An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-22967 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- concrete5/core (Packagist): affected all versions; fixed in 8.5.7\n- concrete5/core (Packagist): affected all versions; fixed in 8.5.7\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-2021-22967/ (Markdown: https://insights.sbomify.com/CVE-2021-22967/index.md)","id":"CVE-2021-22967","markdown":"https://insights.sbomify.com/CVE-2021-22967/index.md","name":"CVE-2021-22967","record":{"aliases":["GHSA-m2v2-8227-59f5"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Concrete CMS","requires_auth":"none","summary":"Unauthenticated users can access restricted files by adding messages to conversations due to missing permission checks in Concrete CMS.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hackerone","cpe":[{"product":"concrete_cms","vendor":"concretecms"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"In Concrete CMS (formerly concrete 5) below 8.5.7, IDOR Allows Unauthenticated User to Access Restricted Files If Allowed to Add Message to a Conversation.To remediate this, a check was added to verify a user has permissions to view files before attaching the files to a message in \"add / edit message”.Concrete CMS security team gave this a CVSS v3.1 score of 4.3 AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:NCredit for discovery Adrian H","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Exposure of sensitive information in concrete5/core","id":"CVE-2021-22967","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":"concretecms:concrete_cms","products":["concretecms:concrete_cms"],"type":"missing_authorization","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"Improper file handling in concrete5/core","id":"CVE-2021-22968"},"packages":[{"ecosystem":"Packagist","fixed":["8.5.7"],"introduced":["0"],"last_affected":[],"package":"concrete5/core","purl":null,"source":"GHSA-m2v2-8227-59f5"},{"ecosystem":"Packagist","fixed":["8.5.7"],"introduced":["0"],"last_affected":[],"package":"concrete5/core","purl":"pkg:composer/concrete5/core","source":"GHSA-m2v2-8227-59f5"}],"prev":{"headline":"Improper Privilege Management in Concrete CMS","id":"CVE-2021-22966"},"products":["https://github.com/concrete5/concrete5"],"published":"2021-11-19","related":[{"cvss_score":9.8,"headline":"Concrete CMS allows unauthorized access because directories can be created with insecure permissions","id":"CVE-2023-48648","kev_date_added":null,"published":"2023-11-17"},{"cvss_score":9.8,"headline":"Code injection in concrete CMS","id":"CVE-2022-21829","kev_date_added":null,"published":"2022-06-24"},{"cvss_score":9.8,"headline":"Server-Side Request Forgery vulnerability in concrete5","id":"CVE-2021-22958","kev_date_added":null,"published":"2021-10-07"},{"cvss_score":9.8,"headline":"Path traversal in n/a","id":"CVE-2021-40098","kev_date_added":null,"published":"2021-09-27"},{"cvss_score":9.4,"headline":"Concrete CMS Vulnerable to Relative Path Traversal","id":"CVE-2026-8134","kev_date_added":null,"published":"2026-05-21"},{"cvss_score":9.1,"headline":"Path traversal in Concrete CMS","id":"CVE-2022-30117","kev_date_added":null,"published":"2022-06-24"},{"cvss_score":9.1,"headline":"Deserialization in n/a","id":"CVE-2021-40102","kev_date_added":null,"published":"2021-09-24"}],"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":"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":"2024-08-03","vendors":["n/a"]},"summary":"Unauthenticated users can access restricted files by adding messages to conversations due to missing permission checks in Concrete CMS.","url":"https://insights.sbomify.com/CVE-2021-22967/"}
