The vulnerability is reflected by resource exhaustion and potential memory exhaustion weaknesses, as identified by CWE-400 and CWE-770. When triggered, the request leads the application to become unresponsive, disrupting access for all users without compromising data confidentiality or integrity.", "risk_and_exploitability": "The CVSS score of 4.3 indicates moderate severity, and the EPSS score of less than 1% suggests low exploitation probability. The vulnerability is not currently catalogued in the CISA KEV list. It is inferred that the attack vector is a remote HTTP request targeting the media_upload_xhr endpoint; no authentication prerequisites are stated, so a publicly accessible endpoint is likely sufficient. Because the conditions are easily met and the denial of service has wide impact, operators should consider rapid mitigation."}}}}, "created": "2026-04-03T21:17:07.430092+00:00", "title": "Remote Denial of Service via Media Upload in Dokuwiki 2025-05-14b", "updated": "2026-04-09T08:29:19.839954+00:00", "vendors": ["wiki", "wiki$PRODUCT$dokuwiki"]}
