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:

Attackers are exploiting a critical flaw in F5 BIG-IP Access Policy Manager (APM) that lets them run code on a BIG-IP system without logging in, F5 says. The flaw,  CVE-2026-94127 , affects only systems in which APM serves as an OAuth authorization server, issuing access tokens to applications. F5 disclosed it in  an advisory  on September 22 and has released engineering hotfixes. APM is the BIG-IP module that controls how users reach an organization's applications and networks. The vulnerable setup has an APM access policy and an OAuth authorization server profile on the same virtual server, which hosts the BIG-IP address that receives the OAuth traffic. Specific malicious traffic sent to that virtual server can lead to remote code execution. The flaw is a heap-based buffer overflow. F5 rates it 9.8 out of 10 on CVSS v3.1 and 9.3 on CVSS v4.0. Because the malicious traffic goes to the virtual server itself, limiting access to the BIG-IP management interface does...

A Chinese threat actor codenamed UTA0565 has been observed exploiting the recently disclosed Google Chrome-Microsoft Windows exploit chain as zero-days through fake websites. The attacks, detected on September 3 and 4, 2026, involved the chaining of two vulnerabilities in Chrome (CVE-2026-85046, CVE-2026-87491) and one impacting Windows Advanced Local Procedure Call (CVE-2026-85880) to break out of the browser's sandbox and achieve remote code execution. "UTA0565 masqueraded as various entities including media organizations and a non-governmental organization (NGO)," Volexity researchers Damien Cash and Tom Lancaster said in an analysis published this week. "Notably, this threat actor's campaigns differed from previously documented attacks by using multiple fake websites to deceive victims." One such campaign targeted Asian government entities with Chinese- and English-language phishing emails that urged recipients to support Hong Kong activist Cho...

A new security vulnerability in Next.js could allow attackers to run code on a server via  ImageResponse , the feature that generates Open Graph and other social preview images, Vercel said. The risk applies when an app puts values an attacker controls, such as text read from the request URL, into the image. Vercel, which develops Next.js,  fixed the flaw  on September 22 in version 16.3.6. The flaw, tracked as CVE-2026-94545 , affects Next.js 16.2.0 through 16.3.5 when ImageResponse runs on the Node.js runtime, which Next.js  uses by default . Vercel's  advisory  rates it critical, with a CVSS score of 9.5. The Edge version of ImageResponse is not affected, and neither is Next.js 15. ImageResponse uses  Satori , a Vercel library, to convert the image layout into SVG code before the final PNG is generated. Affected apps are those that "pass attacker-controlled values into SVG content, attributes, or styles during image generation", according to ...

The cyber extortion group known as ShinyHunters on Tuesday claimed it had breached the U.S. Federal Bureau of Investigation and stolen data belonging to current and former employees at the agency. "We have compromised the FBI. We hold very sensitive data on almost ALL FBI Agents and individuals who filed an application with the FBI for a job," the group said in a statement posted on their dark web site. "Whether it be a Special Agent or any other role within your agency. The following FBI services were compromised: Criminal Justice (CJ), HR, Medlink, and more." The development was first reported by 404 Media. ShinyHunters said the FBI was targeted in response to a May 2026 public service announcement (PSA) that detailed the threat actor's targeting of Canvas , an online Learning Management System (LMS), while urging victims not to pay. The attackers, in their own counter PSA, described them as "substantial false allegations," adding, "w...

Attackers exploited a previously unknown flaw in Check Point's Security Management Server in a handful of targeted attacks on July 23,  the company said . The flaw, CVE-2026-93616 , allows an attacker who can access the server's web service to run scripts on it without logging in. Check Point released a fix on September 22 for the server that controls firewall policies for the Check Point gateways it manages. Separately,  Check Point said  attackers have been trying since September 12 to exploit a VPN flaw it  fixed on September 9 . The attempts, against a flaw tracked as CVE-2026-85102, have targeted customers of Spark, Check Point's firewall line for small businesses. When the fix came out, Check Point had no evidence the flaw was being exploited. CVE-2026-93616 is a path traversal bug in the management server's web service. The service does not properly limit which files and folders a request can reach. An attacker can use it to upload scripts to the s...

WordPress has fixed a critical flaw in its core software that lets an attacker with no account make a site load a PHP file from outside its theme folders. On some servers, that can go further, allowing the attacker to run their own code. The fix shipped on September 22 in WordPress 7.1.2, with fixes for every branch the project still supports, back to 4.7, and WordPress is telling site owners to  update now . WordPress rates the flaw as critical, assigns it a CVSS score of 9.2, and assigns it  CVE-2026-87902 . Reaching it requires no account and no action from a logged-in user. Every version from 4.7.0 through 7.1.1 is affected. That includes 7.1.1, from WordPress's  September 17 security release , so a site updated less than a week ago still needs this one. It is a separate flaw from the ones that the release fixed.

