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-2025-53835 exists.\n\nAffected packages and fixed versions:\n- org.xwiki.rendering:xwiki-rendering-syntax-xhtml (Maven): affected from 5.4.5; fixed in 14.10\n- org.xwiki.rendering:xwiki-rendering-syntax-xhtml (Maven): affected from 5.4.5; fixed in 14.10\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-2025-53835/ (Markdown: https://insights.sbomify.com/CVE-2025-53835/index.md)","id":"CVE-2025-53835","markdown":"https://insights.sbomify.com/CVE-2025-53835/index.md","name":"CVE-2025-53835","record":{"aliases":["GHSA-w3wh-g4m9-783p"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"XWiki rendering system","requires_auth":"low_privilege","summary":"Attackers can inject arbitrary JavaScript via XHTML syntax in editable documents, leading to XSS and potential account takeover.","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-80","name":"Improper Neutralization of Script-Related HTML Tags in a Web Page"},{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"XWiki Rendering is a generic rendering system that converts textual input in a given syntax (wiki syntax, HTML, etc) into another syntax (XHTML, etc). Starting in version 5.4.5 and prior to version 14.10, the XHTML syntax depended on the `xdom+xml/current` syntax which allows the creation of raw blocks that permit the insertion of arbitrary HTML content including JavaScript. This allows XSS attacks for users who can edit a document like their user profile (enabled by default). This has been fixed in version 14.10 by removing the dependency on the `xdom+xml/current` syntax from the XHTML syntax. Note that the `xdom+xml` syntax is still vulnerable to this attack. As it's main purpose is testing and its use is quite difficult, this syntax shouldn't be installed or used on a regular wiki. There are no known workarounds apart from upgrading.","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 Rendering is vulnerable to XSS attacks through insecure XHTML syntax","id":"CVE-2025-53835","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"xwiki:xwiki","products":["xwiki:xwiki"],"type":"xss","year":"2025"},"n_packages":2,"n_references":3,"next":{"headline":"XWiki Rendering is vulnerable to RCE attacks when processing nested macros","id":"CVE-2025-53836"},"packages":[{"ecosystem":"Maven","fixed":["14.10"],"introduced":["5.4.5"],"last_affected":[],"package":"org.xwiki.rendering:xwiki-rendering-syntax-xhtml","purl":null,"source":"GHSA-w3wh-g4m9-783p"},{"ecosystem":"Maven","fixed":["14.10"],"introduced":["5.4.5"],"last_affected":[],"package":"org.xwiki.rendering:xwiki-rendering-syntax-xhtml","purl":"pkg:maven/org.xwiki.rendering/xwiki-rendering-syntax-xhtml","source":"GHSA-w3wh-g4m9-783p"}],"prev":{"headline":"Caido Toast Vulnerable to Reflected Cross-site Scripting","id":"CVE-2025-53834"},"products":["xwiki-rendering"],"published":"2025-07-14","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":"2025-07-15","vendors":["xwiki"]},"summary":"Attackers can inject arbitrary JavaScript via XHTML syntax in editable documents, leading to XSS and potential account takeover.","url":"https://insights.sbomify.com/CVE-2025-53835/"}
