CVE-2026-111604 — eladmin through 2.7 Broken Access Control via /api/users Update and Delete

eladmin through 2.7 contains an authorization bypass vulnerability that allows department-scoped user managers to modify or delete accounts outside their data scope because write handlers skip department checks. Attackers with user:edit or user:del permissions can send PUT or DELETE requests to /api/users with target user ids to disable, reassign, alter, or delete accounts in other departments.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • No scoring signals.

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Elunez Eladmin).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Search available logs for exploit probes matching the vulnerability class (access control), errors and authentication anomalies.
