🐛 Remove internal error details from HTTP error responses (#11288)
* 🚑 Remove internal error details from HTTP error responses

PostgreSQL exceptions, I/O exceptions, and unhandled errors were
leaking raw database messages (table names, constraint names,
SQLSTATE codes), filesystem paths, and internal exception details
to API clients via :hint, :state, and :path response fields.

Remove these fields from server-error responses while keeping
full error context in server-side logs for operators.

Closes #11287

* 🚑 Strip internal fields and map PG errors to safe messages

Complete the security fix for GHSA-r8wx-23q6-w3gf by addressing
the incomplete redaction found in code review.

Add strip-internal-fields helper to dissoc :hint, :state, :path,
and :context from error response data in three handlers that
previously passed raw ex-data through to clients:

- handle-error :internal
- handle-exception :default (else branch)
- handle-error :assertion (else branch)

Add pgsql-state->message to map PostgreSQL SQLSTATE codes to safe,
client-facing messages (e.g. 23505 → "A conflicting entry already
exists") instead of returning raw PG error text. Include :message
in all PSQLException response branches.

Add regression tests asserting :hint, :state, :path, :context are
absent from responses for :internal and unhandled ex-info errors.

Closes #11287

* 🚑 Keep :hint in error protocol, fix unsafe sources

Refine the security fix based on code review feedback.

Keep :hint as part of the error protocol — it is essential for
controlled error communication. Remove it from strip-internal-fields
(which now only strips :state, :path, :context).

Fix the actual sources of unsafe :hint values:

- http/middleware.clj: replace (ex-message cause) with safe static
  strings for IllegalArgumentException, RequestTooBigException, and
  EOFException. These :validation errors return ex-data verbatim
  to clients, so raw exception messages were leaking internals.

- PSQLException handler: use :hint instead of :message for the
  SQLSTATE-mapped messages, staying consistent with the error
  protocol.

Update tests to assert :hint is present (with safe static values)
in :internal and unhandled ex-info responses, and absent only from
bare RuntimeException and IOException responses.

Closes #11287

Penpot is the open-source design platform for teams that build digital products at scale.

Penpots key strength lies in giving you full ownership of your design infrastructure. Built on open source and designed for self-hosting, it puts teams in complete control of their design environment supporting strict compliance and governance requirements. Whether used in the browser or deployed on your own servers, Penpot works with open standards like SVG, CSS, HTML, and JSON.

Real-time collaboration strengthens this foundation, helping teams scale and bring design closer to the product through top-tier capabilities. Additionally, developers feel at home using Penpot, because design is expressed as code, enabling a direct translation and shipping products faster.

Best-in-class native Design Tokens provide a single source of truth between design and development. They ensure consistency, improve collaboration, and make it easier to manage complex design systems.

The MCP server takes it further by enabling multi-directional workflows between design and code. A powerful open API and plugin system makes the workspace programmable, enabling automation, AI-driven workflows, and integrations with the tools and systems you already use.

With CSS Grid and Flex Layout, teams can design responsive interfaces that behave like real code from the start.

Combined, these features turn Penpot into a full-stack design platform for building scalable design systems and fully integrated product development processes.

If your organization is scaling and needs extra support, were here to help. Talk to us

Why Penpot

Penpot connects design, code, and AI workflows through a code-based approach, making designs readable by developers and AI via the MCP server. This approach helps teams ship whats actually designed and manage design systems at scale with powerful design tokens. As a self-hosted, open-source and real-time collaboration platform, Penpot offers full flexibility, security, and ownership without vendor lock-in. Learn more about why Penpot is the platform for your team.

Plugin system

Penpot plugins let you expand the platform's capabilities, give you the flexibility to integrate it with other apps, and design custom solutions.

Designed for developers

Penpot was built to serve both designers and developers and create a fluid design-code process. You have the choice to enjoy real-time collaboration or play "solo".

Inspect mode

Work with ready-to-use code and make your workflow easy and fast. The inspect tab gives instant access to SVG, CSS and HTML code.

Integrations

Penpot offers integration into the development toolchain, thanks to its support for webhooks and an API accessible through access tokens.

Building Design Systems: design tokens, components and variants

Penpot brings design systems to code-minded teams: a single source of truth with native Design Tokens, Components, and Variants for scalable, reusable, and consistent UI across projects and platforms.
