Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-62255 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- com.liferay:com.liferay.knowledge.base.web (Maven): affected all versions; fixed in 5.0.109\n- com.liferay:com.liferay.knowledge.base.web (Maven): affected all versions; fixed in 5.0.109\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-2025-62255/ (Markdown: https://insights.sbomify.com/CVE-2025-62255/index.md)","id":"CVE-2025-62255","markdown":"https://insights.sbomify.com/CVE-2025-62255/index.md","name":"CVE-2025-62255","record":{"aliases":["GHSA-gccf-r9xp-x8jx"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Liferay Portal","requires_auth":"low_privilege","summary":"Remote attackers can inject arbitrary web script via crafted attachment filenames in the Knowledge Base article editor, requiring user interaction to execute.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Liferay","cpe":[{"product":"digital_experience_platform","vendor":"liferay"},{"product":"liferay_portal","vendor":"liferay"}],"cvss":{"score":2,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:L/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Self Cross-site scripting (XSS) vulnerability on the edit Knowledge Base article page in Liferay Portal 7.4.0 through 7.4.3.101, and older unsupported versions, and Liferay DXP 2023.Q3.1 through 2023.Q3.5, 7.4 GA through update 92, and older unsupported versions  allows remote attackers to inject arbitrary web script or HTML via a crafted payload injected into an attachment's filename.","ecosystems":["Maven"],"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":"Liferay Portal Self Cross-site scripting (XSS) vulnerability on the edit Knowledge Base article page","id":"CVE-2025-62255","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":"liferay:digital_experience_platform","products":["liferay:digital_experience_platform","liferay:liferay_portal"],"type":"xss","year":"2025"},"n_packages":2,"n_references":1,"next":{"headline":"Liferay Portal and DXP do not properly restrict access to OpenAPI","id":"CVE-2025-62256"},"packages":[{"ecosystem":"Maven","fixed":["5.0.109"],"introduced":["0"],"last_affected":[],"package":"com.liferay:com.liferay.knowledge.base.web","purl":null,"source":"GHSA-gccf-r9xp-x8jx"},{"ecosystem":"Maven","fixed":["5.0.109"],"introduced":["0"],"last_affected":[],"package":"com.liferay:com.liferay.knowledge.base.web","purl":"pkg:maven/com.liferay/com.liferay.knowledge.base.web","source":"GHSA-gccf-r9xp-x8jx"}],"prev":{"headline":"Liferay Portal ComboServlet denial of service via large file combination","id":"CVE-2025-62254"},"products":["DXP","Portal"],"published":"2025-10-23","related":[{"cvss_score":9.6,"headline":"Liferay Portal and Liferay DXP Vulnerable to CSRF in the Script Console","id":"CVE-2024-8980","kev_date_added":null,"published":"2024-10-22"},{"cvss_score":9.6,"headline":"Liferay Portal and Liferay DXP vulnerable to reflected Cross-site Scripting","id":"CVE-2023-42496","kev_date_added":null,"published":"2024-02-21"},{"cvss_score":9.6,"headline":"Liferay Portal Language Override edit screen and Liferay DXP vulnerable to reflected Cross-site Scripting","id":"CVE-2023-42498","kev_date_added":null,"published":"2024-02-21"},{"cvss_score":9.6,"headline":"Liferay Portal and Liferay DXP vulnerable to Cross-site Scripting","id":"CVE-2024-25147","kev_date_added":null,"published":"2024-02-21"},{"cvss_score":9.6,"headline":"Liferay Portal Frontend JS module's portlet.js and Liferay DXP vulnerable to Cross-site Scripting","id":"CVE-2024-26269","kev_date_added":null,"published":"2024-02-21"},{"cvss_score":9.6,"headline":"Liferay Portal stored cross-site scripting (XSS) vulnerability","id":"CVE-2024-25145","kev_date_added":null,"published":"2024-02-07"},{"cvss_score":9.6,"headline":"Liferay Portal and Liferay DXP Vulnerable to Reflected XSS via the Export for Translation Page","id":"CVE-2023-42497","kev_date_added":null,"published":"2023-10-17"}],"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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-10-23","vendors":["Liferay"]},"summary":"Remote attackers can inject arbitrary web script via crafted attachment filenames in the Knowledge Base article editor, requiring user interaction to execute.","url":"https://insights.sbomify.com/CVE-2025-62255/"}
