CVE-2026-76245: Insufficient Verification of Data Authenticity

stigmem pip package stigmem-node version 0.9.0a1 contains a timestamp-handling mismatch in federation peer-token validation that can cause valid peer tokens to be incorrectly treated as expired. This affects the availability and reliability of authenticated federation flows on nodes using...

CVE-2026-76244: Cleartext Transmission of Sensitive Information

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...

CVE-2026-76242: Improper Certificate Validation

stigmem-node 0.9.0a1 accepts federation peer key material during peer registration without a separate administrator out-of-band fingerprint approval step. On nodes that accept federation peer registration over a network where initial registration can be intercepted or misdirected, an attacker can...

CVE-2026-76241: Download of Code Without Integrity Check

stigmem-node 0.9.0a1 allows plugin signature enforcement to be disabled via a single configuration flag without a second explicit acknowledgment. If that setting is carried into an environment where plugin directories are writable by less-trusted users, unsigned potentially malicious plugin code...

CVE-2026-76239: Server-Side Request Forgery (SSRF)

Stigmem before 0.9.0a11 fails to validate the deliveryaddress parameter when creating webhook subscriptions, allowing authenticated users to specify internal loopback and private network destinations. Attackers can trigger matching fact-change events to cause the Stigmem server to issue server-si...

CVE-2026-76237: Authorization Bypass Through User-Controlled Key

stigmem-node before 0.9.0a12 contains a broken object level authorization cross-tenant BOLA vulnerability in the quarantine review endpoints. On multi-tenant deployments running the opt-in stigmem-plugin-multi-tenant, the list/count queries and getquarantinedfact in routes/quarantine.py lacked a...

CVE-2026-76238: Incorrect Authorization

stigmem versions before 0.9.0a12 contain a broken object level authorization vulnerability in the decay sweep endpoint that allows authenticated attackers with write credentials for one tenant to execute decay operations affecting all tenants. Attackers can submit POST requests to the decay sweep...

CVE-2026-76243: Improper Authorization

stigmem versions before 0.9.0a2 allow unauthenticated access when authentication is disabled on non-loopback deployments. Attackers can perform read, write, and federation operations with anonymous identity when nodes are exposed outside local development environments...

CVE-2026-76236: Authorization Bypass Through User-Controlled Key

stigmem-node before 0.9.0a12 contains a cross-tenant broken object level authorization BOLA flaw in the RTBF right-to-be-forgotten tombstone mechanism. issuetombstone defaulted the tenant to "default" instead of the caller's tenant, allowing deletion records to be written to the wrong tenant, and...

Overview stigmem-node is a Stigmem reference node — single-host production implementation Affected versions of this package are vulnerable to Incorrect Authorization in the rundecaysweep process. An attacker can access or modify data belonging to other tenants by initiating a decay sweep with a...

stigmem-node: decay sweep expires and counts facts across all tenants (cross-tenant BOLA)

Summary On a multi-tenant stigmem node, a caller holding a write credential for one tenant can run a decay sweep that acts on every tenant's facts.
