CVE-2026-26202 — Penpot has Arbitrary File Read via create-font-variant RPC endpoint
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.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- EPSS 0.6% (30-day exploitation probability)+7
- Technical severity (high)+6
- Automatable exploitation (SSVC)+3
The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).
Triage
Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
CISA SSVC assessment CISA
Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.
- Documented patch — github.com (NIST National Vulnerability Database)
First 24 hours
Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.
- Identify exposed assets running the affected vendor/product/version combinations (Kaleidos Penpot, Penpot Penpot).
- The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
- Apply the fixed version or the patch documented under Remediation.
- Search available logs for exploit probes matching the vulnerability class (file handling), errors and authentication anomalies.

Detection
Read off the CVSS vector and the weakness class. Starting points, not tested rules.
- Prioritize edge telemetry for the network-reachable component (proxy, WAF, IDS/IPS).
- Monitor file creation in web directories and paths with traversal sequences (../).

What should defenders know first?
CVE-2026-26202 is "Penpot has Arbitrary File Read via create-font-variant RPC endpoint", rated High. It affects Penpot (Kaleidos); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 7.5 describes technical severity. EPSS 0.58% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
