An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-68621 in the wild and no public exploit code.\n\nAffected product: TriliumNext Trilium. 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-2025-68621/ (Markdown: https://insights.sbomify.com/CVE-2025-68621/index.md)","id":"CVE-2025-68621","markdown":"https://insights.sbomify.com/CVE-2025-68621/index.md","name":"CVE-2025-68621","record":{"aliases":["GHSA-hxf6-58cx-qq3x"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["account_takeover","data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Trilium Notes","requires_auth":"none","summary":"Attackers can bypass authentication via timing attacks on the sync endpoint, gaining full read/write access to the victim's knowledge base.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"trilium","vendor":"triliumnotes"}],"cvss":{"score":7.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-208","name":"Observable Timing Discrepancy"}],"description":"Trilium Notes is an open-source, cross-platform hierarchical note taking application with focus on building large personal knowledge bases.
