An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2026-13183 and fix it if it is affected.\n\nWhat it is: CVE-2026-13183 is a high-severity vulnerability in Progress Software Telerik UI for ASP.NET AJAX, published on 22 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-13183 in the wild and no public exploit code.\n\nAffected product: Progress Software Telerik UI for ASP.NET AJAX. 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-2026-13183/ (Markdown: https://insights.sbomify.com/CVE-2026-13183/index.md)","id":"CVE-2026-13183","markdown":"https://insights.sbomify.com/CVE-2026-13183/index.md","name":"CVE-2026-13183","record":{"aliases":["GHSA-c5xq-jjwj-x369"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"ASP.NET AJAX UI library","requires_auth":"none","summary":"Remote attackers can recover protected metadata values via timing differences in RadAsyncUpload, requiring an upgrade to Telerik UI for ASP.NET AJAX.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ProgressSoftware","cpe":[{"product":"telerik_ui_for_asp.net_ajax","vendor":"progress"}],"cvss":{"score":7.5,"severity":"high","source":"cna","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-208","name":"Observable Timing Discrepancy"}],"description":"In Progress® Telerik® UI for AJAX prior to v2026.2.708, RadAsyncUpload upload metadata processing may leak cryptographic validity through measurable timing differences, enabling remote attackers to recover protected metadata values.","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":"RadAsyncUpload Upload Metadata Timing Oracle Vulnerability in Telerik UI for ASP.NET AJAX","id":"CVE-2026-13183","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"RadAsyncUpload Default HMAC Key Fallback Vulnerability in Telerik UI for ASP.NET AJAX","id":"CVE-2026-13184"},"packages":[],"prev":{"headline":"RadAsyncUpload Client-State Decrypt-vs-Parse Oracle Vulnerability in Telerik UI for ASP.NET AJAX","id":"CVE-2026-13182"},"products":["Telerik UI for ASP.NET AJAX"],"published":"2026-07-22","related":[{"cvss_score":9.8,"headline":"Telerik UI for ASP.NET AJAX Insecure Direct Object Reference","id":"CVE-2017-11357","kev_date_added":"2023-01-26","published":"2017-08-23"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2021-28141","kev_date_added":null,"published":"2021-03-11"},{"cvss_score":9.8,"headline":"Path traversal in n/a","id":"CVE-2019-19790","kev_date_added":null,"published":"2019-12-13"},{"cvss_score":8.1,"headline":"RadAsyncUpload AsyncUploadTypeName Type Resolution Vulnerability in Telerik UI for ASP.NET AJAX","id":"CVE-2026-13181","kev_date_added":null,"published":"2026-07-22"},{"cvss_score":8.1,"headline":"PersistenceFramework Cookie Deserialization Vulnerability in Telerik UI for ASP.NET AJAX","id":"CVE-2026-13185","kev_date_added":null,"published":"2026-07-22"},{"cvss_score":8.1,"headline":"AppDataStorageProvider Path Traversal Deserialization Vulnerability in Telerik UI for ASP.NET AJAX","id":"CVE-2026-13186","kev_date_added":null,"published":"2026-07-22"},{"cvss_score":8.1,"headline":"DialogHandler Provider Type Tampering Vulnerability in Telerik UI for ASP.NET AJAX","id":"CVE-2026-13187","kev_date_added":null,"published":"2026-07-22"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-07-22","vendors":["Progress Software"]},"summary":"Remote attackers can recover protected metadata values via timing differences in RadAsyncUpload, requiring an upgrade to Telerik UI for ASP.NET AJAX.","url":"https://insights.sbomify.com/CVE-2026-13183/"}
