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-2026-69659 exists.\n\nAffected packages and fixed versions:\n- ash (Hex): affected from 1.17.0; fixed in 3.31.1\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-2026-69659/ (Markdown: https://insights.sbomify.com/CVE-2026-69659/index.md)","id":"CVE-2026-69659","markdown":"https://insights.sbomify.com/CVE-2026-69659/index.md","name":"CVE-2026-69659","record":{"aliases":["EEF-CVE-2026-69659","GHSA-j35q-v8h8-7mwq"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Elixir Ash library","requires_auth":"none","summary":"Attackers can cause denial of service by sending crafted keyset pagination cursors that trigger memory exhaustion via unsafe deserialization.","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":5.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Uncontrolled Resource Consumption vulnerability in ash-project ash allows an attacker to exhaust the memory of the node via a crafted keyset pagination cursor.\n\nRead actions with keyset pagination deserialize the client-supplied page[:after] or page[:before] cursor in decode_values/2 in lib/ash/page/keyset.ex, which base64-decodes the value and passes it to :erlang.binary_to_term/2 without bounding its size. The Erlang external term format supports zlib-compressed payloads, which the decoder inflates transparently, so a cursor of a few kilobytes can allocate tens of megabytes of heap in a single call. Ash itself only ever encodes cursors uncompressed, so the decoder accepts a term shape its encoder never produces. Concurrent requests aggregate these allocations and can terminate the node.\n\nThis issue affects ash: from 1.17.0 before 3.31.1.","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":"Memory exhaustion via unbounded deserialization of keyset pagination cursors in Ash.Page.Keyset","id":"CVE-2026-69659","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Hex","product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":1,"n_references":4,"next":{"headline":"Toptech TMS7 and TopHAT Eval Injection","id":"CVE-2026-69662"},"packages":[{"ecosystem":"Hex","fixed":["3.31.1"],"introduced":["1.17.0"],"last_affected":[],"package":"ash","purl":"pkg:hex/ash","source":"EEF-CVE-2026-69659"}],"prev":{"headline":"Ebyte NA111-M Cleartext Transmission of Sensitive Information","id":"CVE-2026-69658"},"products":["ash"],"published":"2026-08-09","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":7.5,"headline":"Filter expression injection via forged keyset pagination cursor in Ash","id":"CVE-2026-67579","kev_date_added":null,"published":"2026-08-12"}],"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":"partial"},"state":"PUBLISHED","updated":"2026-08-10","vendors":["ash-project"]},"summary":"Attackers can cause denial of service by sending crafted keyset pagination cursors that trigger memory exhaustion via unsafe deserialization.","url":"https://insights.sbomify.com/CVE-2026-69659/"}
