The chosen value was not sufficiently sanitized before processing it at the user interface, allowing for indirect cross-site scripting attacks. Accounts that were temporarily taken over could be configured to trigger persistent code execution, allowing an attacker to build a foothold. Sanitization is in place for product names now. No publicly available exploits are known.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","score":5.4},"cwes":["CWE-79"],"references":["https://documentation.open-xchange.com/appsuite/security/advisories/csaf/2023/oxas-adv-2023-0004.json","https://software.open-xchange.com/products/appsuite/doc/Release_Notes_for_Patch_Release_6243_7.10.6_2023-08-01.pdf","https://documentation.open-xchange.com/appsuite/security/advisories/csaf/2023/oxas-adv-2023-0004.json","https://software.open-xchange.com/products/appsuite/doc/Release_Notes_for_Patch_Release_6243_7.10.6_2023-08-01.pdf"],"products":["open-xchange:ox_guard"],"source":"nvd","synced_at":"2026-10-19T21:40:11.519948003+00:00"},"epss":{"cve":"CVE-2023-26456","score":0.00383,"percentile":0.32428,"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).
