CVE-2026-3189 — feiyuchuixue sz-boot-parent download server-side request forgery

A weakness has been identified in feiyuchuixue sz-boot-parent up to 1.3.2-beta. This vulnerability affects unknown code of the file /api/admin/common/files/download. Executing a manipulation of the argument url can lead to server-side request forgery. The attack can be executed remotely. Attacks of this nature are highly complex. It is stated that the exploitability is difficult. Upgrading to version 1.3.3-beta is able to resolve this issue. This patch is called aefaabfd7527188bfba3c8c9eee17c316d094802. Upgrading the affected component is advised. The project was informed beforehand and acted very professional: "We have added a URL protocol whitelist validation to the file download interface, allowing only http and https protocols."

Low

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
CISA SSVC: exploitation "poc"+5

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.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.
