An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2025-27377 in the wild and no public exploit code.\n\nAffected product: Altium Designer. 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-2025-27377/ (Markdown: https://insights.sbomify.com/CVE-2025-27377/index.md)","id":"CVE-2025-27377","markdown":"https://insights.sbomify.com/CVE-2025-27377/index.md","name":"CVE-2025-27377","record":{"aliases":["GHSA-xfvg-p8x9-f25q"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["data_read","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"PCB design software","requires_auth":"none","summary":"Attackers can intercept traffic and steal credentials or design data due to missing certificate validation in Altium Designer cloud connections.","user_interaction":"required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Altium","cpe":[{"product":"designer","vendor":"altium"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"Altium Designer version 24.9.0 does not validate self-signed server certificates for cloud connections.
