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-2026-77454 exists.\n\nAffected packages and fixed versions:\n- ash_sql (Hex): affected from 0.4.1; fixed in 0.7.1\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-2026-77454/ (Markdown: https://insights.sbomify.com/CVE-2026-77454/index.md)","id":"CVE-2026-77454","markdown":"https://insights.sbomify.com/CVE-2026-77454/index.md","name":"CVE-2026-77454","record":{"aliases":["EEF-CVE-2026-77454","GHSA-8v9m-8pxv-738c"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Elixir SQL library","requires_auth":"none","summary":"Attackers can bypass authorization policies in AshSql by exploiting a bug that silently drops exists predicates on limited relationships with parent filters.","user_interaction":"not_required","vuln_class":"missing_authorization"},"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:H/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"Incorrect Authorization vulnerability in ash-project ash_sql allows a caller to bypass a scoping or authorization filter expressed as exists/2 over a relationship that declares both a limit (or from_many?) and a parent(...)-referencing filter or sort.\n\nAshSql.Join.related_query/3 skips the caller-supplied exists predicate for such relationships and delegates it to limit_from_many/5. When the relationship's own filter or sort references parent(...), limit_from_many/5 takes a branch that drops both the limit and the predicate, emitting a bare correlated EXISTS with no predicate. The check then matches any record that has any related row. Most severely, when the expression backs a policy (for example authorize_if expr(exists(memberships, user_id == ^actor(:id)))), the actor-scoping condition disappears and the policy passes for any actor with any related row.\n\nThis issue affects ash_sql: from 0.4.1 before 0.7.1.","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":"exists/2 predicate silently dropped on limited relationships with a parent() filter in AshSql","id":"CVE-2026-77454","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Hex","product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":1,"n_references":4,"next":{"headline":"Argo CD: AppProject destination-namespace and resource restrictions bypassed by PreDelete/PostDelete resource hooks","id":"CVE-2026-77459"},"packages":[{"ecosystem":"Hex","fixed":["0.7.1"],"introduced":["0.4.1"],"last_affected":[],"package":"ash_sql","purl":"pkg:hex/ash_sql","source":"EEF-CVE-2026-77454"}],"prev":{"headline":"Trilium unauthenticated share-search discloses password-protected and hidden shared notes","id":"CVE-2026-77438"},"products":["ash_sql"],"published":"2026-08-30","related":[],"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":"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":"2026-08-31","vendors":["ash-project"]},"summary":"Attackers can bypass authorization policies in AshSql by exploiting a bug that silently drops exists predicates on limited relationships with parent filters.","url":"https://insights.sbomify.com/CVE-2026-77454/"}
