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.
AshLua exposes Ash resources to Lua scripts, gated by a manifest declaring which fields are exposed. The read action's operation aggregate path in AshLua.Runtime took the field name straight from the Lua call and resolved it with only String.to_existing_atom and Ash.Query.Aggregate.new!, neither of which consults the exposed-field allow-list the normal fields path enforces. A script can therefore read the value of any attribute of any record the actor may read, including private sensitive?: true columns, via resource.read({ operation = {"list", "hashed_password"} }); min and max give a value oracle. Anyone able to submit or influence a Lua script can reach this.
This issue affects ash_lua: from 0.1.0 before 0.2.1.
Detection & mitigation playbook
VulnerabilityDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for the affected component. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Remediation status
No patched version of the affected component has shipped for CVE-2026-82586 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether CVE-2026-82586 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-82586. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
