{"id":"CVE-2026-27116","summary":"Vikunja has Reflected HTML Injection via filter Parameter in Projects Module","details":"Vikunja is an open-source self-hosted task management platform. Prior to version 2.0.0, a reflected HTML injection vulnerability exists in the Projects module where the `filter` URL parameter is rendered into the DOM without output encoding when the user clicks \"Filter.\" While `\u003cscript\u003e` and `\u003ciframe\u003e` are blocked, `\u003csvg\u003e`, `\u003ca\u003e`, and formatting tags (`\u003ch1\u003e`, `\u003cb\u003e`, `\u003cu\u003e`) render without restriction — enabling SVG-based phishing buttons, external redirect links, and content spoofing within the trusted application origin. Version 2.0.0 fixes this issue.","aliases":["GHSA-4qgr-4h56-8895","GO-2026-4552"],"modified":"2026-04-10T05:38:20.493484Z","published":"2026-02-25T21:33:50.448Z","related":["SUSE-SU-2026:1042-1"],"database_specific":{"cwe_ids":["CWE-79","CWE-80"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/27xxx/CVE-2026-27116.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://vikunja.io/changelog/vikunja-v2.0.0-was-released"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/27xxx/CVE-2026-27116.json"},{"type":"ADVISORY","url":"https://github.com/go-vikunja/vikunja/security/advisories/GHSA-4qgr-4h56-8895"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27116"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/go-vikunja/vikunja","events":[{"introduced":"0"},{"fixed":"25268530e4a81d69708d1b123b63e9193497f431"}]}],"versions":["v0.1","v0.10","v0.11","v0.12","v0.13","v0.14.0","v0.15.0","v0.16.0","v0.17.0","v0.18.0","v0.18.1","v0.19.0","v0.19.1","v0.19.2","v0.2","v0.20.0","v0.20.1","v0.20.3","v0.20.4","v0.21.0","v0.22.0","v0.22.1","v0.23.0","v0.24.1","v0.3","v0.4","v0.5","v0.6","v0.7","v0.8","v0.9","v1.0.0","v1.0.0-rc0","v1.0.0-rc1","v1.0.0-rc2","v1.0.0-rc3","v1.0.0-rc4","v1.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-27116.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
