{"id":"CVE-2026-85293","state":"PUBLISHED","title":"InvoicePlane: Stored Cross-Site Scripting (XSS) via Client Email in Invoice and Quote Mailer Forms","description":"InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments. In version 1.7.2-beta-1, InvoicePlane stores client_email values without enforcing email syntax and renders them unescaped inside double-quoted value attributes in the invoice mailer form and quote mailer form. An administrator who can edit a client can store attribute-breaking input, and, when the mailer is configured, JavaScript executes when another authenticated administrator opens the related mailer page. The script runs in the InvoicePlane origin and can perform same-origin actions with the victim's session. This issue is fixed in version 1.7.2.","publishedAt":"2026-09-25T15:29:30.089Z","updatedAt":"2026-09-25T15:59:04.796Z","severity":{"score":4.8,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["InvoicePlane InvoicePlane"],"affected":[{"vendor":"InvoicePlane","product":"InvoicePlane","versions":[{"version":"< 1.7.2","status":"affected"}]}],"references":["https://github.com/InvoicePlane/InvoicePlane/security/advisories/GHSA-477r-xmgc-vcvj","https://github.com/InvoicePlane/InvoicePlane/pull/1635","https://github.com/InvoicePlane/InvoicePlane/commit/1e74c032ff1c65e6a4f9d173505f415c3a539f57","https://github.com/InvoicePlane/InvoicePlane/releases/tag/v1.7.2"],"weaknesses":["CWE-79","CWE-87"],"ingestedAt":"2026-10-29T20:13:15.269Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/85xxx/CVE-2026-85293.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-85293","state":"PUBLISHED","datePublished":"2026-09-25T15:29:30.089Z","dateUpdated":"2026-09-25T15:59:04.796Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-09-03T16:37:49.262Z"},"containers":{"cna":{"title":"InvoicePlane: Stored Cross-Site Scripting (XSS) via Client Email in Invoice and Quote Mailer Forms","descriptions":[{"lang":"en","value":"InvoicePlane is a self-hosted open source application for managing invoices, clients, and payments.
