CVE-2026-76244: Cleartext Transmission of Sensitive Information in eidetic-labs stigmem
stigmem-node contains an insecure default configuration vulnerability that allows federation traffic to traverse networks without mTLS protection when non-loopback endpoints are enabled. Operators who explicitly disabled mTLS while binding federation to non-loopback addresses expose federation traffic to cleartext interception and man-in-the-middle attacks.
AI Analysis
Technical Summary
CVE-2026-76244 describes a vulnerability in the stigmem-node component of eidetic-labs' stigmem product. The issue arises when operators disable mutual TLS (mTLS) while binding federation traffic to non-loopback network addresses. This configuration causes federation traffic to traverse networks without encryption, exposing it to interception and man-in-the-middle attacks. The vulnerability is due to an insecure default configuration that does not enforce mTLS on non-loopback endpoints, leading to cleartext transmission of sensitive information.
Potential Impact
Sensitive federation traffic can be intercepted or altered by attackers due to the lack of mTLS protection when non-loopback endpoints are used without mTLS enabled. This compromises confidentiality and integrity of the transmitted data, potentially allowing man-in-the-middle attacks.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, operators should ensure that mTLS is enabled when binding federation traffic to non-loopback endpoints to prevent cleartext transmission. Avoid disabling mTLS in such configurations.
