- Severity: CVSS 5.1 (Medium), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2025-10-02 · Updated: 2025-10-02

## Affected

- Hiberus Sintra: all versions

## Description

Incorrect Cross-Origin Resource Sharing (CORS) configuration in Hiberus Sintra. Cross-Origin Resource Sharing (CORS) allows browsers to make cross-domain requests in a controlled manner. This request has an “Origin” header that identifies the domain making the initial request and defines the protocol between a browser and a server to see if the request is allowed. An attacker can exploit this and potentially perform privileged actions and access confidential information when Access-Control-Allow-Credentials is enabled.
