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-2026-76983 in the wild and no public exploit code.\n\nAffected product: Apache Wicket. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-76983/ (Markdown: https://insights.sbomify.com/CVE-2026-76983/index.md)","id":"CVE-2026-76983","markdown":"https://insights.sbomify.com/CVE-2026-76983/index.md","name":"CVE-2026-76983","record":{"aliases":["GHSA-5445-5xcv-f4gr"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Java web framework","requires_auth":"low_privilege","summary":"Attackers can inject malicious scripts via form component labels in Apache Wicket applications, requiring an upgrade to patched versions.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"wicket","vendor":"apache"}],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/U:Amber","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Improper neutralization of input during web page generation in Apache Wicket.\n\nThe \u003cwicket:label\u003e tag is provided by org.apache.wicket.markup.html.form.AutoLabelTextResolver, which is registered by default in every WebApplication. The resolver writes the label it finds into the markup as it is, and reads no escaping setting at all, so markup in a label is rendered as markup.\n\nWhen the label comes from the labelled component's label model, set through FormComponent#setLabel(IModel), it is written to the markup unescaped. An application is affected where the label of a form component holds data an attacker can influence. Wicket cannot determine where a model value comes from, so whether it reaches the page from a request or from storage is a property of the application.\n\nThere is no workaround. Unlike every other rendering path in Wicket, the resolver never consulted the escape-model-strings setting, so an application had no way to ask for the label to be escaped.\n\nThe body of a \u003cwicket:label\u003e tag is markup by design and is not affected; it remains the supported way to place markup in a label.\n\nThis issue affects Apache Wicket: from 8.0.0 through 8.18.0, from 9.0.0 through 9.23.0, from 10.0.0 through 10.10.0. Older, unsupported releases from 1.5.0 onwards are also affected. Users are recommended to upgrade to version 8.19.0, 9.24.0 or 10.11.0, which fix the issue.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Apache Wicket: XSS in AutoLabelTextResolver via FormComponent.setLabel","id":"CVE-2026-76983","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Apache Wicket: XSS in MetaDataHeaderItem via addTagAttribute","id":"CVE-2026-76984"},"packages":[],"prev":{"headline":"Apache Wicket: XSS in Button via its model object","id":"CVE-2026-76982"},"products":["Apache Wicket"],"published":"2026-08-31","related":[{"cvss_score":9.8,"headline":"Apache Wicket: Remote code execution via XSLT injection","id":"CVE-2024-36522","kev_date_added":null,"published":"2024-07-12"},{"cvss_score":9.1,"headline":"Apache Wicket: possible session fixation using AuthenticatedWebSession","id":"CVE-2026-40010","kev_date_added":null,"published":"2026-05-06"},{"cvss_score":9.1,"headline":"Deserialization in n/a","id":"CVE-2016-6793","kev_date_added":null,"published":"2017-07-14"},{"cvss_score":8.8,"headline":"Apache Wicket vulnerable to CSRF attacks","id":"CVE-2016-6806","kev_date_added":null,"published":"2017-10-02"},{"cvss_score":7.5,"headline":"Apache Wicket: Configured file upload limits are not enforced when the multipart request has already been parsed","id":"CVE-2026-71257","kev_date_added":null,"published":"2026-08-31"},{"cvss_score":7.5,"headline":"Apache Wicket: crafted URLs can bypass PackageResourceGuard","id":"CVE-2026-43646","kev_date_added":null,"published":"2026-05-06"},{"cvss_score":7.5,"headline":"DNS proxy and possible amplification attack","id":"CVE-2021-23937","kev_date_added":null,"published":"2021-05-25"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-08-31","vendors":["Apache Software Foundation"]},"summary":"Attackers can inject malicious scripts via form component labels in Apache Wicket applications, requiring an upgrade to patched versions.","url":"https://insights.sbomify.com/CVE-2026-76983/"}
