Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-85226 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-2026-85226/ (Markdown: https://insights.sbomify.com/CVE-2026-85226/index.md)","id":"CVE-2026-85226","markdown":"https://insights.sbomify.com/CVE-2026-85226/index.md","name":"CVE-2026-85226","record":{"aliases":["GHSA-x79g-96j5-8jrv"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"MISP threat sharing platform","requires_auth":"low_privilege","summary":"Authenticated users can view restricted correlation data due to missing access control checks in the OnDemand correlation engine.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CIRCL","cpe":[{"product":"misp","vendor":"misp-project"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"MISP contains an authorization flaw in the OnDemand correlation engine where correlations were calculated solely from matching attribute values without applying the distribution, sharing group, organization, or other access-control restrictions associated with the correlated attributes and events. As a result, an authenticated user could receive correlation results referring to attributes or events that the user was not authorized to access. \n\nThe vulnerable correlation collection path did not take the requesting user into account. The patch changes the correlation collector to accept the current user and filters the resulting attribute identifiers through MISP's existing fetchAttributesSimple() authorization logic, which evaluates event-, attribute-, object-, distribution-, and sharing-group-level restrictions against the live data.  \n\nThe issue also affected paths relying on previously stored correlation data. Because the OnDemand engine does not maintain the stored correlation table, its denormalized access-control information could be stale. The patch therefore validates correlated attribute identifiers against the current ACLs before returning them and additionally applies normal event visibility conditions when retrieving related events.  \n\nAn authenticated low-privileged user could exploit this issue by querying or creating attributes that correlate with restricted MISP content, potentially learning information about otherwise inaccessible events or attributes.","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":"MISP OnDemand Correlation Engine Missing Access Control Allows Disclosure of Restricted Correlations","id":"CVE-2026-85226","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"misp-project:misp","products":["misp-project:misp"],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Reflected Cross-Site Scripting in MISP Event Filtering via taggedAttributes and galaxyAttachedAttributes Parameters","id":"CVE-2026-85227"},"packages":[],"prev":{"headline":"code-projects Doctor Appointment System patient_login.php sql injection","id":"CVE-2026-85225"},"products":["misp"],"published":"2026-09-03","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":"2026-09-03","vendors":["misp"]},"summary":"Authenticated users can view restricted correlation data due to missing access control checks in the OnDemand correlation engine.","url":"https://insights.sbomify.com/CVE-2026-85226/"}
