Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-54360 in the wild and no public exploit code.\n\nAffected product: 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-2026-54360/ (Markdown: https://insights.sbomify.com/CVE-2026-54360/index.md)","id":"CVE-2026-54360","markdown":"https://insights.sbomify.com/CVE-2026-54360/index.md","name":"CVE-2026-54360","record":{"aliases":["GHSA-j794-65mg-q3vf"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_modify","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"MISP threat sharing","requires_auth":"low_privilege","summary":"Authenticated users can hijack existing sharing groups via mass assignment, bypassing access controls to modify or view unauthorized shared data.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CIRCL","cpe":[],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:L/VA:N/SC:H/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"A mass assignment vulnerability exists in MISP’s sharing group creation endpoint. When creating a new sharing group, the controller did not remove a user-supplied id field before saving the submitted data. In CakePHP, supplying a primary key in the save data can cause a create() followed by save() operation to update an existing record instead of creating a new one.\n\nAn authenticated user with permission to add sharing groups could therefore submit the identifier of an existing sharing group and modify that sharing group without passing the normal edit access-control checks. This may allow the attacker to take over or alter sharing groups they do not otherwise have access to, potentially affecting the confidentiality and integrity of information shared through those groups.\n\nAffected component:\napp/Controller/SharingGroupsController.php, add() action","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 sharing group creation mass assignment allows unauthorized takeover of existing sharing groups","id":"CVE-2026-54360","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"MISP mass assignment vulnerabilities allow unauthorized modification of ownership and delegation records","id":"CVE-2026-54361"},"packages":[],"prev":{"headline":"MISP automation endpoints may be exposed to CSRF when Sec-Fetch-Site protection is disabled by default","id":"CVE-2026-54359"},"products":["misp"],"published":"2026-06-12","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":"partial"},"state":"PUBLISHED","updated":"2026-06-15","vendors":["misp"]},"summary":"Authenticated users can hijack existing sharing groups via mass assignment, bypassing access controls to modify or view unauthorized shared data.","url":"https://insights.sbomify.com/CVE-2026-54360/"}
