Raw vector
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:NCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2026-22558 is a high-severity Improper Neutralization of Special Elements in Data Query Logic (CWE-943) vulnerability in Ui (inferred from references). Its CVSS base score is 7.7 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 44th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-22558 is an authenticated NoSQL injection vulnerability (CWE-943) in the UniFi Network Application. Published on 2026-03-19T15:16:23.697, it carries a CVSS v3.1 base score of 7.7 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N). The flaw enables a malicious actor with authenticated network access to escalate privileges through improper handling of NoSQL queries.
An attacker requires low privileges (PR:L) and authenticated access to the network to exploit this vulnerability remotely (AV:N) with low attack complexity (AC:L) and no user interaction (UI:N). Exploitation changes scope (S:C), yielding high confidentiality impact (C:H) via privilege escalation, potentially exposing sensitive data without integrity or availability disruption.

Security testing in development catches injection vulnerabilities before release but does not itself implement the fix.
Secure development life cycle mandates input validation and query parameterization that directly prevent injection flaws.
Application security requirements explicitly call for controls against injection and improper query construction.
Secure architecture principles reduce the likelihood of query-logic flaws but do not prescribe the specific coding practice.
Secure coding standards require proper neutralization of special elements in all data queries.
Outsourced development agreements can require secure coding practices, indirectly mitigating the weakness.
