CVE-2025-48044
Ash has authorization bypass when bypass policy condition evaluates to true
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description
Incorrect Authorization vulnerability in ash-project ash allows Authentication Bypass. This vulnerability is associated with program files lib/ash/policy/policy.ex and program routines 'Elixir.Ash.Policy.Policy':expression/2.
This issue affects ash: from pkg:hex/[email protected] before pkg:hex/[email protected], from 3.6.3 before 3.7.1, from 79749c2685ea031ebb2de8cf60cc5edced6a8dd0 before 8b83efa225f657bfc3656ad8ee8485f9b2de923d.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ash. 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.
Fix
Update ash to 3.7.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-48044 is resolved across your whole dependency graph.
Workarounds
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-2025-48044 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-2025-48044. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2025-48044 in your dependencies?
O3 detects CVE-2025-48044 across Hex dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
