CVE-2026-108581

TencentCloud Octop through 1.0.2b6 contains a missing authorization vulnerability that allows authenticated low-privileged users to read stored provider API keys via GET /api/providers and GET /api/voice/providers. Attackers can query these endpoints, which only validate the JWT, to obtain plaintext LLM and voice provider API keys and abuse the upstream provider accounts.
