By \nusing URL-encoded characters such as “%2e” (representing a dot), an \nattacker can manipulate the portion of the URL following the top-level \ndomain (TLD). If a similar, registerable TLD exists (for example, if \n“.com” is the application’s domain, and “.company” is available for \nregistration), an attacker can craft a URL to redirect users to a \nmalicious “.company” domain. By using URL-encoded line feeds, it becomes\n possible to insert arbitrary response headers in the server's HTTP \nresponse.\n\n\n\n\n\n\nThis issue affects TeamDavid before Rollout 528.\n\nStarting with Rollout 528 (June 30, 2026), the affected functionality is disabled by default and the vulnerabilities are therefore no longer exposed through this functionality.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N","score":5.3},"cvss_v3":null,"cwes":["CWE-601"],"references":["https://chayns.net/77892-10814/tapp/763210?postId=11454","https://labs.infoguard.ch/posts/22-cves-in-david-a-secure-m365-alternative/"],"products":[],"source":"nvd","synced_at":"2026-10-24T16:53:34.184483516+00:00"},"epss":{"cve":"CVE-2026-12071","score":0.00458,"percentile":0.39475,"date":"2026-10-25"},"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).
