Operationally, ranked in the top 8.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
CVE-2022-2290 is a reflected cross-site scripting vulnerability (CWE-79) affecting the Trilium note-taking application in the zadam/trilium GitHub repository prior to versions 0.52.4 and 0.53.1-beta. The flaw carries a CVSS 3.1 score of 6.1 with network attack vector, low complexity, no required privileges, and required user interaction, resulting in limited confidentiality and integrity impact with changed scope.
An unauthenticated remote attacker can exploit the issue by supplying a crafted request that is reflected back to a victim user who clicks a malicious link, allowing execution of arbitrary script in the user's browser session within the Trilium application context.
Public references point to specific commits that remediate the flaw and to a coordinated disclosure on huntr.dev; the recommended mitigation is therefore to upgrade to a patched release.
The associated EPSS score has remained flat at 0.0740 with no material increase after disclosure.
