GHSA-rhrq-64mq-hf9h is a medium-severity (CVSS 5.5) CWE-369 vulnerability in tensorflow. O3 Security confirms whether GHSA-rhrq-64mq-hf9h is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description
Impact
The implementation of division in TFLite is vulnerable to a division by 0 error
There is no check that the divisor tensor does not contain zero elements.
Patches
We have patched the issue in GitHub commit 1e206baedf8bef0334cca3eb92bab134ef525a28.
The fix will be included in TensorFlow 2.6.0. We will also cherrypick this commit on TensorFlow 2.5.1, TensorFlow 2.4.3, and TensorFlow 2.3.4, as these are also affected and still in supported range.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for tensorflow. 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 tensorflow to 2.3.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rhrq-64mq-hf9h 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-rhrq-64mq-hf9h 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-rhrq-64mq-hf9h. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-rhrq-64mq-hf9h in your dependencies?
O3 detects GHSA-rhrq-64mq-hf9h across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
