CVE-2026-76244

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-2026-76239

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...

EUVD-2026-62409

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 stigmem-node Insecure Federation Transport Configuration

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...

EUVD-2026-62407

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...

EUVD-2026-62406

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...

EUVD-2026-62405

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-2026-76241

stigmem-node 0.9.0a1 lets an operator disable plugin signature enforcement via a single configuration flag without confirmation. If plugin directories are writable by less-trusted users, unsigned malicious plugins can be loaded, causing arbitrary code execution. Upgrade to 0.9.0a2, which requires...

EUVD-2026-62404

stigmem-node 0.9.0a1 interpolates Postgres backend schema identifiers into SQL strings without defensive quoting. In the affected code path the schema value is operator-controlled, but the unsafe pattern could allow SQL injection if a schema name were derived from tenant, request, or user input...

CVE-2026-76239 Stigmem before 0.9.0a11 SSRF via unvalidated webhook delivery_address

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-2026-76239

Stigmem versions before 0.9.0a11 do not validate the delivery_address parameter in webhook subscription creation, enabling authenticated users to force the server to send POST requests to internal services (loopback/private network), achieving blind SSRF. Remediation: upgrade to 0.9.0a11 or later...

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...

EUVD-2026-62478

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-2026-76238

stigmem before 0.9.0a12 has a BOLA flaw in the decay sweep endpoint. Authenticated attackers with write access to one tenant can POST with ttl_seconds=0 to expire facts across all tenants, or use dry_run to retrieve cross-tenant fact counts and existence data. CVSS 4.0 scores 7.2 HIGH (integrity ...

CVE-2026-76237

stigmem-node before 0.9.0a12 has a cross-tenant BOLA flaw in quarantine review endpoints: list/count queries and _get_quarantined_fact in routes/quarantine.py lack a tenant_id predicate, and the garden lookup is not tenant-scoped, allowing a low-privilege tenant admin to read, admit, or reject ot...

EUVD-2026-62476

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...

EUVD-2026-62477

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...

GHSA-6GQW-JQV7-V88M 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. The candidate-selection queries in lifecycle/decay.py selectttlcandidates, selectconfidencecandidates carried no tenantid predicate, and the caller's...

GHSA-XHV3-Q4XX-349R stistigmem-node: quarantine review surface exposes and mutates other tenants' quarantined facts (cross-tenant BOLA)

Summary On a multi-tenant stigmem node, a tenant administrator could list, read, and admit or reject quarantined facts belonging to other tenants. The list/count queries and getquarantinedfact in routes/quarantine.py lacked an f.tenantid = identity.tenantid predicate, and the garden lookup was no...
