It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-90895 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-2026-90895/ (Markdown: https://insights.sbomify.com/CVE-2026-90895/index.md)","id":"CVE-2026-90895","markdown":"https://insights.sbomify.com/CVE-2026-90895/index.md","name":"CVE-2026-90895","record":{"aliases":["GHSA-rx79-g748-j44m"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"MISP threat sharing platform","requires_auth":"low_privilege","summary":"Attackers can bypass CLI authorization checks to view restricted feeds, sharing groups, and exposed credentials in MISP.","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:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"},{"id":"CWE-522","name":"Insufficiently Protected Credentials"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"},{"id":"CWE-150","name":"Improper Neutralization of Escape, Meta, or Control Sequences"}],"description":"Affected versions of MISP’s interactive CLI shell implement access control independently from the normal web application, causing several authorization inconsistencies.\n\nThe patch shows that CLI access could differ from the web application in multiple security-sensitive areas:\n\n - feed listings did not enforce the same lookup_visible restrictions for non-host-organisation users;\n - feed detail access did not enforce the same host-organisation/site-admin authorization as FeedsController::view();\n - Feed.headers, which can contain HTTP authorization credentials, could be exposed instead of being hidden or masked;\n - server synchronization authkey values were not explicitly hidden from CLI detail output;\n - sharing-group detail access did not consistently use SharingGroup::checkIfAuthorised();\n - the use command could establish context for a record without first proving that the user was authorized to view that record\n\nThe commit additionally hardens pagination and terminal rendering, including neutralization of terminal control sequences found in database-backed values. Those are important hardening changes, but the main vulnerability is the CLI authorization/data-disclosure mismatch.\n\nVersion affected: ≤2.5.45","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 Interactive CLI Shell: Authorization Bypass, Credential Exposure, and Terminal Injection","id":"CVE-2026-90895","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":"Missing authentication in Ecommerce Template checkout session endpoint allows unauthenticated disclosure of buyer PII","id":"CVE-2026-90896"},"packages":[],"prev":{"headline":"Parallels Desktop local privilege escalation via appliance extract argument injection","id":"CVE-2026-90894"},"products":["MISP"],"published":"2026-09-14","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":"2026-09-14","vendors":["MISP"]},"summary":"Attackers can bypass CLI authorization checks to view restricted feeds, sharing groups, and exposed credentials in MISP.","url":"https://insights.sbomify.com/CVE-2026-90895/"}
