GHSA-xqfj-cr6q-pc8w

LOWFix: tensorflow/tensorflow@1dc6a7c

GHSA-xqfj-cr6q-pc8w is a low-severity (CVSS 2.5) CWE-755 vulnerability in tensorflow. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether GHSA-xqfj-cr6q-pc8w is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Crash in `tf.transpose` with complex inputs

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.

Description

Impact

Passing a complex argument to tf.transpose at the same time as passing conjugate=True argument results in a crash:

import tensorflow as tf
tf.transpose(conjugate=True, a=complex(1))

Patches

We have received a patch for the issue in GitHub commit 1dc6a7ce6e0b3e27a7ae650bfc05b195ca793f88.

The fix will be included in TensorFlow 2.5.0. We will also cherrypick this commit on TensorFlow 2.4.2, TensorFlow 2.3.3, TensorFlow 2.2.3 and TensorFlow 2.1.4, as these are also affected and still in supported range.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    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.

  2. Fix

    Update tensorflow to 2.1.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-xqfj-cr6q-pc8w is resolved across your whole dependency graph.

  3. 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.

  4. How O3 protects you

    O3 pinpoints whether GHSA-xqfj-cr6q-pc8w 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-xqfj-cr6q-pc8w. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
