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-2026-67579 exists.\n\nAffected packages and fixed versions:\n- ash (Hex): affected from 1.17.0; fixed in 3.31.3\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-2026-67579/ (Markdown: https://insights.sbomify.com/CVE-2026-67579/index.md)","id":"CVE-2026-67579","markdown":"https://insights.sbomify.com/CVE-2026-67579/index.md","name":"CVE-2026-67579","record":{"aliases":["EEF-CVE-2026-67579","GHSA-3gq3-9xm3-c8v3"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Elixir Ash framework","requires_auth":"none","summary":"Unauthenticated attackers can inject malicious filter expressions via forged pagination cursors, leading to SQL injection or code execution in Ash applications.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"EEF","cpe":[{"product":"ash_framework","vendor":"ash-hq"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-89","name":"Improper Neutralization of Special Elements used in an SQL Command"},{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Deserialization of Untrusted Data vulnerability in ash-project ash allows an unauthenticated attacker to inject a filter expression through a forged keyset pagination cursor, resulting in SQL injection or code execution depending on the data layer.\n\nRead actions with keyset pagination decode the client-supplied page[:after] or page[:before] cursor in decode_values/2 in lib/ash/page/keyset.ex using non_executable_binary_to_term/2 with [:safe]. That guard blocks new atoms, funs, and ports, but not a struct built from atoms already interned in a running Ash application, so a decoded %Ash.Query.Call{} expression survives and is spliced into the keyset filter as a comparison value in do_filters/4 and evaluated. Because the cursor bypasses the Ash.Expr macro, the runtime never applies the private?/public? gate that would otherwise reject it. On AshPostgres the injected fragment is inlined into the SQL query; on the ETS and Simple data layers it is evaluated in-process as an arbitrary function call.\n\nThis issue affects ash: from 1.17.0 before 3.31.3.","ecosystems":["Hex"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Filter expression injection via forged keyset pagination cursor in Ash","id":"CVE-2026-67579","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Hex","product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":1,"n_references":4,"next":{"headline":"On-chain transfer proof is not single-use in mpp EVM payment method, enabling cross-challenge replay","id":"CVE-2026-67581"},"packages":[{"ecosystem":"Hex","fixed":["3.31.3"],"introduced":["1.17.0"],"last_affected":[],"package":"ash","purl":"pkg:hex/ash","source":"EEF-CVE-2026-67579"}],"prev":{"headline":"Missing authorization in FA-50","id":"CVE-2026-67578"},"products":["ash"],"published":"2026-08-12","related":[{"cvss_score":8.2,"headline":"Ash Framework: Ash.Type.Module.cast_input/2 atom exhaustion via unchecked Module.concat allows BEAM VM crash","id":"CVE-2026-34593","kev_date_added":null,"published":"2026-04-02"},{"cvss_score":5.9,"headline":"Memory exhaustion via unbounded deserialization of keyset pagination cursors in Ash.Page.Keyset","id":"CVE-2026-69659","kev_date_added":null,"published":"2026-08-09"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"Erlang Ecosystem Foundation","prefix":"EEF"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-13","vendors":["ash-project"]},"summary":"Unauthenticated attackers can inject malicious filter expressions via forged pagination cursors, leading to SQL injection or code execution in Ash applications.","url":"https://insights.sbomify.com/CVE-2026-67579/"}
