{"id":"CVE-2026-45805","summary":"Penpot: MCP REPL server binds to 0.0.0.0 with unauthenticated /execute endpoint — RCE","details":"Penpot is an open-source design tool for design and code collaboration. Prior to 2.15.0, Penpot MCP's mcp/packages/server/src/ReplServer.ts bound the ReplServer to 0.0.0.0:4403 and exposed an unauthenticated /execute endpoint that passed the code field to PluginBridge.executePluginTask(), allowing anyone on the network to execute JavaScript on the server. This issue is fixed in version 2.15.0.","aliases":["GHSA-22qr-rp27-j9wm"],"modified":"2026-07-17T03:46:45.274168739Z","published":"2026-07-15T15:11:22.168Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45805.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-749"]},"references":[{"type":"WEB","url":"https://github.com/penpot/penpot/releases/tag/2.15.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/45xxx/CVE-2026-45805.json"},{"type":"ADVISORY","url":"https://github.com/penpot/penpot/security/advisories/GHSA-22qr-rp27-j9wm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-45805"},{"type":"REPORT","url":"https://github.com/penpot/penpot/issues/9518"},{"type":"FIX","url":"https://github.com/penpot/penpot/commit/798ee46b4a84ee6dfc756b001f33acbe0280d62f"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/penpot/penpot","events":[{"introduced":"0"},{"fixed":"798ee46b4a84ee6dfc756b001f33acbe0280d62f"},{"fixed":"bd3ca6f8e56869a18731544099c35bd4ab2824b6"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"2.15.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["2.15.0-RC10","2.15.0-RC9","2.15.0-RC8","2.15.0-RC7","2.15.0-RC6","2.15.0-RC5","2.15.0-RC4","2.14.4","2.15.0-RC3","2.14.5-RC2","2.14.5-RC1","2.14.3","2.14.3-RC1","2.14.2","2.14.1","2.14.1-RC1","2.14.0","2.14.0-RC5","2.14.0-RC4","2.14.0-RC3","2.14.0-RC2","2.14.0-RC1","2.10.0-RC1","2.7.0-RC1","2.6.0-RC1","2.5.0-RC1","2.5.0-DEV","pre-lazy-loading","1.14.1-beta","1.14.0-beta","1.9.0-alpha","1.8.2-alpha","1.8.1-alpha","1.8.0-alpha","1.7.4-alpha","1.7.3-alpha","1.7.2-alpha","1.7.1-alpha","1.7.0-alpha","1.6.5-alpha","1.6.4-alpha","1.6.3-alpha","1.6.2-alpha","1.6.1-alpha","1.6.0-alpha","1.5.4-alpha","1.5.3-alpha","1.5.2-alpha","1.5.1-alpha","1.5.0-alpha","1.4.1-alpha","1.4.0-alpha","1.4.0-dev","1.3.0-alpha","1.2.0-alpha","1.1.0-alpha","1.0.0-alpha","0.1.0","0.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-45805.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
