The Canadian Centre for Cyber Security has warned that a now-patched Roundcube Webmail vulnerability is being actively exploited in the wild. The vulnerability in question is CVE-2026-48842 (CVSS score: 8.1), a pre-authentication SQL injection in the virtuser_query plugin of Roundcube Webmail versions 1.6.x before 1.6.16 and 1.7.x before 1.7.1. The issue stems from a preg_replace() backslash escape bypass that allows attackers to inject arbitrary SQL statements without authentication. "Unauthenticated attackers can inject SQL into Roundcube's database backend through the virtuser_query plugin, potentially exposing mail account credentials and stored messages," SentinelOne said . Patches for the vulnerability were released by Roundcube in May 2026 as part of 1.6.16 and 1.7.1. In an update shared this week, the Cyber Centre said the security flaw is being actively exploited in the wild, citing open-source reporting. No additional details of the exploitation ac...

A flaw in Cloudflare Containers let a paying customer read data that other customers' containers had left behind on the same server, Cloudflare and the researchers who found it said on Thursday. The data came from disk space that earlier containers had used and given up, not from any live workload, and an attacker could not choose whose data they got,  according to Cloudflare . The company has fixed the flaw across its service and says customers need to do nothing. Cloudflare Containers runs customers' programs inside containers on servers shared by many accounts, and Cloudflare, not the customer, picks the server. Cloudflare Sandboxes, which runs on Containers and is sold as a safe place to run untrusted code, including code written by AI agents, was affected too. The flaw was reported on September 4 by Oren Yomtov of the security firm Accomplish , through Cloudflare's bug bounty program. The problem was in how the shared disks were set up. Each container gets a ...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA), on Thursday, added two critical security flaws impacting WSO2 and Adobe Commerce and Magento to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active exploitation. The vulnerabilities are listed below - CVE-2026-5430 (CVS score: 9.8) - A path traversal vulnerability in  WSO2 API Control Plane, API Manager, Traffic Manager and Universal Gateway that could allow unrestricted file upload and lead to remote code execution. CVE-2026-71362 (CVSS score: 9.1) - An incorrect authorization vulnerability in  Adobe Commerce and Magento that could allow an attacker to leverage this vulnerability to gain elevated access to sensitive resources without any user interaction. The addition of CVE-2026-5430 to the KEV comes a little over a week after watchTowr said it's seeing in-the-wild exploitation efforts against its honeypots since at least September 13, 2026. "We captured forged JW...

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.
