{"headline":"Froxlor: BIND Zone File Injection via TXT Record Content","id":"CVE-2026-41234"},"products":["froxlor"],"published":"2026-06-04","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"total"},"state":"PUBLISHED","updated":"2026-06-08","vendors":["froxlor"]},"summary":"Authenticated customers can bypass shell restrictions to gain host shell access if shell delegation is enabled and nssextrausers is used.","url":"https://insights.sbomify.com/CVE-2026-41235/"}
