Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-28661 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- silverstripe/graphql (Packagist): affected from 3.0.0; fixed in 3.5.2\n- silverstripe/graphql (Packagist): affected from 3.0.0; fixed in 3.5.2\n- silverstripe (Bitnami): affected from 3.0.0; fixed in 3.4.1\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-2021-28661/ (Markdown: https://insights.sbomify.com/CVE-2021-28661/index.md)","id":"CVE-2021-28661","markdown":"https://insights.sbomify.com/CVE-2021-28661/index.md","name":"CVE-2021-28661","record":{"aliases":["BIT-silverstripe-2021-28661","GHSA-r7rh-g777-g5gx"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"SilverStripe GraphQL Server","requires_auth":"low_privilege","summary":"Attackers can bypass permission checks in SilverStripe GraphQL Server due to a failure to inherit the default permission checker in query subclasses.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"silverstripe","vendor":"silverstripe"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"Default SilverStripe GraphQL Server (aka silverstripe/graphql) 3.x through 3.4.1 permission checker not inherited by query subclass.","ecosystems":["Bitnami","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":"SilverStripe GraphQL Server permission checker not inherited by query subclass.","id":"CVE-2021-28661","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"silverstripe:silverstripe","products":["silverstripe:silverstripe"],"type":"missing_authorization","year":"2021"},"n_packages":3,"n_references":2,"next":{"headline":"Denial of service in n/a","id":"CVE-2021-28662"},"packages":[{"ecosystem":"Bitnami","fixed":["3.4.1"],"introduced":["3.0.0"],"last_affected":[],"package":"silverstripe","purl":"pkg:bitnami/silverstripe","source":"BIT-silverstripe-2021-28661"},{"ecosystem":"Packagist","fixed":["3.5.2"],"introduced":["3.0.0"],"last_affected":[],"package":"silverstripe/graphql","purl":null,"source":"GHSA-r7rh-g777-g5gx"},{"ecosystem":"Packagist","fixed":["3.5.2"],"introduced":["3.0.0"],"last_affected":[],"package":"silverstripe/graphql","purl":"pkg:composer/silverstripe/graphql","source":"GHSA-r7rh-g777-g5gx"}],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2021-28660"},"products":["n/a"],"published":"2021-10-07","related":[{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2007-2321","kev_date_added":null,"published":"2007-04-27"},{"cvss_score":9.8,"headline":"Missing warning can lead to unauthenticated admin access in SilverStripe","id":"CVE-2019-12204","kev_date_added":null,"published":"2019-09-25"},{"cvss_score":9.8,"headline":"Silverstripe Framework SQLi Vulnerability","id":"CVE-2019-5715","kev_date_added":null,"published":"2019-04-11"},{"cvss_score":8.8,"headline":"Silverstripe CSRF Protection Bypass via GraphQL","id":"CVE-2019-12437","kev_date_added":null,"published":"2020-02-19"},{"cvss_score":7.5,"headline":"Silverstripe CMS information disclosure","id":"CVE-2020-6164","kev_date_added":null,"published":"2020-07-15"},{"cvss_score":7.5,"headline":"SilverStripe Folders migrated from 3.x may be unsafe to upload to","id":"CVE-2020-9280","kev_date_added":null,"published":"2020-04-15"},{"cvss_score":7.5,"headline":"SQL injection in n/a","id":"CVE-2011-4960","kev_date_added":null,"published":"2012-09-17"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"Attackers can bypass permission checks in SilverStripe GraphQL Server due to a failure to inherit the default permission checker in query subclasses.","url":"https://insights.sbomify.com/CVE-2021-28661/"}
