An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-124688 in the wild and no public exploit code.\nExposure: An affected version is only exploitable if your software calls TabStrip, PanelBar or Menu. Many projects that include it are not exposed.\n\nAffected product: Progress Software Kendo UI for jQuery. 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.\n   If an affected version is present, also search the code for calls to TabStrip, PanelBar or Menu and report whether any exist.\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-2026-124688/ (Markdown: https://insights.sbomify.com/CVE-2026-124688/index.md)","id":"CVE-2026-124688","markdown":"https://insights.sbomify.com/CVE-2026-124688/index.md","name":"CVE-2026-124688","record":{"aliases":["GHSA-rhfv-9jwg-f856"],"analysis":{"component_type":"library","exploitable_when_present":false,"fix_type":"upgrade","impacts":["account_takeover","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript UI library","requires_auth":"none","requires_specific_call":true,"summary":"Attackers controlling mapped data can inject event-handler attributes into Kendo UI widgets, running JavaScript in victims' sessions; apps using these widgets should care.","user_interaction":"required","vuln_class":"xss","vulnerable_functions":["TabStrip","PanelBar","Menu"]},"analysis_generated_by":"sbomify/insights-2b-fp8","assigner":"ProgressSoftware","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-80","name":"Improper Neutralization of Script-Related HTML Tags in a Web Page"}],"description":"In Progress® Kendo® UI for jQuery prior to 2026.4.1111 the TabStrip, PanelBar, and Menu widgets support mapping a dataSource field to `spriteCssClass`.
