CVE-2026-114519 — Missing authorization in the Prospero Flow CRM user API allows a basic role user to read and delete other accounts

Missing Authorization (CWE-862) in the user API of Roskus Prospero Flow CRM from 2.0.0 before 5.26.0 allows a user with a basic role to read the accounts of other users of its own company, including accounts with higher privileges, and, in versions from 3.5.0, to delete them, because the routes GET /api/user/{id} and DELETE /api/user/{id} in routes/api.php carry only the auth:api middleware, which checks that a JSON Web Token is valid and nothing more, and neither UserReadController::read() nor UserDeleteController::delete() checks a permission, a policy or a role before acting. Object access is scoped by company: the read path limits the query to the company of the authenticated user, and the delete path compares the company of the target account with the company of the authenticated user. The delete path skips that comparison when the company of the authenticated user is Company::DEFAULT_COMPANY, so a user with a basic role in that company can delete any account of any company of the installation. Deleting an account removes the data held on it, and the last administrative account of a company can be deleted. This gives the attacker the personal data held on the other accounts, including email address, telephone number, postal address and IBAN, and the ability to delete accounts it has no permission to administer.

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
  • EPSS 0.4% (30-day exploitation probability)+4
  • Technical severity (high)+6

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 (Roskus Prospero Flow CRM).
  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.
