Prior to 3.7.2, isAcceptedUrl() in packages/renderer/htmlUtils.ts uses an unanchored regular expression for internal resource URLs, allowing a javascript: URL containing a matching 32-character path fragment to pass validation and be emitted into an HTML note's link. A low-privileged Joplin Server user can publish the crafted HTML note as a public share. In the current build, ordinary left-click is blocked; demonstrated execution requires middle-click or Open in new tab in an older or non-hardened browser because current Chrome and Firefox block javascript: new-tab navigation. When execution succeeds, the script runs in the Joplin Server origin, can read page-visible content, and can make authenticated same-origin requests when the victim is signed in. This issue is fixed in version 3.7.2.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:C/C:L/I:L/A:N","score":4.4},"cwes":["CWE-79"],"references":["https://github.com/laurent22/joplin/commit/9fdc2d4adbd7b7326a2d0dcc32e12b705bfc285e","https://github.com/laurent22/joplin/pull/15435","https://github.com/laurent22/joplin/security/advisories/GHSA-x9vj-jrqf-9wcm","https://github.com/laurent22/joplin/security/advisories/GHSA-x9vj-jrqf-9wcm"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-46650","score":0.00281,"percentile":0.20632,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
