Attackers can pass id[1] with crafted SQL, such as time-based SLEEP payloads, along with an api_key derived from md5(home_url()), which flows unsanitized into Database::get_where_query to extract database contents. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-18.\n\n## Affected\n\n- `NotificationX >= 2.0.0 < 2.3.12`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":45,"depthScoreParts":{"impact":45.1,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
