GHSA-xw45-cc32-442f
LOWGHSA-xw45-cc32-442f is a low-severity (CVSS 2.7) Improper Input Validation vulnerability in github.com/ellanetworks/core. O3 Security confirms whether GHSA-xw45-cc32-442f is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Ella Core Has Audit Log Falsification via Path/Body IMSI Mismatch in UpdateSubscriber
Blast Radius
github.com/ellanetworks/coreReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
Summary
The PUT /api/v1/subscriber/{imsi} API accepts an IMSI identifier from both the URL path and the JSON request body but never verifies they match. This allows an authenticated NetworkManager to modify any subscriber's policy while the audit trail records a fabricated or unrelated subscriber IMSI.
Impact
A NetworkManager or Admin can modify any subscriber's QoS policy (potentially degrading service or altering traffic routing) while the audit log attributes the change to a non-existent or unrelated subscriber. Post-incident forensic searches for the affected subscriber's IMSI would find no matching audit entries.
Fix
Remove the IMSI as a body param and use the path param as a single source of truth.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/ellanetworks/core. 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 github.com/ellanetworks/core to 1.8.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-xw45-cc32-442f 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 GHSA-xw45-cc32-442f 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 GHSA-xw45-cc32-442f. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
