Cisco Talos has observed an ongoing malware campaign that seeks to infect victims with a multi-stage malware framework, implemented in PowerShell and C#, which we are referring to as “PS1Bot.”

Talos reported 5 vulnerabilities to Broadcom and Dell affecting both the ControlVault3 Firmware and its associated Windows APIs that we are calling “ReVault”.

A new report by VulnCheck exposes a critical command injection flaw (CVE-2025-53652) in the Jenkins Git Parameter plugin.…

### Summary An authentication bypass vulnerability allows any unauthenticated attacker to impersonate any ActivityPub actor by sending forged activities signed with their own keys. Activities are processed before verifying the signing key belongs to the claimed actor, enabling complete actor impersonation across all Fedify instances ### Details The vulnerability exists in handleInboxInternal function in fedify/federation/handler.ts. The critical flaw is in the order of operations: 1. Line 1712: routeActivity() is called first, which processes the activity (either immediately or by adding to queue) 2. Line 1730: Authentication check (doesActorOwnKey) happens AFTER processing ```ts // fedify/federation/handler.ts:1712-1750 const routeResult = await routeActivity({ // ← Activity processed here context: ctx, json, activity, recipient, inboxListeners, inboxContextFactory, inboxErrorHandler, kv, kvPrefixes, queue, span, tracerProvi...
