How to Fix CVE-2026-22777

To remediate this vulnerability, upgrade all affected Comfy cli dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

comfy-cli fixed: 4.0.5 
pip install comfy-cli>=4.0.5
comfy-cli fixed: 3.39.2 
pip install comfy-cli>=3.39.2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

pip show comfy-cli

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2026-22777, inspect your installed packages using pip:

pip show comfy-cli

Analyze the terminal output to locate any version of Comfy cli in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.0.5), your application is affected.

Note: The pip show comfy-cli command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-93: Improper Neutralization of CRLF Sequences ('CRLF Injection'), where the product uses crlf (carriage return line feeds) as a special element, e.g. to separate lines or records, but it does not neutralize or incorrectly neutralizes crlf sequences from inputs. In Comfy cli, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

## 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 ## References - [CWE-93: Improper Neutralization of CRLF Sequences](https://cwe.mitre.org/data/definitions/93.html) - [OWASP CRLF Injection](https://owasp.org/www-community/vulnerabilities/CRLF_Injection) ## Credit This vulnerability was reported by: - 李存义 <xiaoheihei1107@gmail.com> - D0n9 Li <wyd0n9@gmail.com> - Swings <swing@mail.exp.sh> - Osword from SGLAB of Legendsec at Qi'anxin Group <zhzhdoai@gmail.com>
