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-2026-90955 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-2026-90955/ (Markdown: https://insights.sbomify.com/CVE-2026-90955/index.md)","id":"CVE-2026-90955","markdown":"https://insights.sbomify.com/CVE-2026-90955/index.md","name":"CVE-2026-90955","record":{"aliases":["GHSA-wxf7-wrjx-26cc"],"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","requires_auth":"high_privilege","summary":"MISP CLI shell fails to correctly log user identity and CLI markers, potentially obscuring audit trails and allowing actions to appear as standard web activity.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CIRCL","cpe":[],"cvss":{"score":4.6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:H/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-778","name":"Insufficient Logging"},{"id":"CWE-223","name":"Omission of Security-relevant Information"}],"description":"Affected versions of MISP’s interactive CLI shell do not reliably preserve the identity of the impersonated MISP user across audit logging.\n\nThe shell is designed to run actions as a supplied MISP user ID. However, the legacy SysLogLogable behavior stored that identity in behavior-instance state that could be overwritten when another model lazily attached the shared behavior. Consequently, subsequent CLI writes could lose the intended user attribution and be logged incorrectly. The commit also notes that CLI-originated records lacked a CLI marker, making them appear similar to ordinary web actions by that user.\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 CLI Shell Audit Logs Lose User Identity and CLI Marker After First Lazy Model Load","id":"CVE-2026-90955","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"MISP: Stored XSS via Inline-Served SVG Organisation Logos and Report Pictures","id":"CVE-2026-90957"},"packages":[],"prev":{"headline":"Busybox: busybox: dpkg-deb extraction-root escape via per-ar-member deferred symlink flush","id":"CVE-2026-90954"},"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":"partial"},"state":"PUBLISHED","updated":"2026-09-14","vendors":["MISP"]},"summary":"MISP CLI shell fails to correctly log user identity and CLI markers, potentially obscuring audit trails and allowing actions to appear as standard web activity.","url":"https://insights.sbomify.com/CVE-2026-90955/"}
