A CORS misconfiguration in Jan up to version 0.8.4 allows network-adjacent attackers to bypass trusted host restrictions when the server is bound to 0.0.0.0, enabling unauthorized access to the OpenAI-compatible API for model enumeration, inference, and MCP tool invocation. A publicly available exploit exists, and CISA KEV does not list active exploitation; EPSS score is low at 0.19%, indicating limited real-world exploitation risk.
An arbitrary file upload vulnerability in the /v1/app/appendFileSync interface of Jan v0.4.12 allows attackers to execute arbitrary code via uploading a crafted file. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
An arbitrary file upload vulnerability in the /v1/app/writeFileSync interface of Jan v0.4.12 allows attackers to execute arbitrary code via uploading a crafted file. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Jan v0.4.12 was discovered to contain an arbitrary file read vulnerability via the /v1/app/readFileSync interface. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
