The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday urged organizations to take steps to immediately update their Ivanti Connect Secure (ICS) appliances and deployments to the latest version following the disclosure of an actively exploited vulnerability. The security flaw, tracked as CVE-2026-104935 (CVSS score: 8.6), is a case of authentication bypass impacting ICS
The bug was simple: the login let you choose where your sign-in code went. Proving it on a live website was the hard part. TL;DR During an authorized assessment, an AI pentesting agent found a critical authentication bypass on a major insurer's production website, on its own. One login request let the user choose where the one-time passcode went. The attack was the easy part. Proving it
A critical heap buffer overflow vulnerability (CVE-2026-39919) in the Ghostscript interpreter and rendering engine could allow remote code execution through specially crafted PDF files. The flaw was discovered on August 23 by researchers at Defiant's platform Wordfence using their Argus AI-powered system. Ghostscript is a PostScript and PDF interpreter that can render PDFs as images, generate thumbnails for previews, and optimize PDF files by compressing embedded images and removing unnecessary font data. When generating a PDF thumbnail, WordPress can use the PHP Imagick extension to call ImageMagick, which launches Ghostscript. A specially crafted PDF file containing a JPEG 2000 image can trigger incorrect handling of low-bit-depth samples and mismatched component resolutions. Using Argus, the researchers developed two exploits for CVE-2026-39919 that force Ghostscript to write 1,024 bytes into a 256-byte buffer, corrupting nearby memory and leading to unauthenticated remote code execution in a WordPress deployment.
Anthropic is warning that small AI models could soon be able to self-replicate across consumer IoT devices, from Android TV boxes to smart ovens, creating distributed botnets capable of running AI workloads without relying on data centers. The company's experiments showed that models could identify unfamiliar devices, connect them into a network, and prepare them to run an AI model. Although the researchers successfully distributed the Gemma4-26B-A4B model from Google DeepMind on 15 off-brand Android TV boxes, they did not demonstrate a fully autonomous, self-replicating AI worm running on real IoT hardware. However, they estimate that smaller models could achieve self-replication by the end of the year if they continue to improve at their historical rate. “Our experiments suggest that small AI models may be months away from being capable enough to self-replicate on commercial internet-of-things (IoT) devices, like smart ovens and off-brand Android TV boxes,” Anthropic warns.
The U.K. Housing Ombudsman Service is investigating a third-party IT security incident that impacted its case management system on Tuesday. Established under the Housing Act 1996, the Housing Ombudsman is an executive non-departmental public body sponsored by the Ministry of Housing, Communities, and Local Government. The watchdog settles disputes between social housing residents and social landlords in England, including housing associations, landlords, managers, and letting agents. On Tuesday, the service added an alert to its official website, warning that it's working with the affected service provider to assess the incident's impact and said social housing residents cannot file new complaints until systems are back online. Those who must raise new complaints are advised to call the Housing Ombudsman's phone line or email the watchdog at info@housing-ombudsman.org.uk.
U.S. Cybersecurity and Infrastructure Security Agency (CISA) adds Ivanti Connect Secure flaw to its Known Exploited Vulnerabilities catalog. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added an Ivanti Connect Secure FortiMail flaw, tracked as CVE-2026-104935 (CVSS score of 8.6), to its Known Exploited Vulnerabilities (KEV) catalog. The vulnerability is an authentication bypass issue caused by spoofing in ICS versions before 25.1.3.0 that could allow a remote, unauthenticated attacker to execute arbitrary commands. ICS versions 22.7R2.14 and earlier are not affected. “Authentication bypass by spoofing in ICS before version 25.1.3.0 allows a remote unauthenticated attacker to execute arbitrary commands. This does not impact ICS version 22.7R2.14 or prior.” reads the advisory. “Ivanti has released updates for Ivanti Connect Secure (ICS) which addresses one high severity vulnerability. Successful exploitation could allow a remote unauthenticated attacker to execute arbitrary commands.” The company confirmed that the vulnerability was exploited in attacks in the wild. “We are aware of exploitation in the wild affecting a limited number of customers at the time of disclosure.” continues the report. According to Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities, FCEB agencies have to address the identified vulnerabilities by the due date to protect their networks against attacks exploiting the flaws in the catalog. Experts also recommend that private organizations review the Catalog and address the vulnerabilities in their infrastructure. CISA orders federal agencies to fix the flaw by October 16, 2026.

A flaw in SAP's Cloud SDK for Python can send an application's OAuth2 client credentials to a server an attacker controls, SAP said in a security advisory on October 13. The flaw affects multi-tenant applications on SAP Business Technology Platform (BTP) that use the SDK, SAP's official Python client for BTP services. An attacker must be able to control the tenant subdomain,
TFG London detected a cybersecurity incident that impacted IT systems used by the Phase Eight, Hobbs, and Whistles premium fashion brands. The company disclosed earlier today that several IT systems remain unavailable, although physical stores remain open for customers. According to the press release, the incident has not affected the group’s other brands, Inside Story and White Stuff, or its operations in Australia and Africa. TFG London is the UK subsidiary of South Africa’s The Foschini Group, which owns the aforementioned five fashion and homeware brands. As of mid-2026, the group operated 649 retail locations globally and reported annual sales of £488 million ($646M). The company said it detected the cyberattack on October 11 and immediately activated its incident response and business continuity plans, bringing in external cybersecurity experts to help contain the threat.
Attackers continue exploiting gaps in MFA coverage, using stolen credentials to access VPNs, RDP, and Windows systems that still rely on passwords alone. Specops explains why protecting cloud applications isn't enough and how organizations can close these authentication gaps.
SAP has addressed 20 security flaws across multiple products in its October 2026 security updates, including a maximum-severity vulnerability in the Cloud SDK for Python. The SAP Python SDK is the official programmatic toolkit for developing AI agents and Python applications on the company's SAP Business Technology Platform (BTP) services. Tracked as CVE-2026-89111, the maximum-severity vulnerability patched this month can be exploited by remote attackers without privileges to steal credentials. Customers who can't immediately deploy the October 2026 SAP patches can temporarily mitigate the issue by using an allowlist to validate tenant_subdomain values. "The SAP Cloud SDK for Python contains an OAuth2 SSRF vulnerability affecting multi-tenant BTP applications. An attacker who controls the tenant_subdomain parameter can redirect OAuth2 token requests to an attacker-controlled server, causing client credentials to be exfiltrated," according to a Tuesday advisory.
