CVE-2026-107825 corazawaf CVE debrief

Who should care

Defenders using OWASP Coraza WAF in non-net/http integrations should verify exposure and apply version 3.8.0 or later. This includes operators of web applications protected by Coraza WAF, security teams responsible for vulnerability management, and platform administrators who integrate Coraza WAF with custom or third-party components. Prioritizing verification and updates will help mitigate the defense-in-depth bypass issue and reduce the risk of potential

Why it matters

A defense-in-depth bypass issue exists in OWASP Coraza WAF versions 3.0.0 through 3.8.0, potentially allowing attackers to bypass rules targeting query parameters in non-net/http integrations. Defenders should prioritize verifying exposure and applying version 3.8.0 or later.

• Verify exposure in non-net/http integrations
• Potential bypass of rules targeting query parameters
• Prioritize updating to version 3.8.0 or later
• Monitor for potential bypass attempts

Technical summary

OWASP Coraza WAF versions 3.0.0-3.8.0 have a defense-in-depth bypass issue. When ProcessURI fails to parse a URI, it retains the raw URI but omits query parameters, potentially allowing attackers to bypass rules targeting those variables in non-net/http integrations. This issue arises from the library's handling of malformed URI requests, which can be exploited by unauthenticated attackers. The bundled coraza/v3/http integration is not affected because Go net/http rejects such malformed request targets before calling Coraza.

Defensive priority

Defenders should prioritize verifying exposure in non-net/http integrations using Coraza WAF versions 3.0.0-3.8.0 and applying version 3.8.0 or later.

Recommended defensive actions

• Verify Coraza WAF version and update to 3.8.0 or later if using a non-net/http integration
• Review non-net/http integrations for potential exposure to the defense-in-depth bypass
• Monitor for potential bypass attempts in non-net/http integrations
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
