Detailsinfo

A vulnerability, which was classified as critical, was found in Penpot up to 2.13.1. This affects some unknown functionality of the component RPC Endpoint. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality. The summary by CVE is:

Penpot is an open-source design tool for design and code collaboration. Prior to version 2.13.2, an authenticated user can read arbitrary files from the server by supplying a local file path (e.g. `/etc/passwd`) as a font data chunk in the `create-font-variant` RPC endpoint, resulting in the file contents being stored and retrievable as a "font" asset. This is an arbitrary file read vulnerability. Any authenticated user with team edit permissions can read arbitrary files accessible to the Penpot backend process on the host filesystem. This can lead to exposure of sensitive system files, application secrets, database credentials, and private keys, potentially enabling further compromise of the server. In containerized deployments, the blast radius may be limited to the container filesystem, but environment variables, mounted secrets, and application configuration are still at risk. Version 2.13.2 contains a patch for the issue.

It is possible to read the advisory at github.com. This vulnerability is uniquely identified as CVE-2026-26202 since 02/11/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. The technical details are unknown and an exploit is not publicly available. The attack technique deployed by this issue is T1006 according to MITRE ATT&CK.
