An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-77438 exists.\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-2026-77438/ (Markdown: https://insights.sbomify.com/CVE-2026-77438/index.md)","id":"CVE-2026-77438","markdown":"https://insights.sbomify.com/CVE-2026-77438/index.md","name":"CVE-2026-77438","record":{"aliases":["GHSA-6rxv-6w3q-7mv9"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Trilium note-taking app","requires_auth":"none","summary":"Unauthenticated attackers can bypass password and visibility controls on shared notes via the search endpoint, disclosing protected content.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"trilium","vendor":"triliumnotes"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Trilium is an open-source hierarchical note-taking application. In versions up to and including 0.103.0, the public share-search endpoint does not enforce the per-note shareCredentials and shareHiddenFromTree controls, allowing an unauthenticated visitor to read the titles, tree paths, and content of protected shared notes. The endpoint authorizes only the ancestor note supplied in the request and then runs a full-text search across the entire published subtree, returning each matching note's title, share identifier, and hierarchical path without re-checking whether that individual note requires a share password or is hidden from the navigation tree. Because the search matches note content, an attacker can enumerate protected notes and use the endpoint as a boolean oracle that confirms arbitrary substrings, recovering the full contents of notes that should be gated behind a password. This issue is fixed in version 0.104.0.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"Trilium unauthenticated share-search discloses password-protected and hidden shared notes","id":"CVE-2026-77438","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"exists/2 predicate silently dropped on limited relationships with a parent() filter in AshSql","id":"CVE-2026-77454"},"packages":[],"prev":{"headline":"FileRise: Insecure default cryptographic key fallback in manual installs","id":"CVE-2026-77427"},"products":["Trilium"],"published":"2026-08-27","related":[{"cvss_score":9.3,"headline":"Trilium: Malicious import with GeoMap marker title XSS leads to RCE on the desktop client","id":"CVE-2026-48996","kev_date_added":null,"published":"2026-08-27"},{"cvss_score":9.3,"headline":"Trilium: Note Import to RCE via Mind Elixir dangerouslySetInnerHtml","id":"CVE-2026-53578","kev_date_added":null,"published":"2026-08-27"},{"cvss_score":9.3,"headline":"Trilium: Note Import to RCE via Book Note","id":"CVE-2026-53579","kev_date_added":null,"published":"2026-08-27"},{"cvss_score":8.6,"headline":"Code injection in Trilium","id":"CVE-2026-47727","kev_date_added":null,"published":"2026-08-27"},{"cvss_score":8.1,"headline":"Trilium arbitrary file read and denial of service via file:// URLs in the automatic image-download feature","id":"CVE-2026-53580","kev_date_added":null,"published":"2026-08-27"},{"cvss_score":7.4,"headline":"Trilium Notes has a Timing Attack Vulnerability in /api/login/sync","id":"CVE-2025-68621","kev_date_added":null,"published":"2026-02-06"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-08-28","vendors":["TriliumNext"]},"summary":"Unauthenticated attackers can bypass password and visibility controls on shared notes via the search endpoint, disclosing protected content.","url":"https://insights.sbomify.com/CVE-2026-77438/"}