A critical vulnerability in  Bifrost , an open-source AI gateway that routes requests to more than 20 LLM providers, allows an unauthenticated attacker to run arbitrary commands on the gateway server with a single HTTP request. The flaw, tracked as  CVE-2026-90898  (CVSS score: 9.8), affects all versions of the Bifrost HTTP transport before 2.1.0 when management authentication is disabled, which is the default configuration. A fix is available in transports/v2.1.0. Yuval Moravchick of  JFrog Security Research , who discovered the flaw, said an attacker can register a stdio-type MCP client through a single unauthenticated POST to the management API endpoint /api/mcp/client. Bifrost starts the specified command immediately, before any MCP handshake, as the gateway process user. On the official Docker image, that user is appuser. Because the gateway stores API keys for every connected provider, executing commands on the gateway process grants the attack...

A SharePoint Server vulnerability that Microsoft initially classified as a spoofing flaw with a CVSS score of 6.5 actually enables authenticated remote code execution, according to full technical details published today by Viettel Cyber Security researcher Dinh Ho Anh Khoa. The flaw, CVE-2026-65660 , affects SharePoint Server 2016, 2019, and Subscription Edition. Patches have been available since the  August 11 security updates , and the National Vulnerability Database scores it 8.8. Microsoft's advisory  describes CVE-2026-65660 as allowing an authorized attacker to perform spoofing and assigns no impact to integrity or availability. The CVE record that Microsoft publishes separately, updated on September 11, titles the same flaw a remote code execution vulnerability and says it allows an authorized attacker to execute code. Both records assign CWE-94, a code-injection weakness. Defenders who triaged CVE-2026-65660 based on the advisory saw a moderate spoofi...

A new flaw in WordPress core let an anonymous visitor leave a comment that planted a hidden script on the page. If a logged-in administrator later opened that page, the script could run code on the site's server. WordPress fixed the flaw, tracked as  CVE-2026-93485  and called " Comment2Shell ," on September 17 in  version 7.1.1  and told site owners to update right away. There is no sign it has been used in attacks, and it is not on the U.S. government's list of actively exploited software flaws. Patchstack, the company that assigned that identifier, rated the flaw 7.1 out of 10 on the CVSS scale. WordPress checks a comment for dangerous HTML when it is saved, then reformats it when the page is shown, and the flaw sat in the gap between those two steps. Rafie Muhammad, the security researcher who reported the bug, laid out the full chain in  a write-up  on September 21. The trick was a line break placed inside the attribute of an allowed HTML tag ...

Three researchers at the security firm  Hacktron  used Anthropic's Claude Opus 5 to chain two flaws and take over the ChatGPT and Codex accounts of several OpenAI employees, then reach an internal OpenAI code repository. The chain began with a bug in the software that runs OpenAI's public help forum and moved through a weakness in OpenAI's own login system. This was security research, not a real-world attack: the team reported the flaws to OpenAI, proved the access with a harmless pull request, and then stopped. From the first look, that internal access took under 72 hours. OpenAI confirmed a fix about 14 hours after the report, according to Hacktron, and on September 1 paid the team a $6,500 bounty. OpenAI said the award "recognizes the OpenAI-side finding, not the actions against Discourse," the open-source software that runs the forum. Testing the forum itself was outside its bug bounty program. OpenAI has not publicly described the login flaw, and it ...

A critical vulnerability impacting Orkes Conductor is being actively exploited in the wild, according to Fortinet. The vulnerability in question is CVE-2026-58138 (CVSS v3.1 score: 9.8/CVSS v4 score: 9.3), which relates to a case of unauthenticated remote code execution. "Orkes Conductor 3.21.21 before 3.30.2 contains an unauthenticated remote code execution vulnerability that allows remote attackers to execute arbitrary OS commands by submitting inline workflow definitions containing malicious JavaScript or Python expressions to the workflow API endpoint prior to authentication," a description of the flaw on the NIST National Vulnerability Database (NVD) reads. "Attackers can exploit unsandboxed GraalVM evaluators configured with HostAccess.ALL or allowAllAccess(true) through INLINE, LAMBDA, DO_WHILE, and SWITCH task types to invoke arbitrary system commands via Java reflection or direct subprocess calls." In an outbreak alert issued this week, Fortinet ...

Google's Gemini model has become the latest artificial intelligence (AI) system to access the internet and break into other companies during a cybersecurity evaluation. The development was first reported by The Wall Street Journal. The incidents occurred in May 2026 as part of a test run conducted by Israeli company Irregular. The evaluation partner was also involved in similar hacks disclosed by OpenAI, Anthropic, and Meta. According to the Journal, the model gained access to a protected system after repeatedly guessing its password. Two other cases related to the model finding credentials in a public repository, allowing it to obtain unauthorized access to protected systems. However, unlike other incidents observed in the case of Anthropic and OpenAI, the Gemini model ended the intrusion after finding that it had breached a real company's system. Irregular is said to have notified Google of the incidents in July 2026. In a report published last month, Irregular pinn...

