Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-55381 exists.\n\nAffected product: InvoiceShelf. 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-2026-55381/ (Markdown: https://insights.sbomify.com/CVE-2026-55381/index.md)","id":"CVE-2026-55381","markdown":"https://insights.sbomify.com/CVE-2026-55381/index.md","name":"CVE-2026-55381","record":{"aliases":["GHSA-j2vg-rxqr-5vc9"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"InvoiceShelf web app","requires_auth":"low_privilege","summary":"Authenticated users can read and modify other companies' estimates due to missing authorization checks during invoice conversion.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"InvoiceShelf is an open-source web \u0026 mobile app that helps track expenses, payments and create professional invoices and estimates. Prior to version 2.4.0, POST /api/v1/estimates/{estimate}/convert-to-invoice in ConvertEstimateController authorizes only the caller's create-invoice ability and does not authorize access to the route-bound Estimate. Because route-model binding can resolve an estimate from any company, an authenticated user with create-invoice ability can copy another company's line items, prices, totals, taxes, notes, currency, and customer data into an invoice in the attacker's company. The victim company's configured conversion action reaches checkForEstimateConvertAction and can also change or delete the original estimate.
