Open Redirect

Open Redirect: VulnerabilityVulnerabilityA technical or organizational weakness that can be exploited by a threat. enabling controlled redirection to arbitrary external destinations. The term is relevant to the assessment and design of modern security architectures and should be applied within the specific technical and organizational context.

How it works and where it fits

Technically, Open Redirect describes an attack path or a concrete method rather than a single suspicious event. A sound assessment separates prerequisites, entry point, objective, intermediate steps, and expected effect. The same technique can produce very different outcomes depending on system architecture, available privileges, exposure, and existing safeguards.

Practical security relevance

In practice, both preventive measures and observable traces matter. Secure configuration, restricted privileges, robust input and identity checks, and telemetry at affected trust boundaries all contribute. A single indicator rarely proves an attack; reliable detection, containment, and remediation require the combined context of timing, source, target, and observed impact.
