# What should teams do about Vulnerability Disclosure under UK PSTI Product Security?

UK PSTI Product Security guidance for Vulnerability Disclosure, with practical decisions, evidence, edge cases, and external source citations.

*Artifact Guide* *UK* *Vulnerability Disclosure*

## UK PSTI Product Security Vulnerability Disclosure

Vulnerability Disclosure decisions under UK PSTI Product Security should be written in operational language: who is in scope, what must happen, what evidence proves it, and when escalation is needed.

Use this guide to turn official requirements into scope, evidence, owner, and review decisions. This guidance is practical, source-linked, and should be validated against current legal and policy requirements before implementation.

This page helps you determine which UK PSTI Product Security duties apply, who owns each action, required evidence, and the review path for escalation decisions. The disclosure rule requires manufacturers to publish information on how to report security issues.

## How should teams handle vulnerability disclosure under UK PSTI Product Security?

Teams should treat vulnerability disclosure under the UK PSTI Act as a source-linked operating decision: confirm whether the product is a relevant connectable product and which manufacturer, importer, distributor, statement-of-compliance, vulnerability-disclosure, password, support-period, or OPSS enforcement duty is relevant, assign the team that can change the process, and keep evidence showing the action and review trigger.

The safest first step is to classify the product and supply-chain role before deciding whether the duty belongs to the manufacturer, importer, distributor, or all of them.

- Write the vulnerability-disclosure decision in one sentence before drafting controls.
- Attach the external source URL and a short source quote to the evidence record.
- Route unclear cases to legal, privacy, security, or compliance review before launch.

## What evidence should teams keep for vulnerability disclosure under UK PSTI Product Security?

Useful evidence is not just a product-security policy. Keep the source, product facts, password and vulnerability-disclosure proof, support-period statement, supply-chain role mapping, and statement-of-compliance approval together.

- Source URL and quote used for the decision.
- Scope notes, screenshots, data-flow or system references, and role mapping.
- Implementation ticket, approval record, exception notes, and review date.

## Which mistakes create risk when handling vulnerability disclosure under UK PSTI Product Security?

The common failure pattern is using a generic IoT security claim without proving the PSTI product scope, exact responsible role, customer-facing support information, and statement-of-compliance record.

- Using an old threshold, deadline, source page, or contract template without checking current source text.
- Treating a source-linked exception as a general exemption for every product or data flow.
- Publishing notices, controls, or answers that do not match the actual product behavior.
