Apple patches CoreGraphics zero-day flaw exploited in attacks

Apple on Monday released iOS and macOS updates to patch a zero-day vulnerability that may have been exploited in targeted attacks. The flaw, tracked as CVE-2026-86950, is an out-of-bounds write issue in the CoreGraphics component that can be exploited for arbitrary code execution when it processes a specially crafted file. Apple has not said how the malicious file is delivered, but because CoreGraphics handles 2D graphics and PDF rendering across the operating system, it could arrive via web pages, email attachments, or messaging apps, where automatic attachment and link previews could enable zero-click exploitation. “Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals on versions of iOS before iOS…

Apple patches CoreGraphics zero-day already exploited in targeted attacks
Apple has patched a CoreGraphics zero-day after warning that attackers may already have used the bug to compromise a small number of carefully chosen targets. The vulnerability, tracked as CVE-2026-86950, is an out-of-bounds write flaw in CoreGraphics, Apple's framework for handling graphics across its operating systems. According to Apple's advisory, processing a maliciously crafted file could allow an attacker to execute arbitrary code on a vulnerable device. The fruity vendor said it addressed the problem with improved bounds checking, though the bug appears to have made it out into the wild before Apple could squash it. "Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals on versions of iOS before iOS 27," the company said. As is customary when Cupertino encounters the sort of security bug somebody has apparently found useful, further details are thin on the ground. Apple didn't say who was targeted, how many people were affected, who was behind the attacks, or exactly how the vulnerability was being exploited. However, its choice of words suggests this wasn't a bug being exploited indiscriminately across the internet, and raises the possibility that it was used as part of a targeted spyware campaign. Meta Product Security reported CVE-2026-86950 to Apple, but neither Apple's advisory nor Meta has provided further technical details on how the flaw was discovered or the attacks in which it was allegedly used. The fix landed on Monday in iOS 26.7.1 and iPadOS 26.7.1. Apple lists affected devices receiving the update as the iPhone 11 and later, iPad Pro 12.9-inch (third generation and later), iPad Pro 11-inch (first generation and later), iPad Air (third generation and later), iPad (eighth generation and later), and iPad mini (fifth generation and later). Apple specifically says the attacks hit devices running versions of iOS before iOS 27, though it hasn't said exactly which older releases were targeted. The flaw adds another entry to Apple's growing collection of vulnerabilities caught being abused before users had a patch, with CVE-2026-86950 landing as the seventh zero-day fixed by the company this year. For anyone still running the affected releases, that leaves the usual less-than-thrilling security advice: install the update rather than waiting to find out exactly what an "extremely sophisticated attack" looks like. ®

Update your iPhone, iPad, or Mac: Flaw could run attackers’ code
Apple has released updates for iPhones, iPads, and Macs to fix a flaw that could let an attacker run code when a device processes a malicious file. Apple says it may have been used in highly targeted attacks against iPhone users running versions of iOS before iOS 27. The fix is in iOS and iPadOS 26.7.1, as well as macOS Sequoia 15.8.1 and macOS Tahoe 26.7.1. Check Software Update on each of your Apple devices and install the latest version offered. Updates for your particular device The table below shows which relevant updates are available and links to Apple’s security information for each one.

Make sure your Mac stays plugged in and connected to the internet until the update is done. Technical details The bug, CVE-2026-86950 , affects CoreGraphics, an Apple framework used throughout its operating systems and apps to display and process visual content such as images and PDFs. It’s an out-of-bounds write issue, which Apple addressed with improved bounds checking. This type of bug happens when software writes data beyond the limits of its allocated area of memory. It can overwrite other data in memory, interfere with the normal operation of the program, cause a crash, or even let an attacker take control of the affected process. In this case, processing a maliciously crafted file may lead to an attacker running their own code. Apple says it is aware of a report that the issue may have been exploited in an “extremely sophisticated attack” against specific people using versions of iOS before iOS 27. Although the reported attack was highly targeted, other attackers could try to exploit the flaw now that it has been disclosed.  Scammers know more about you than you think.   Malwarebytes Mobile Security protects you from phishing, scam texts, malicious sites, and more.

