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-2026-76252 in the wild and no public exploit code.\n\nAffected product: Splunk Splunk. 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-2026-76252/ (Markdown: https://insights.sbomify.com/CVE-2026-76252/index.md)","id":"CVE-2026-76252","markdown":"https://insights.sbomify.com/CVE-2026-76252/index.md","name":"CVE-2026-76252","record":{"aliases":["GHSA-rvpg-4h5m-w25c"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Splunk Enterprise","requires_auth":"none","summary":"An attacker can execute unauthorized JavaScript in a victim's browser via phishing, potentially accessing data and modifying system integrity in Splunk Enterprise.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"splunk","vendor":"splunk"}],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.13, an unauthenticated user who tricks another user into visiting a malicious web page could run unauthorized JavaScript in that user's browser. This could allow for unauthorized access to all relevant data available to that user and actions that affect system integrity. The Cross-Site Scripting (XSS) is possible because Splunk Web does not validate the origin and source of messages received by a page message handler. The vulnerability requires the attacker to phish the affected user by tricking them into initiating a request within their browser. The unauthenticated user should not be able to exploit the vulnerability at will.","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":"Cross-Site Scripting (XSS) through Splunk Web Message Validation in Splunk Enterprise","id":"CVE-2026-76252","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"splunk:splunk","products":["splunk:splunk"],"type":"xss","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege Escalation through Scheduled Search Alert Action Configuration in Splunk Enterprise","id":"CVE-2026-76253"},"packages":[],"prev":{"headline":"Missing Authorization through REST API Endpoints in the Splunk App for Splunk Observability Cloud","id":"CVE-2026-76251"},"products":["Splunk Enterprise"],"published":"2026-08-19","related":[{"cvss_score":9.8,"headline":"Splunk Enterprise Missing Authentication for Critical Function","id":"CVE-2026-20253","kev_date_added":"2026-06-18","published":"2026-06-10"},{"cvss_score":9.8,"headline":"Missing Authentication for Critical Function in the Patroni REST API in Splunk Enterprise","id":"CVE-2026-76268","kev_date_added":null,"published":"2026-10-07"},{"cvss_score":9.8,"headline":"Improper Neutralization in Splunk Enterprise","id":"CVE-2026-76284","kev_date_added":null,"published":"2026-10-07"},{"cvss_score":9.8,"headline":"Improper Adherence to Coding Standards in Splunk Enterprise","id":"CVE-2026-76285","kev_date_added":null,"published":"2026-10-07"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2017-17067","kev_date_added":null,"published":"2017-11-30"},{"cvss_score":9.8,"headline":"Information disclosure in n/a","id":"CVE-2016-10126","kev_date_added":null,"published":"2017-01-10"},{"cvss_score":9.4,"headline":"Improper Access Control through Embedded Report REST API Requests in Splunk Enterprise","id":"CVE-2026-76310","kev_date_added":null,"published":"2026-08-19"}],"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":"total"},"state":"PUBLISHED","updated":"2026-08-26","vendors":["Splunk"]},"summary":"An attacker can execute unauthorized JavaScript in a victim's browser via phishing, potentially accessing data and modifying system integrity in Splunk Enterprise.","url":"https://insights.sbomify.com/CVE-2026-76252/"}
