CVE-2026-71271 Memos Webhook SSRF via 0.0.0.0 Reserved-IP Bypass

Memos' webhook URL validation, isReservedIP internal/webhook/validate.go, checks a candidate IP against a reservedCIDRs list that omits 0.0.0.0/8 and never calls ip.IsUnspecified — unlike the correctly implemented sibling function isInternalIP in internal/httpgetter/htmlmeta.go, which does...

CVE-2026-54635

CVE-2026-54635 affects pytonapi 2.0.0–2.2.0, where TonapiWebhookDispatcher fails to validate the Authorization header for webhook handlers registered with a documented path (custom path).

The User Registration & Membership WordPress plugin before 5.2.2 does not verify the authenticity of incoming payment-provider webhook notifications before acting on them, allowing unauthenticated attackers to forge a payment-approved event and activate a paid membership subscription without...

Fission: Environment Runtime.Container and Builder.Container SecurityContext bypass allows privileged pod creation

Summary A follow-up bypass of the round-4 PodSpec hardening GHSA-gx55-f84r-v3r7, GHSA-wmgg-3p4h-48x7, GHSA-v455-mv2v-5g92. Those advisories validate and sanitize the PodSpec spec.runtime.podSpec / spec.builder.podSpec / function.spec.podSpec, but the Environment CRD also exposes...

Fission Environment CRD PodSpec Injection Leading to Node Escape and Cluster Takeover

Summary A stronger framing of the same root cause as GHSA-gx55-f84r-v3r7: the Environment.spec.runtime.podSpec / spec.builder.podSpec passthrough lacked validation, and MergePodSpec propagated dangerous fields into the generated pods. Details Three independent flaws compounded: 1. Validate gap...
