Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-73140 in the wild and no public exploit code.\n\nAffected product: MISP cti-transmute. 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-2026-73140/ (Markdown: https://insights.sbomify.com/CVE-2026-73140/index.md)","id":"CVE-2026-73140","markdown":"https://insights.sbomify.com/CVE-2026-73140/index.md","name":"CVE-2026-73140","record":{"aliases":["GHSA-vrrh-vgmq-m54x"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"MISP cti-transmute","requires_auth":"low_privilege","summary":"Attackers can export evaluation reports to view private comments and author names, bypassing access controls in MISP cti-transmute.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CIRCL","cpe":[],"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:L/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"Affected versions of cti-transmute fail to apply comment-level access-control rules when generating evaluation report exports. Although normal comment retrieval filters comments according to conversion visibility, comment privacy, ownership, authorship, and administrative privileges, build_evaluation_report() previously included all evaluation comments without applying those rules.\n\nConsequently, a user who was authorized to view a conversion could export its evaluation report as Markdown or PDF and obtain private evaluation comments that should only have been visible to the conversion owner, the comment author, or an administrator.