Apple Patches Zero-Day Linked to ‘Extremely Sophisticated Attack’
Apple on Monday released iOS and macOS updates to patch a zero-day vulnerability that may have been exploited in targeted attacks. The flaw, tracked as CVE-2026-86950, is an out-of-bounds write issue in the CoreGraphics component that can be exploited for arbitrary code execution when it processes a specially crafted file. Apple has not said how the malicious file is delivered, but because CoreGraphics handles 2D graphics and PDF rendering across the operating system, it could arrive via web pages, email attachments, or messaging apps, where automatic attachment and link previews could enable zero-click exploitation. “Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals on versions of iOS before iOS 27,” Apple said in its advisory. No information has been shared on the attacks exploiting CVE-2026-86950, but Apple noted that it learned about the vulnerability from Meta’s product security team. Meta’s involvement is noteworthy given a similar incident from last year, when WhatsApp said a vulnerability in its iOS and macOS apps (CVE-2025-55177) was likely used alongside the Apple ImageIO zero-day CVE-2025-43300 in zero-click attacks aimed at fewer than 200 users. It’s unclear whether the newly patched CoreGraphics flaw was exploited through WhatsApp. SecurityWeek has reached out to Meta for clarification and will update this article if the company responds. CVE-2026-86950 has been patched with the release of iOS 26.7.1, iPadOS 26.7.1, macOS Tahoe 26.7.1, and macOS Sequoia 15.8.1. While both iOS and macOS are impacted, Apple’s advisory suggests that attacks have only been observed against the former. The latest iOS 27 and macOS Golden Gate 27 do not appear to be affected. CISA has yet to add CVE-2026-86950 to its KEV catalog. This would be the ninth Apple product flaw added to the catalog this year.

WSO2 and Adobe Commerce Flaws Exploited in Attacks, Added to CISA KEV
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday added two security flaws impacting Microsoft SharePoint and Mikrotik RouterOS to its Known Exploited Vulnerabilities (KEV) catalog, citing evidence of active exploitation. The vulnerabilities in question are as follows - CVE-2026-65660 (CVSS score: 8.8) - A code injection vulnerability in Microsoft Office SharePoint that allows an authorized attacker to execute code over a network. CVE-2026-67279 (CVSS score: 6.9) - An improper enforcement of behavioral workflow vulnerability in Mikrotik RouterOS that could allow an unauthenticated client to open a session channel and send an exec request. As reported by The Hacker News earlier this week, CVE-2026-65660 was originally described by Microsoft as a spoofing vulnerability impacting SharePoint Server. The tech giant has since updated the advisory to state that it could be abused to obtain remote code execution. "As of 9/25/2026, Microsoft had reliable evidence of observed attacks against exploitation of this vulnerability," the Windows maker noted. Microsoft hasn't disclosed who was behind the exploitation efforts, when they started, how many organizations have been targeted, how many of them have been successful, and what attackers did once inside the vulnerable service. The second vulnerability to be added to the KEV catalog is CVE-2026-67279, which has been chained along with CVE-2026-86060, an argument injection flaw in the RouterOS login process, as part of an exploit codenamed MikroTrick. The exploit chain has been employed to take full administrative control of internet-exposed susceptible routers without the need for a password, per CERT Polska. "Combining the two vulnerabilities resulted in full unauthenticated access to the administrative console," the Polish cybersecurity agency said. "CVE-2026-67279 allowed an unauthenticated client to create a session channel, while CVE-2026-86060 allowed it to supply login with an attacker-controlled policy mask." In a separate analysis, Bishop Fox said it was able to reproduce the complete administrative takeover on vulnerable RouterOS 7.x builds. "MikroTrick combines two failures at different trust boundaries," security researcher Emilio Gallegos said. "The first allows an unauthenticated connection to reach functionality that RouterOS should expose only after login. The second causes the login process to treat data from that connection as a trusted administrative identity." "MikroTrick exposes a design risk in privileged software: a feature intended only for trusted local callers becomes a remote attack surface when an upstream component loses track of authentication state." It's worth noting that CISA added CVE-2026-86060 to its KEV catalog on September 11, 2026. Federal Civilian Executive Branch (FCEB) agencies have time until September 28, 2026, to apply the necessary fixes.
