A OnePlus 15 running the latest OxygenOS can be rooted by a malicious app the owner installs, one that asks for no special permissions. A researcher, Rasmus Moorats,  chained two flaws in OnePlus's own software  to gain root access, the highest level of control over an Android phone. OnePlus told him the same flaws affect many more of its own devices and those of OPPO, though it has not said which. OnePlus confirmed both flaws in May. In the same reply, the company told Moorats that it alone decides when to make a flaw public and warned that publishing without its permission could result in legal liability. He published on September 24 anyway, when OnePlus had released no fix. OnePlus set out its position in the reply,  which Moorats published in full . It said a fix was scheduled, but claimed "the exclusive final right of vulnerability disclosure," and told him that even after a fix ships, researchers may not publish full technical details on their own. The comp...

This week, the dangerous stuff keeps arriving dressed as something boring. An update. A login box. A search answer. A coding tool. A link you have clicked a hundred times before. That is the thread running through the pile. Trusted paths get poisoned. Old bugs find new jobs. AI tools leak more than expected. Fake prompts look real enough. And some attacks barely need an exploit at all — just one weak setting or one person doing what the screen tells them. Nothing here looks especially dramatic. That is what makes it useful. The threats change every week. Subscribe, and we’ll alert you when each new ThreatsDay Bulletin is out.

Threat actors have begun to actively exploit a critical security flaw in WordPress within hours of public disclosure. The vulnerability in question is CVE-2026-87902 (CVSS score: 9.2), which could allow an unauthenticated attacker to obtain remote code execution (RCE). "An unauthenticated attacker can make get_page_template() page-template resolution include a chosen readable local .php file outside the active theme directories," WordPress said in an advisory released two days ago. "If relevant preconditions for both the server environment and the active theme are met, this can lead to RCE." Successful exploitation hinges on meeting the two pre-requisites - The active child or parent theme contains a top-level directory whose name starts with page- (e.g., page-templates). A chosen local .php target file exists on the server and is readable by the web server account. (e.g., pearcmd.php). In a statement shared with The Hacker News, Previdian said it...

Two MikroTik RouterOS SSH vulnerabilities chained together let attackers take full administrative control of Internet-exposed routers without a password, SSH key, or completed authentication. The chain, which CERT Polska calls MikroTrick , combines an SSH state-machine flaw ( CVE-2026-67279 ) with an argument-injection bug in the RouterOS login process ( CVE-2026-86060 ). Attack logs date to at least September 2, one day before MikroTik shipped patches in RouterOS 6.49.21, 7.23.4, and 7.24.2. As  previously reported , CERT Polska warned on September 5 that attackers were using RouterOS flaws to take control of devices whose SSH service was reachable from public networks. That warning confirmed the exploitation and urged immediate patching but did not identify which two flaws formed the chain or explain how they combined. This latest analysis provides both. How the Chain Works SSH requires three steps in order: it establishes an encrypted connection, authentica...

A flaw in cPanel's  CalDAV and CardDAV service  lets anyone with a cPanel hosting account run code as root and take "full control of the server," the company said on September 22. A  second bug in the WP Toolkit plugin, used to install and manage WordPress sites, allows an account holder to change databases that belong to other accounts. cPanel has released fixed versions for both, along with a fix for a  third flaw  in the same service, which stores each account's calendars and contacts. That third flaw lets a local user on the server read other accounts' calendar events and contacts, but not change them or gain root access. cPanel lists no requirements for the root flaw other than having an account. On a shared server where a hosting provider sells accounts to the public, that means any customer could use it. So could anyone who gets hold of a customer's login. The three flaws and the versions that fix them:
