Apigee hybrid Javacallout policy: Improper Control of Dynamically-Managed Code Resources
CVE-2025-13426 is a high-severity improper control of dynamically-managed code resources vulnerability in Apigee hybrid Javacallout policy from Google Cloud, with a CVSS 4.0 base score of 8.7 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists versions Hybrid_1.11.2, Hybrid_1.12.4, Hybrid_1.13.3 as the first without the flaw, so updating Apigee hybrid Javacallout policy to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.45% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Apigee hybrid Javacallout policy to Hybrid_1.11.2 or Hybrid_1.12.4 or Hybrid_1.13.3 or Hybrid_1.14.1, whichever matches your release line, or a later version.

Official description
A vulnerability exists in Google Apigee's JavaCallout policy https://docs.apigee.com/api-platform/reference/policies/java-callout-policy that allows for remote code execution. It is possible for a user to write a JavaCallout that injected a malicious object into the MessageContext to execute arbitrary Java code and system commands at runtime, leading to unauthorized access to data, lateral movement within the network, and access to backend systems. The Apigee hybrid versions below have all been updated to protect from this vulnerability: * Hybrid_1.11.2+ * Hybrid_1.12.4+ * Hybrid_1.13.3+ * Hybrid_1.14.1+ * OPDK_5202+ * OPDK_5300+

The underlying weakness: Improper Control of Dynamically-Managed Code Resources
The product does not properly restrict reading from or writing to dynamically-managed code resources such as variables, objects, classes, attributes, functions, or executable instructions or statements.
How developers prevent this class of flaw
- For any externally-influenced input, check the input against an allowlist of acceptable values.
- Refactor the code so that it does not need to be dynamically managed.
