An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-82586 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- ash_lua (Hex): affected from 0.1.0; fixed in 0.2.1\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-2026-82586/ (Markdown: https://insights.sbomify.com/CVE-2026-82586/index.md)","id":"CVE-2026-82586","markdown":"https://insights.sbomify.com/CVE-2026-82586/index.md","name":"CVE-2026-82586","record":{"aliases":["EEF-CVE-2026-82586","GHSA-37jv-wc37-fhcw"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"AshLua library","requires_auth":"none","summary":"A user-supplied Lua script can bypass exposed-field restrictions to read private attributes, including sensitive data like hashed passwords.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"EEF","cpe":[],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-424","name":"Improper Protection of Alternate Path"}],"description":"Improper Protection of Alternate Path vulnerability in ash-project ash_lua allows a user-supplied Lua script to read attributes that are not on the exposed-field allow-list.\n\nAshLua exposes Ash resources to Lua scripts, gated by a manifest declaring which fields are exposed.
