{"id":"CVE-2026-44667","summary":"Faction: Stored XSS in Remediation Verification Attachment Filename Preview Rendering","details":"FACTION is a PenTesting Report Generation and Collaboration Framework. Prior to 1.8.3, Faction is vulnerable to stored cross-site scripting (XSS) via attachment filenames in remediation verification file preview flows. User-supplied filename values are persisted and then rendered into HTML and attribute contexts without output encoding, allowing attacker-controlled JavaScript to execute in the browser of any user who opens the affected verification/remediation views. Because the payload is stored server-side and rendered to other users, exploitation is persistent and can impact privileged accounts. This vulnerability is fixed in 1.8.3.","aliases":["GHSA-x3fm-rrxj-rg66"],"modified":"2026-07-08T08:05:15.913323778Z","published":"2026-05-26T17:42:39.244Z","database_specific":{"cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44667.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/factionsecurity/faction/releases/tag/1.8.3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44667.json"},{"type":"ADVISORY","url":"https://github.com/factionsecurity/faction/security/advisories/GHSA-x3fm-rrxj-rg66"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44667"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/factionsecurity/faction","events":[{"introduced":"0"},{"fixed":"90b341744fb65c4fb916c997533695c6da75e41f"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"1.8.3"}]}}],"versions":["1.8.2","1.7.7","1.7.6","1.7.5","1.7.4","1.7.1","1.7.0","1.6.8","1.6.7","1.6.6","1.6.5","1.6.4","1.6.3","1.6.2","1.6.1","1.6.0","1.5.2","1.5.1","1.5.0","1.4.4","1.4.3","1.4.2","1.4.1","1.4.0","1.3.36","1.3.35","1.3.34","1.3.33","1.3.32","1.3.29","1.3.28","1.3.27","1.3.26","1.3.25","1.3.24","1.3.23","1.3.22","1.3.21","1.3.20","1.3.8","1.3.7","1.3.6","1.3.5","1.3.4","1.3.3","1.3.2","1.3.1","1.3.0","1.2.5","1.2.4","1.2.3","1.2.2","1.2.1","1.2.0","1.1.27","1.1.26.2","1.1.26.1","1.1.26.0","1.1.25.1","1.1.25.0","1.1.25","1.1.24.3","1.1.24.2","1.1.24.1","1.1.24.0","1.1.24","1.1.23","1.1.22","1.1.21","1.1.20","1.1.19","1.1.18","1.1.17","1.1.16","1.1.15","1.1.14","1.1.13","1.1.12","1.1.11","1.1.10","1.1.9","1.1.8","1.1.7","1.1.6","1.1.5","1.1.4","1.1.3","1.1.2","1.1.1","1.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-44667.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:N"}]}
