Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-39901 exists.\n\nAffected packages and fixed versions:\n- github.com/monetr/monetr (Go): affected all versions; fixed in 1.12.3\n- github.com/monetr/monetr (Go): affected all versions; fixed in 1.12.3\n- github.com/monetr/monetr (Go): affected all versions; fixed in 1.12.3\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-2026-39901/ (Markdown: https://insights.sbomify.com/CVE-2026-39901/index.md)","id":"CVE-2026-39901","markdown":"https://insights.sbomify.com/CVE-2026-39901/index.md","name":"CVE-2026-39901","record":{"aliases":["GHSA-hqxq-hwqf-wg83","GO-2026-5434"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"monetr budgeting application","requires_auth":"low_privilege","summary":"Authenticated users can bypass deletion protections to soft-delete synced transactions via the update endpoint, hiding records from views.","user_interaction":"required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":5.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-285","name":"Improper Authorization"}],"description":"monetr is a budgeting application focused on planning for recurring expenses. Prior to 1.12.3, a transaction integrity flaw allows an authenticated tenant user to soft-delete synced non-manual transactions through the transaction update endpoint, despite the application explicitly blocking deletion of those transactions via the normal DELETE path. This bypass undermines the intended protection for imported transaction records and allows protected transactions to be hidden from normal views.
