Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-95693 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-2026-95693/ (Markdown: https://insights.sbomify.com/CVE-2026-95693/index.md)","id":"CVE-2026-95693","markdown":"https://insights.sbomify.com/CVE-2026-95693/index.md","name":"CVE-2026-95693","record":{"aliases":["GHSA-f496-75v4-rv5q"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"MISP threat sharing","requires_auth":"low_privilege","summary":"Authenticated users can enumerate server files and types via forged upload paths, leaking filesystem layout without reading contents.","user_interaction":"not_required","vuln_class":"information_disclosure"},"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:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"In MISP, the EventReport::uploadPicture method in processed a caller-supplied tmp_name field by invoking file_exists(), mime_content_type(), and exif_imagetype() on the supplied path before verifying that the value was a genuine PHP upload via is_uploaded_file(). An authenticated user holding the perm_add permission could supply an arbitrary filesystem path as the tmp_name value. The application would then probe that path and return distinct validation error messages depending on whether the file existed, its MIME type, or its image format. By observing the differing error responses, an attacker could enumerate the existence of files at arbitrary paths on the MISP server and determine their type. \n\nThis constitutes an information disclosure vulnerability: the server's filesystem layout and file types are leaked to any user with the perm_add role without requiring administrative access. \n\nThe vulnerability does not allow reading file contents, writing files, or executing code, but it can aid further attacks by revealing sensitive file locations (e.g., configuration files, private keys, or other artifacts) present on the host.","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 Information Disclosure via Forged Upload Path","id":"CVE-2026-95693","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":"IBM WebSphere Application Server Liberty Incorrect Authorization","id":"CVE-2026-95695"},"packages":[],"prev":{"headline":"Privilege escalation in WPC Shop as a Customer for WooCommerce","id":"CVE-2026-95687"},"products":["MISP"],"published":"2026-09-22","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":"2026-09-22","vendors":["MISP"]},"summary":"Authenticated users can enumerate server files and types via forged upload paths, leaking filesystem layout without reading contents.","url":"https://insights.sbomify.com/CVE-2026-95693/"}
