CVE intelligence and bounded remediation
CVE-2025-12107 — Wso2 Identity Server security vulnerability
Due to the use of a vulnerable third-party Velocity template engine, a malicious actor with admin privilege may inject and execute arbitrary template syntax within server-side templates. Successful exploitation of this vulnerability could allow a malicious actor with admin privilege to inject and execute arbitrary template code on the server, potentially leading to remote code execution, data manipulation, or unauthorized access to sensitive information.

Matched remediation archetype
Command, code, expression, and template injection
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Trace untrusted values to process execution, interpreters, evaluators, template engines, dynamic imports, and administrative scripting features.
- Determine whether the affected path is reachable across each trust boundary and which service account or host privilege it inherits.
- Review configuration for optional execution features, unsafe compatibility modes, and shell invocation.
Remediate safely
- Replace string-built commands or evaluated code with fixed operations and structured argument APIs that do not invoke a shell.
- Use strict allowlists for operation identifiers and reject unexpected input before it reaches any interpreter.
- Update the affected component and add inert regression tests covering metacharacters, encoding variants, and alternate request paths.
