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-2026-50554 exists.\n\nAffected packages and fixed versions:\n- github.com/enchant97/note-mark/backend (Go): affected all versions; fixed in 0.0.0-20260601210758-9c9b72740f22\n- github.com/enchant97/note-mark/backend (Go): affected all versions; fixed in 0.0.0-20260601210758-9c9b72740f22\n- github.com/enchant97/note-mark/backend (Go): affected all versions; fixed in 0.0.0-20260601210758-9c9b72740f22\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-2026-50554/ (Markdown: https://insights.sbomify.com/CVE-2026-50554/index.md)","id":"CVE-2026-50554","markdown":"https://insights.sbomify.com/CVE-2026-50554/index.md","name":"CVE-2026-50554","record":{"aliases":["GHSA-588f-fvcv-xhvf","GO-2026-5948"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Note Mark application","requires_auth":"none","summary":"Unauthenticated attackers can view metadata of soft-deleted notes in public books by exploiting an API parameter that bypasses soft-delete scoping.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-285","name":"Improper Authorization"},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Note Mark is an open-source note-taking application. Prior to version 0.19.5, GET /api/books/{bookID}/notes is an unauthenticated endpoint that accepts a \"deleted\" query parameter. When the request is ?deleted=true, the service runs the query with Unscoped() (bypassing GORM's soft-delete scope) but keeps the read-authorization clause as \"owner_id = ? OR is_public = ?\". As a result, any unauthenticated caller can enumerate the metadata of soft-deleted (\"trashed\") notes belonging to any public book — notes the owner explicitly deleted and expected to be removed from public view.
