An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-10856 in the wild and no public exploit code.\n\nAffected product: Misp-Project Misp. 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-2026-10856/ (Markdown: https://insights.sbomify.com/CVE-2026-10856/index.md)","id":"CVE-2026-10856","markdown":"https://insights.sbomify.com/CVE-2026-10856/index.md","name":"CVE-2026-10856","record":{"aliases":["GHSA-rx96-8w86-5hhh"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"MISP threat sharing platform","requires_auth":"high_privilege","summary":"Attackers can craft dashboard buttons that redirect users to external sites, enabling phishing and credential theft in MISP deployments.","user_interaction":"not_required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CIRCL","cpe":[{"product":"misp","vendor":"misp-project"}],"cvss":{"score":5.1,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N/U:Green","version":"4.0"},"cwes":[{"id":"CWE-601","name":"URL Redirection to Untrusted Site"}],"description":"A URL validation flaw in the MISP dashboard button widget allowed a crafted relative-looking URL to be accepted as a local path while being interpreted by browsers as an external URL. The validation rejected URLs containing an explicit scheme, host, or user component, but did not reject paths beginning with a slash followed by a backslash, such as /\\example.com. Some browsers normalize backslashes in URLs as forward slashes, which can turn this into a scheme-relative external navigation target. In addition, the generated href concatenated the reconstructed URL with the original URL, increasing the possibility of unsafe or malformed link generation.\n\nAn attacker able to configure or influence a dashboard button URL could craft a button that appears to point inside the application but redirects users to an attacker-controlled site when clicked. This could be used for phishing, credential theft, or social engineering. The patch fixes the issue by rejecting empty paths and paths starting with /\\, and by emitting only the reconstructed validated URL in the anchor href.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Open redirect in MISP dashboard button widget URL handling","id":"CVE-2026-10856","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"misp-project:misp","products":["misp-project:misp"],"type":"open_redirect","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Reflected XSS in Akinsoft's e-Commerce","id":"CVE-2026-10857"},"packages":[],"prev":{"headline":"MISP Event template importer authorization bypass","id":"CVE-2026-10855"},"products":["misp"],"published":"2026-06-04","related":[{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2024-46918","kev_date_added":null,"published":"2024-09-15"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2024-45509","kev_date_added":null,"published":"2024-09-01"},{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2024-29858","kev_date_added":null,"published":"2024-03-21"},{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2024-29859","kev_date_added":null,"published":"2024-03-21"},{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2024-25674","kev_date_added":null,"published":"2024-02-09"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2024-25675","kev_date_added":null,"published":"2024-02-09"},{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2023-50918","kev_date_added":null,"published":"2023-12-15"}],"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":"partial"},"state":"PUBLISHED","updated":"2026-06-04","vendors":["misp"]},"summary":"Attackers can craft dashboard buttons that redirect users to external sites, enabling phishing and credential theft in MISP deployments.","url":"https://insights.sbomify.com/CVE-2026-10856/"}
