Real-World Exposure
SamlyReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Hex packages — download data is not available via public APIs for these ecosystems.
Description
In the Samly package before 1.4.0 for Elixir, Samly.State.Store.get_assertion/3 can return an expired session, which interferes with access control because Samly.AuthHandler uses a cached session and does not replace it, even after expiry.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for Samly, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update Samly to 1.4.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-25718 is resolved across your whole dependency graph.
Workarounds
Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
