CVE-2026-86185: Improper Certificate Validation in Bilibili Bilibili Desktop
Description
Bilibili Desktop versions up to 1.18.0 disable TLS certificate verification globally and execute unsigned remote JavaScript configurations without integrity checks. This allows an attacker positioned on the network path to intercept configuration fetches and inject arbitrary JavaScript. The injected code runs with access to privileged IPC bridges, enabling execution of system commands or theft of login credentials.

Technical Analysis
CVE-2026-86185 affects Bilibili Desktop through version 1.18.0 by disabling TLS certificate verification process-wide and executing unsigned remote JavaScript configuration without integrity validation. An attacker with network access can intercept configuration requests, inject malicious JavaScript that executes in the renderer process with privileged IPC bridge access, potentially leading to system command execution or credential theft.
Potential Impact
An attacker in a man-in-the-middle position can exploit this vulnerability to execute arbitrary code with elevated privileges on the affected system or steal sensitive user credentials. This compromises confidentiality, integrity, and availability of the affected system and user data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, avoid using affected versions in untrusted networks or restrict network access to trusted environments to reduce exposure.
