An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2020-13654 exists.\n\nAffected packages and fixed versions:\n- org.xwiki.platform:xwiki-platform-web (Maven): affected all versions; fixed in 12.8\n- org.xwiki.platform:xwiki-platform-web (Maven): affected all versions; fixed in 12.8\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-2020-13654/ (Markdown: https://insights.sbomify.com/CVE-2020-13654/index.md)","id":"CVE-2020-13654","markdown":"https://insights.sbomify.com/CVE-2020-13654/index.md","name":"CVE-2020-13654","record":{"aliases":["GHSA-p93c-h8qm-7256"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"XWiki Platform","requires_auth":"none","summary":"Attackers can execute arbitrary scripts via improper escaping in the property displayer, potentially compromising user sessions.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"xwiki","vendor":"xwiki"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","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-116","name":"Improper Encoding or Escaping of Output"}],"description":"XWiki Platform before 12.8 mishandles escaping in the property displayer.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":"2026-03-30","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-03-30T17:03:59Z","kind":"github_poc","ref":"https://github.com/Astaruf/CVE-2020-13654","stars":0,"title":"CVE-2020-13654 - XWiki Platform \u003c 12.8 - Stored XSS → CSRF → Account Takeover"}],"tier":"weaponised"},"has_fix":true,"headline":"Improper escaping in XWiki Platform","id":"CVE-2020-13654","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"xwiki:xwiki","products":["xwiki:xwiki"],"type":"xss","year":"2020"},"n_packages":2,"n_references":4,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-13655"},"packages":[{"ecosystem":"Maven","fixed":["12.8"],"introduced":["0"],"last_affected":[],"package":"org.xwiki.platform:xwiki-platform-web","purl":null,"source":"GHSA-p93c-h8qm-7256"},{"ecosystem":"Maven","fixed":["12.8"],"introduced":["0"],"last_affected":[],"package":"org.xwiki.platform:xwiki-platform-web","purl":"pkg:maven/org.xwiki.platform/xwiki-platform-web","source":"GHSA-p93c-h8qm-7256"}],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-13653"},"products":["n/a"],"published":"2020-12-31","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":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can execute arbitrary scripts via improper escaping in the property displayer, potentially compromising user sessions.","url":"https://insights.sbomify.com/CVE-2020-13654/"}
