It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-82737 exists.\n\nAffected packages and fixed versions:\n- ash (Hex): affected from 2.14.13; fixed in 3.32.2\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-2026-82737/ (Markdown: https://insights.sbomify.com/CVE-2026-82737/index.md)","id":"CVE-2026-82737","markdown":"https://insights.sbomify.com/CVE-2026-82737/index.md","name":"CVE-2026-82737","record":{"aliases":["EEF-CVE-2026-82737","GHSA-68q3-w4w3-2gfv"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","data_modify"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Elixir Ash framework","requires_auth":"none","summary":"An attacker can cause denial of service and data corruption by submitting vectors with more than 65,535 elements, triggering an integer overflow in the Ash library.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"EEF","cpe":[],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"Integer Overflow or Wraparound vulnerability in ash-project ash lets an attacker corrupt a stored vector and crash later reads of it by submitting a vector with more than 65,535 elements.\n\nAsh.Vector.new/1 (lib/ash/vector.ex) encodes a vector as \u003c\u003cdim::unsigned-16, 0::unsigned-16\u003e\u003e followed by the element floats, packing the element count into a 16-bit field without checking its range.
