CVE-2026-90448
Application Programming Interface Improper Access Control
Description

A deployment mode intended to expose only read access to stored data proxies a set of application programming interface routes without restricting which request methods are allowed. One such route accepts a request that creates or overwrites a stored record, including an attacker-chosen identifier, using the application's own elevated backend credentials. This allows an authenticated user on a deployment intended to be read-only to forge or overwrite stored records that should not be modifiable in that deployment mode.

CVSS Scores
The Common Vulnerability Scoring System is a standardized framework for assessing the severity of vulnerabilities in software and systems. We collect and displays CVSS scores from various sources for each CVE.
Score Version Severity Vector Exploitability Score Impact Score Source
CVSS 4.0 HIGH 7d14cffa-0d7d-4270-9dc0-52cabd5a23a6
CVSS 4.0 HIGH [email protected]
Solution
Restrict HTTP methods and enforce granular access controls for API routes.
  • Limit API routes to necessary HTTP methods.
  • Implement strict authorization checks for all operations.
  • Review and restrict backend credential usage.
  • Ensure deployment modes enforce read-only access.
