Description
Impact
Vulnerability Type: CRLF Injection via ConfigParser
An attacker can inject special characters into HTTP query parameters to add arbitrary configuration values to the `config.ini` file. This can lead to security setting tampering or modification of application behavior.
Affected Users: Users running ComfyUI-Manager in environments where ComfyUI is configured with the `--listen` option to allow remote access.
CVSS Score: 7.5 (High)
Patches
Fixed in the following versions:
• 3.39.2 (v3.x branch)
• 4.0.5 (v4.x branch)
Sanitization logic was added to the `write_config()` function to remove CRLF and NULL characters from all string values.
Workarounds
If upgrading is not possible:
• Run ComfyUI-Manager only on trusted networks
• Block external access via firewall
• Run on localhost only without the `--listen` option
