CVE-2026-86185
Bilibili Desktop through 1.18.0 disables TLS certificate verification process-wide and executes unsigned remote JavaScript configuration without integrity checks.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.11%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Bilibili Desktop through 1.18.0 disables TLS certificate verification process-wide and executes unsigned remote JavaScript configuration without integrity checks. An attacker in an on-path network position can intercept configuration fetches, inject arbitrary JavaScript executed in the renderer with access to the privileged IPC bridge, and execute system commands or steal login credentials.
