Security readout for executives and security teams
Plain-English summary
CVE-2026-22777 lets an unauthenticated remote attacker tamper with ComfyUI-Manager configuration by injecting special characters through HTTP query parameters. The result is arbitrary values being added to config.ini, potentially weakening security settings or changing application behavior. Patched versions are available.
Executive priority
Prioritize remediation for any network-accessible ComfyUI-Manager instance. This is a high-severity integrity issue with available patches and no user interaction requirement. Treat it as a configuration-tampering risk rather than confirmed data theft or active ransomware activity.
Technical view
ComfyUI-Manager before 3.39.2 and versions 4.0.0 through 4.0.4 are affected by CRLF injection in a configuration handler. The advisory maps this to CWE-93 and CVSS 3.1 score 7.5: AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N, indicating high integrity impact without required authentication or user interaction.
Likely exposure
Exposure is most relevant where ComfyUI-Manager is reachable over a network, especially if administrative or extension-management endpoints are exposed beyond trusted users. The sources do not specify default exposure, deployment patterns, or whether ComfyUI itself is internet-facing.
Exploitation context
The CVE record states the issue can be triggered through HTTP query parameters and does not require privileges or user interaction. The provided sources do not state active exploitation, and the CVE is not listed as KEV in the bundle.
Researcher notes
The core issue is CRLF injection leading to arbitrary config.ini entries. Public sources identify the vulnerable component, affected version ranges, CWE-93, CVSS vector, and fixing commit. They do not provide evidence of exploitation in the wild or additional product impact.
Mitigation direction
- Upgrade ComfyUI-Manager to 3.39.2 or 4.0.5, depending on the installed branch.
- If immediate upgrade is not possible, check vendor guidance for supported temporary controls.
- Restrict network access to ComfyUI-Manager to trusted users and management networks.
- Review config.ini for unexpected security or behavior-changing settings after remediation.
Validation and detection
- Inventory ComfyUI-Manager installations and record installed versions.
- Flag versions below 3.39.2 and 4.0.0 through 4.0.4 as affected.
- Confirm patched version is 3.39.2 or 4.0.5 after update.
- Review application configuration for unauthorized or unusual entries.
- Monitor vendor advisory and repository for any follow-up guidance.

Improper Neutralization of CRLF Sequences ('CRLF Injection')
Improper Neutralization of CRLF Sequences ('CRLF Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
