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-2023-29201 exists.\n\nAffected packages and fixed versions:\n- org.xwiki.commons:xwiki-commons-xml (Maven): affected from 4.2-milestone-1; fixed in 14.6-rc-1\n- org.xwiki.commons:xwiki-commons-xml (Maven): affected from 4.2-milestone-1; fixed in 14.6-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-2023-29201/ (Markdown: https://insights.sbomify.com/CVE-2023-29201/index.md)","id":"CVE-2023-29201","markdown":"https://insights.sbomify.com/CVE-2023-29201/index.md","name":"CVE-2023-29201","record":{"aliases":["GHSA-m3jr-cvhj-f35j"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"XWiki Commons library","requires_auth":"low_privilege","summary":"Insufficient HTML sanitization in restricted mode allows XSS, enabling server-side code execution when privileged users view malicious comments.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"xwiki","vendor":"xwiki"}],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"XWiki Commons are technical libraries common to several other top level XWiki projects. The \"restricted\" mode of the HTML cleaner in XWiki, introduced in version 4.2-milestone-1, only escaped `\u003cscript\u003e` and `\u003cstyle\u003e`-tags but neither attributes that can be used to inject scripts nor other dangerous HTML tags like `\u003ciframe\u003e`. As a consequence, any code relying on this \"restricted\" mode for security is vulnerable to JavaScript injection (\"cross-site scripting\"/XSS). When a privileged user with programming rights visits such a comment in XWiki, the malicious JavaScript code is executed in the context of the user session. This allows server-side code execution with programming rights, impacting the confidentiality, integrity and availability of the XWiki instance. This problem has been patched in XWiki 14.6 RC1 with the introduction of a filter with allowed HTML elements and attributes that is enabled in restricted mode. There are no known workarounds apart from upgrading to a version including the fix.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":"2025-08-20","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-08-20T10:33:09Z","kind":"github_poc","ref":"https://github.com/shoucheng3/xwiki__xwiki-commons_CVE-2023-29201_14-5","stars":0,"title":null}],"tier":"weaponised"},"has_fix":true,"headline":"org.xwiki.commons:xwiki-commons-xml Cross-site Scripting vulnerability","id":"CVE-2023-29201","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"xwiki:xwiki","products":["xwiki:xwiki"],"type":"xss","year":"2023"},"n_packages":2,"n_references":6,"next":{"headline":"org.xwiki.platform:xwiki-platform-rendering-macro-rss Cross-site Scripting vulnerability","id":"CVE-2023-29202"},"packages":[{"ecosystem":"Maven","fixed":["14.6-rc-1"],"introduced":["4.2-milestone-1"],"last_affected":[],"package":"org.xwiki.commons:xwiki-commons-xml","purl":null,"source":"GHSA-m3jr-cvhj-f35j"},{"ecosystem":"Maven","fixed":["14.6-rc-1"],"introduced":["4.2-milestone-1"],"last_affected":[],"package":"org.xwiki.commons:xwiki-commons-xml","purl":"pkg:maven/org.xwiki.commons/xwiki-commons-xml","source":"GHSA-m3jr-cvhj-f35j"}],"prev":{"headline":"contao/core-bundle has path traversal vulnerability in the file manager","id":"CVE-2023-29200"},"products":["xwiki-commons"],"published":"2023-04-15","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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-02-06","vendors":["xwiki"]},"summary":"Insufficient HTML sanitization in restricted mode allows XSS, enabling server-side code execution when privileged users view malicious comments.","url":"https://insights.sbomify.com/CVE-2023-29201/"}
