An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-50179 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- @actual-app/web (npm): affected all versions; fixed in 26.6.0\n- @actual-app/web (npm): affected all versions; fixed in 26.6.0\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-2026-50179/ (Markdown: https://insights.sbomify.com/CVE-2026-50179/index.md)","id":"CVE-2026-50179","markdown":"https://insights.sbomify.com/CVE-2026-50179/index.md","name":"CVE-2026-50179","record":{"aliases":["GHSA-xqjm-27pc-rvwm"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["data_read","other"],"network_reachable":"yes","non_default_config":false,"product_category":"Personal finance tool","requires_auth":"none","summary":"Attackers can inject malicious formulas into CSV exports via imported fields, leading to data exfiltration when opened in spreadsheet software.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":4.2,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-1236","name":"Improper Neutralization of Formula Elements in a CSV File"}],"description":"Actual is a local-first personal finance tool.
