CVE-2025-8325: Improper Access Control via Gateway API in Multiple WSO2 Products Allows Unauthorized Operations

Noroxi assessment

Priority: Monitor (action score 35/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.17% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.
  • Severity is disputed: the assigning authority (CNA) scores it 6.3, NVD 8.8.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

The software fails to enforce role-based access controls for certain Gateway API invocations. Users with the 'Internal/Everyone' role can invoke these APIs, bypassing intended permission checks. This same vulnerability also affects Internal Service APIs, potentially exposing them in WSO2 APIM 3.x versions. A malicious actor with a valid user account on a vulnerable deployment can perform sensitive operations against the Gateway REST API regardless of their actual roles or privileges. This could lead to unintended behavior or misuse, particularly in production environments.
