Threat actors have begun to exploit a chain of vulnerabilities in Plex Media Server to deploy cryptocurrency miners and reverse proxy software, a day after a proof-of-concept (PoC) went public. According to a researcher who goes by the online alias boredhackerblog , the exploitation activity involves chaining four different vulnerabilities, collectively called Plex2Shell . The vulnerabilities are below - CVE-2026-96652 (CVSS score: 5.3) - An unauthenticated server-side request forgery (SSRF) stemming via the "/player/timeline" endpoint by taking advantage of the fact that the "protocol" parameter is inserted into a programmatically-constructed player URL with no validation, allowing an attacker to force the Plex server to POST to a destination of their choice. CVE-2026-96654 (CVSS score: 6.9) - An improper neutralization of URL values included in the "searchOne" endpoint that could allow an attacker to call other plugins' functions and...

Copies of Rank Math PRO, the paid version of the Rank Math SEO plugin for WordPress, that were downloaded from rankmath.com or delivered as updates between 20:02 UTC on October 15 and 07:12 UTC on October 16 contained malware, Rank Math said in a  security notice  published on October 16. Any site that installed and activated one of those copies should be treated as compromised, and the malware can recreate its hidden backdoor whenever someone visits the site. Rank Math has removed the affected files and released a clean version, 3.0.124. Installing it replaces the plugin but does not remove files, administrator accounts, or scheduled tasks the malware may already have placed elsewhere on the server, Wordfence said in an  advisory  on October 17. Who Is Affected The version number does not show whether a copy is affected. Rank Math's  changelog  dates 3.0.123 to October 7, more than a week before the window opened, and the notice limits the inciden...

The worst problems don't always come with a warning. Sometimes they arrive through a service everyone trusts, a device someone bought, or a system nobody thought to check. By the time something looks wrong, the damage may already be done. This week had plenty of that. Trusted connections became a problem. Hardware wasn't as safe as it looked. Old bugs found new victims, and some systems were left so exposed that breaking in barely required any effort. Even AI agents crossed lines they weren't supposed to. Some attacks were clever. Others were painfully simple. The full recap shows just how much can go wrong, and how little it sometimes takes. ⚡ Threat of the Week ConnectWise Suspends Cloud Backup Following Unauthorized Access — ConnectWise disabled seven ConnectWise application identities as it continues its investigation into an incident in which unknown threat actors obtained unauthorized access to the application identities and compromised Microsoft 365 tenant...

In Salesforce Agentforce, the recommended way to make an agent respond to events is a Flow: a record is created or a case is updated, and the Flow passes data into the agent's prompt. Separately, Email-to-Case and Web-to-Case turn inbound customer messages into case records; it is how airlines and hotels run support intake. Both are standard, documented, as-designed features. Chained together, they produce this path: public internet → email → case record → agent prompt → agent action → case comment → outbound reply An unauthenticated outsider now has a route into an internal agent's instructions, and the agent's reply leaves through the same door. Nothing was misconfigured. The finding, documented by researchers in August 2026, is a clean example of how agents that arrive inside existing platforms fail: through the application around them, not the model inside them. The risk is in the application, and the application is the thing nobody re-reviewed Which intake fea...

A flaw in Broadcom's Wi-Fi setup software lets an attacker within radio range run code as root on Broadcom-based routers, without the network password or any pairing step, security researcher Quentin Kaiser  disclosed  on October 16. He showed the attack working against home gateways supplied by three Belgian internet providers, in one case reading the Wi-Fi password off the device and in another opening a remote shell over the air. No CVE has been assigned to the flaw, and no fix has been deployed to the affected routers, Kaiser says. The flaw is in Broadcom's version of Wi-Fi Protected Setup (WPS), the feature that lets a device join a Wi-Fi network without the password being typed in. Broadcom's code mishandles the reassembly of fragmented WPS setup messages, so an attacker in range can send crafted messages that corrupt the router's memory. From there, Kaiser built two things: a way to read memory back off the device, and a way to run his own code on it. Ag...
