Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-1181 in the wild and no public exploit code.\n\nAffected product: Altium 365. 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-2026-1181/ (Markdown: https://insights.sbomify.com/CVE-2026-1181/index.md)","id":"CVE-2026-1181","markdown":"https://insights.sbomify.com/CVE-2026-1181/index.md","name":"CVE-2026-1181","record":{"aliases":["GHSA-pfq7-53pj-q6wc"],"analysis":{"component_type":"cloud_service","fix_type":"configuration_change","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Altium 365 cloud service","requires_auth":"low_privilege","summary":"Overly permissive CORS settings allow cross-origin access to authenticated workspace APIs, enabling data theft and control bypass.","user_interaction":"required","vuln_class":"misconfiguration"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Altium","cpe":[],"cvss":{"score":9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-942","name":"Permissive Cross-domain Security Policy with Untrusted Domains"},{"id":"CWE-284","name":"Improper Access Control"}],"description":"Altium 365 workspace endpoints were configured with an overly permissive Cross-Origin Resource Sharing (CORS) policy that allowed credentialed cross-origin requests from other Altium-controlled subdomains, including forum.live.altium.com.
