CVE-2026-75928 Overview
The Brushfire platform's video content streaming application exposes internal database path information in HTTP requests. A remote, unauthenticated attacker can leverage this exposure to read information about other users of the platform. The issue is classified under CWE-497: Exposure of Sensitive System Information to an Unauthorized Control Sphere. Brushfire remediated the flaw in February 2026. The vulnerability affects the hosted service at Brushfire Online, so no customer-side patch is required.
Critical Impact
Unauthenticated remote attackers can enumerate and read information about other Brushfire platform users through exposed database path data.
Affected Products

Technical Details for CVE-2026-75928
Vulnerability Analysis
The Brushfire video streaming application transmits database path information within request data sent to clients. This exposure allows a remote attacker to derive references that identify records belonging to other users. Because the endpoint requires no authentication, the attacker can iterate over exposed identifiers and retrieve information about arbitrary accounts on the platform. The weakness is categorized under [CWE-497], which covers unnecessary exposure of internal system details to actors outside the intended trust boundary.
Root Cause
The application embeds internal database path values in outbound request or response data instead of using opaque, access-controlled references. This design decision leaks structural information that should remain server-side. When combined with missing authorization checks on the affected endpoint, the exposed paths become a direct primitive for reading data belonging to other users.
Attack Vector
An attacker interacts with the public streaming application over the network without credentials or user interaction. By observing legitimate traffic to the platform, the attacker recovers the database path pattern. The attacker then crafts modified requests referencing other users' identifiers and receives information that should be restricted to the account owner. No local access, elevated privileges, or social engineering is required.
No public exploit code is available. See the CISA CSAF Vulnerability Report and the CVE-2026-75928 Record for authoritative technical details.
Detection Methods for CVE-2026-75928
Indicators of Compromise
- Repeated unauthenticated requests to online.brushfire.com endpoints that vary only in embedded identifier or path parameters.
- Response payloads containing internal database path fragments returned to clients.
- Anomalous enumeration patterns where a single source cycles sequential identifiers against the streaming application.
Detection Strategies
- Inspect application and web-tier logs for high-volume access to streaming endpoints from a single client without corresponding authenticated session activity.
- Alert on responses that echo internal path-like strings, which indicate the exposure primitive is present in traffic.
- Correlate client IPs performing identifier enumeration with subsequent access to records they do not own.
Monitoring Recommendations
- Enable full HTTP request and response logging on the affected endpoints during the exposure window before the February 2026 fix.
- Baseline normal per-user request rates for the streaming application and alert on deviations consistent with enumeration.
- Monitor for unusual referrer, user-agent, or geographic patterns issuing unauthenticated requests to user-scoped resources.
How to Mitigate CVE-2026-75928
Immediate Actions Required
- Confirm you are using the current production version of Brushfire Online, which incorporates the February 2026 fix.
- Review platform audit logs, if available from Brushfire, for suspicious enumeration or unauthenticated data reads prior to the fix date.
- Rotate any user-provided secrets or notify affected users if evidence of data exposure is discovered.
Patch Information
Brushfire remediated CVE-2026-75928 in February 2026 as an update to the hosted service. Because the affected component is Software-as-a-Service, no customer-managed patch deployment is required. Verification is available through the CVE-2026-75928 Record and the CISA CSAF Vulnerability Report.
Workarounds
- No customer-side workaround exists; the fix is delivered by the vendor to the hosted platform.
- Organizations should validate that traffic to online.brushfire.com no longer returns database path fragments in responses.
- Restrict integrations that consume Brushfire APIs so that internal identifiers are not logged or forwarded to downstream systems.
