CVE-2026-76244: Cleartext Transmission of Sensitive Information in eidetic-labs stigmem
Description
stigmem-node in eidetic-labs stigmem has a vulnerability where federation traffic can be transmitted without mTLS protection if non-loopback endpoints are enabled and mTLS is explicitly disabled. This insecure default configuration allows sensitive federation traffic to be exposed in cleartext, risking interception and man-in-the-middle attacks.

Technical Analysis
CVE-2026-76244 describes an insecure default configuration in eidetic-labs stigmem's stigmem-node component. When operators disable mutual TLS (mTLS) while binding federation services to non-loopback network addresses, federation traffic is transmitted without encryption. This cleartext transmission exposes the traffic to interception and man-in-the-middle attacks. The vulnerability affects versions from 0 up to but not including 0.9.0a2. The CVSS 4.0 score is 9.1, indicating a critical severity with network attack vector, low attack complexity, no privileges required, and high impact on confidentiality and integrity.
Potential Impact
Federation traffic can be intercepted or altered by attackers due to lack of mTLS encryption when non-loopback endpoints are used and mTLS is disabled. This compromises confidentiality and integrity of sensitive information transmitted between federated nodes.
Mitigation Recommendations
Operators should ensure mTLS is enabled when binding federation to non-loopback addresses to protect federation traffic. Upgrading to version 0.9.0a2 or later, where this issue is presumably fixed, is recommended. Patch status is not explicitly confirmed; check vendor advisories for updates.
