Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-9129 in the wild and no public exploit code.\n\nAffected product: Altium Enterprise Server. 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-2026-9129/ (Markdown: https://insights.sbomify.com/CVE-2026-9129/index.md)","id":"CVE-2026-9129","markdown":"https://insights.sbomify.com/CVE-2026-9129/index.md","name":"CVE-2026-9129","record":{"aliases":["GHSA-3qfq-f4q6-pq76"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","privilege_escalation"],"network_reachable":"yes","non_default_config":true,"product_category":"Altium Enterprise Server","requires_auth":"low_privilege","summary":"Authenticated users can read arbitrary files on on-premise servers, exposing secrets and enabling full compromise.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Altium","cpe":[],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","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":"A path traversal vulnerability exists in the Altium Enterprise Server Viewer StorageController due to improper handling of file path route parameters. On on-premise deployments that use local filesystem storage, a regular authenticated user can supply a URL-encoded absolute path (such as an encoded drive letter) in a Viewer storage API request, causing the configured storage root to be discarded and allowing arbitrary files to be read from the server filesystem.\n\nBecause the readable files include the server's master configuration, which stores database credentials, signing key locations, certificate passwords, and OAuth secrets, exploitation can lead to disclosure of all server secrets and full compromise of the server and its data. Cloud deployments are not affected, as they use object storage and do not enable this component.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Path Traversal in Altium Enterprise Server Viewer StorageController Allows Arbitrary File Read","id":"CVE-2026-9129","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Langflow OSS is affected by arbitrary code execution in custom component validation and trusted code enforcement","id":"CVE-2026-9130"},"packages":[],"prev":{"headline":"Studio 5000 Logix Designer® – Multiple Vulnerabilities","id":"CVE-2026-9128"},"products":["Altium Enterprise Server"],"published":"2026-05-20","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":"2026-05-20","vendors":["Altium"]},"summary":"Authenticated users can read arbitrary files on on-premise servers, exposing secrets and enabling full compromise.","url":"https://insights.sbomify.com/CVE-2026-9129/"}
