CVE-2026-111323 samugit83 CVE debrief

Who should care

Defenders responsible for RedAmon instances, especially those with internet-facing /tradecraft/verify endpoints, should assess potential exposure and internal network risks. This includes reviewing current configurations, verifying instance accessibility, and coordinating with security teams to prioritize remediation. Additionally, operators of RedAmon instances should evaluate the vulnerability's impact on their specific environments and take steps to rem

Why it matters

CVE-2026-111323 is a medium-severity vulnerability in RedAmon that allows unauthenticated server-side request forgery. Defenders should prioritize verifying exposure, especially for internet-facing instances, and assess potential internal network risks. Evidence is limited, and further verification is required to determine exploitation, impact, and remediation.

• Potential exposure of cloud metadata services through SSRF
• Possible internal network exposure through DNS rebinding or redirects
• Need for verification of RedAmon instance exposure and endpoint accessibility
• Potential for unauthorized access to internal resources

Technical summary

The vulnerability exists in the agent POST /tradecraft/verify endpoint of RedAmon through version 7.0.1. The validate_url function only checks the initial hostname, allowing attackers to submit public URLs that redirect or DNS-rebind to internal addresses, potentially exposing cloud metadata services. This could lead to unauthorized access to internal resources and sensitive information. The vulnerability is a result of insufficient validation of URLs, which enables attackers to bypass security checks and interact with internal systems.

Defensive priority

Defenders should prioritize verifying exposure of RedAmon instances, especially those with internet-facing /tradecraft/verify endpoints, and assess potential internal network exposure through SSRF.

Recommended defensive actions

• Verify exposure of RedAmon instances, especially those with internet-facing /tradecraft/verify endpoints
• Assess potential internal network exposure through SSRF
• Restrict access to the /tradecraft/verify endpoint
• Monitor for suspicious activity related to the /tradecraft/verify endpoint
• Perform vulnerability scanning for RedAmon instances
• Review and update incident response plans for potential SSRF attacks
• Implement additional logging and monitoring for /tradecraft/verify endpoint activity

Evidence notes

The CVE record and source item provide details on the vulnerability, including its existence in RedAmon through version 7.0.1 and the specific endpoint affected. However, details on exploitation, impact, and remediation are limited.
