Authentication Bypass in cu silicon

An unauthenticated remote code execution vulnerability (CVE-2026-82919) exists in the cu silicon library versions 0.1.5 and earlier due to missing authentication controls in the create_app function.

CVE search metadata

CVE search record: CVE-2026-82919. Severity: high. CVSS: 7.3. KEV: no. Product: silicon (<= 0.1.5). Brief: Authentication Bypass in cu silicon. Brief link: https://feed.craftedsignal.io/briefs/2026-08-cve-2026-82919/

CVE-2026-82919 describes a critical authentication bypass vulnerability affecting the 'cu silicon' package in versions up to and including 0.1.5. The vulnerability is located within the create_app function inside the views.py file, specifically impacting the edit endpoint. Because the endpoint fails to verify user credentials or authorization tokens, a remote, unauthenticated attacker can interact with the component to manipulate application states or data. The vulnerability has been confirmed with a public exploit, making it accessible for threat actors to target vulnerable implementations. Despite prior notification, the vendor has not provided a security update or remediation guidance, leaving current deployments exposed to unauthorized remote manipulation.

Impact

Successful exploitation allows remote, unauthenticated attackers to bypass security controls in deployments using cu silicon. This could result in unauthorized data access, system manipulation, or further escalation depending on the specific integration of the library within the host environment. The impact is assessed as high due to the lack of required authentication and the availability of public exploits.

Recommendation

Prioritized actions for security teams:

  • Inventory all services or applications utilizing cu silicon version 0.1.5 or earlier.
  • Implement network-level restrictions or Web Application Firewall (WAF) rules to restrict access to endpoints mapped to the vulnerable create_app functionality until a patch is available.
  • Monitor application logs for unauthorized POST or PUT requests targeting edit endpoints associated with the cu silicon package.
  • If a patch is unavailable, consider migrating away from the affected package or implementing a wrapper proxy that enforces authentication before requests reach the vulnerable function.

Immediate actions

Inventory all internal applications using cu silicon version 0.1.5 or lower
