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-2026-15639 in the wild and no public exploit code.\n\nAffected product: Delinea Secret Server (On-Prem). 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-2026-15639/ (Markdown: https://insights.sbomify.com/CVE-2026-15639/index.md)","id":"CVE-2026-15639","markdown":"https://insights.sbomify.com/CVE-2026-15639/index.md","name":"CVE-2026-15639","record":{"aliases":["GHSA-5jwp-q2ph-6mgc"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Secret Server","requires_auth":"none","summary":"Attackers can execute arbitrary JavaScript in victims' browsers via crafted links, potentially leading to session hijacking or data theft in Delinea Secret Server.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Delinea","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:N/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"An attacker can craft a malicious link that, if used by a legitimate user, may cause the user's browser to run JavaScript supplied by the attacker.","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":"Reflected Cross-Site Scripting","id":"CVE-2026-15639","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Authentication Bypass via SAML Response Manipulation","id":"CVE-2026-15640"},"packages":[],"prev":{"headline":"Cryptographic Padding Oracle","id":"CVE-2026-15638"},"products":["Secret Server (On-Prem)"],"published":"2026-09-15","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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-16","vendors":["Delinea"]},"summary":"Attackers can execute arbitrary JavaScript in victims' browsers via crafted links, potentially leading to session hijacking or data theft in Delinea Secret Server.","url":"https://insights.sbomify.com/CVE-2026-15639/"}
