It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-124700 in the wild and no public exploit code.\nExposure: An affected version is exposed as installed. No special setting or call is needed.\n\nAffected product: Progress Software Telerik UI for WinForms. 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-2026-124700/ (Markdown: https://insights.sbomify.com/CVE-2026-124700/index.md)","id":"CVE-2026-124700","markdown":"https://insights.sbomify.com/CVE-2026-124700/index.md","name":"CVE-2026-124700","record":{"aliases":["GHSA-mj6m-6q3p-686m"],"analysis":{"component_type":"library","exploitable_when_present":false,"fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"UI component library","requires_auth":"none","requires_specific_call":false,"summary":"Crafted documents or hyperlinks can launch arbitrary OS protocol handlers via unallowlisted URI schemes in Telerik UI for WinForms.","user_interaction":"required","vuln_class":"open_redirect","vulnerable_functions":[]},"analysis_generated_by":"sbomify/insights-2b-fp8","assigner":"ProgressSoftware","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"In Telerik UI for WinForms, versions prior to 2026.4.1111, an untrusted URL redirection vulnerability exists that allows an attacker to launch arbitrary operating system protocol handlers with attacker-controlled arguments via crafted documents and hyperlinks with a non-allowlisted URI scheme that the user opens.","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":"URL Redirection to Untrusted Site in Progress Telerik UI for WinForms","id":"CVE-2026-124700","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"open_redirect","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Deserialization of Untrusted Data in Progress Telerik UI for WinForms","id":"CVE-2026-124701"},"nickname":null,"packages":[],"prev":{"headline":"Improper Control of Generation of Code in Progress Telerik UI for WinForms","id":"CVE-2026-124699"},"products":["Telerik UI for WinForms"],"published":"2026-11-12","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-11-12","vendors":["Progress Software"]},"summary":"Crafted documents or hyperlinks can launch arbitrary OS protocol handlers via unallowlisted URI schemes in Telerik UI for WinForms.","url":"https://insights.sbomify.com/CVE-2026-124700/"}
