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-2022-31166 exists.\n\nAffected packages and fixed versions:\n- org.xwiki.platform:xwiki-platform-oldcore (Maven): affected from 11.3.7; fixed in 13.10.4\n- org.xwiki.platform:xwiki-platform-oldcore (Maven): affected from 11.3.7; fixed in 13.10.4\n- org.xwiki.platform:xwiki-platform-oldcore (Maven): affected from 14.0-rc-1; fixed in 14.2-rc-1\n- org.xwiki.platform:xwiki-platform-oldcore (Maven): affected from 14.0-rc-1; fixed in 14.2-rc-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-2022-31166/ (Markdown: https://insights.sbomify.com/CVE-2022-31166/index.md)","id":"CVE-2022-31166","markdown":"https://insights.sbomify.com/CVE-2022-31166/index.md","name":"CVE-2022-31166","record":{"aliases":["GHSA-g4h6-qp44-wqvx"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"XWiki Platform","requires_auth":"low_privilege","summary":"Attackers can escalate privileges by exploiting a group resolution bug in XWikiRights, allowing unauthorized access to protected resources.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"xwiki","vendor":"xwiki"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"XWiki Platform Old Core is a core package for XWiki Platform, a generic wiki platform. Starting in versions 11.3.7, 11.0.3, and 12.0RC1, it is possible to exploit a bug in XWikiRights resolution of groups to obtain privilege escalation. More specifically, editing a right with the object editor leads to adding a supplementary empty value to groups which is then resolved as a reference to XWiki.WebHome page. Adding an XWikiGroup xobject to that page then transforms it to a group, any user put in that group would then obtain the privileges related to the edited right. Note that this security issue is normally mitigated by the fact that XWiki.WebHome (and XWiki space in general) should be protected by default for edit rights. The problem has been patched in XWiki 13.10.4 and 14.2RC1 to not consider anymore empty values in XWikiRights. It's possible to work around the problem by setting appropriate rights on XWiki.WebHome page to prevent users to edit it.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"XWiki.WebHome vulnerable to Improper Privilege Management in XWiki resolving groups","id":"CVE-2022-31166","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"xwiki:xwiki","products":["xwiki:xwiki"],"type":"privilege_escalation","year":"2022"},"n_packages":4,"n_references":4,"next":{"headline":"XWiki Platform Security Parent POM vulnerable to overwriting of security rules of a page with a final page having the same reference","id":"CVE-2022-31167"},"packages":[{"ecosystem":"Maven","fixed":["13.10.4"],"introduced":["11.3.7"],"last_affected":[],"package":"org.xwiki.platform:xwiki-platform-oldcore","purl":null,"source":"GHSA-g4h6-qp44-wqvx"},{"ecosystem":"Maven","fixed":["13.10.4"],"introduced":["11.3.7"],"last_affected":[],"package":"org.xwiki.platform:xwiki-platform-oldcore","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-oldcore","source":"GHSA-g4h6-qp44-wqvx"},{"ecosystem":"Maven","fixed":["14.2-rc-1"],"introduced":["14.0-rc-1"],"last_affected":[],"package":"org.xwiki.platform:xwiki-platform-oldcore","purl":null,"source":"GHSA-g4h6-qp44-wqvx"},{"ecosystem":"Maven","fixed":["14.2-rc-1"],"introduced":["14.0-rc-1"],"last_affected":[],"package":"org.xwiki.platform:xwiki-platform-oldcore","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-oldcore","source":"GHSA-g4h6-qp44-wqvx"}],"prev":{"headline":"Tovy before v0.7.51 vulnerable to users logging in as and impersonating other users","id":"CVE-2022-31164"},"products":["xwiki-platform"],"published":"2022-09-07","related":[{"cvss_score":9.8,"headline":"XWiki Platform Eval Injection","id":"CVE-2025-24893","kev_date_added":"2025-10-30","published":"2025-02-20"},{"cvss_score":10,"headline":"XWiki Rendering is vulnerable to RCE attacks when processing nested macros","id":"CVE-2025-53836","kev_date_added":null,"published":"2025-07-14"},{"cvss_score":10,"headline":"XWiki allows remote code execution through the extension sheet","id":"CVE-2024-55662","kev_date_added":null,"published":"2024-12-12"},{"cvss_score":10,"headline":"XWiki allows remote code execution from account through macro descriptions and XWiki.XWikiSyntaxMacrosList","id":"CVE-2024-55877","kev_date_added":null,"published":"2024-12-12"},{"cvss_score":10,"headline":"XWiki Platform vulnerable to remote code execution from account via SearchSuggestConfigSheet","id":"CVE-2024-37901","kev_date_added":null,"published":"2024-07-31"},{"cvss_score":10,"headline":"XWiki programming rights may be inherited by inclusion","id":"CVE-2024-38369","kev_date_added":null,"published":"2024-06-24"},{"cvss_score":10,"headline":"XWiki Platform: Remote code execution from account via SearchSuggestSourceSheet","id":"CVE-2024-31465","kev_date_added":null,"published":"2024-04-10"}],"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":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-04-22","vendors":["xwiki"]},"summary":"Attackers can escalate privileges by exploiting a group resolution bug in XWikiRights, allowing unauthorized access to protected resources.","url":"https://insights.sbomify.com/CVE-2022-31166/"}