WordPress today released patches to fix a new set of vulnerabilities in its core software, one of which could allow a crafted web link, opened by a logged-in administrator, to install a theme from the official WordPress.org directory without anyone clicking Install. The security firm pwn.ai , whose researchers reported the flaw, calls the attack chain Click2Shell . On its own the flaw only installs a real theme that the attacker picks, but the security research team showed it could be combined with a separate weakness in a theme to run the attacker's own code on the server.  The fix shipped on September 17 in WordPress 7.1.1 . Because this is a security release, WordPress advises updating right away. There is no sign the flaw has been used in real attacks. The installed theme stays switched off, so the site's own appearance does not change and nothing looks wrong. Reaching code execution needed a second, separate flaw in the theme that was installed. As pwn.ai wrote of t...

In July 2025, someone registered a domain that used to belong to a content delivery network.  The CDN had been wound down years earlier, and the domain it served assets from was allowed to expire. What it had not lost were its callers. Thousands of websites, code repositories, and documentation pages still carry hard-coded references to hostnames beneath it.  The new owner holds wildcard DNS across the entire domain, and any hostname under it now resolves to infrastructure that person controls. Today the apex serves an ad-heavy media downloader page, which is unremarkable. The remarkable part is that the decision about what those thousands of pages load next belongs to a stranger, and nobody involved has been notified, because from the outside nothing broke.  This pattern is not hypothetical, and it's not unheard of either. In June 2024, the polyfill.io domain (a JavaScript shim embedded in more than 110,000 sites) changed ownership and began serving conditional redi...

Cybersecurity researchers have discovered a cluster of 13 npm packages that have been found to deliver a previously undocumented JavaScript stealer codenamed WeaselBiscuit . The new malware family, per OpenSourceMalware , exhibits functional overlaps with two malware strains associated with the Democratic People's Republic of Korea's (DPRK) Contagious Interview campaign: BeaverTail and OtterCookie . "It's smaller, lighter, and stripped down, with many of the heavier functions removed entirely," security researcher Paul McCarty (aka 6mile) said. The names of the packages are below - @biz44/id10-client @biz44/id12-client @biz44/id44-client @biz44/id79-client @biz44/id95-client @biz44/id99-client @biz44/process-runtime-utils @biz44/runtime-utils engin1 id79-client process-lhpm process-mite process-tailwind "It's a stripped down stealer that borrows several functions from DPRK's BeaverTail and OtterCookie,...

Attackers now weaponize new vulnerabilities in about five days (Mandiant, part of Google Cloud). The median organization takes 43 days to patch one (Verizon DBIR 2026). A new free guide explains how autonomous AI agents are closing that gap, and what security leaders must demand before pointing one at production. TL;DR Exploitation is now the front door. It starts 31% of breaches (Verizon DBIR 2026), the #1 initial-access vector, while annual pentesting leaves an estimated 90% of the estate untested. The capability is proven, not projected. An autonomous system topped HackerOne's US leaderboard in 2025 (XBOW), and peer-reviewed agents exploited 87% of one-day flaws unaided (Fang et al., 2024). Continuous beats periodic, measurably. Programmatic testing makes teams 4.5x more likely to fix criticals within three days (Cobalt, 2026). It's an AI agent in your production. Hold it to a bar. Provable coverage, an independent validator, blast-radius guardrails, and a...

A security breach at Gyazo , Helpfeel's image-sharing service, exposed about 23.62 million user records, including email addresses and password hashes, the Kyoto-based company said in a  notice  published Wednesday. It also exposed about 490 million image metadata records, mostly for images from January 2019 or earlier, including the IDs that make up Gyazo image links. Helpfeel said those IDs could be used to view the images without permission, and that it has temporarily disabled viewing of some of them. Helpfeel asked every Gyazo user to change their password and to change it on any other service that uses the same or a similar one. It also asked users to watch for suspicious emails or messages related to the incident. The attacker gained access through a vulnerability in Gyazo's image upload server, ran arbitrary commands on Helpfeel's systems, and accessed Gyazo's database, the company said. It has not said what kind of flaw it was. Helpfeel said no pay...

Cisco has warned of a fresh maximum-severity security flaw impacting Identity Services Engine (ISE) that has come under active exploitation. The vulnerability, tracked as CVE-2026-76460 (CVSS score: 10.0), could allow an unauthenticated, remote attacker to bypass authentication. "This vulnerability is due to insufficient authentication control on an API endpoint," Cisco said. "An attacker could exploit this vulnerability by sending a crafted request to an affected API endpoint. A successful exploit could allow the attacker to gain unauthorized access to the affected device by bypassing the web-based management interface." The issue affects Cisco ISE and Cisco ISE Passive Identity Connector (ISE-PIC), regardless of device configuration. It has been addressed in the following versions -

A critical security flaw in Issabel Framework , a web-based framework for the open-source unified communications PBX software, has come under active exploitation. The vulnerability in question is CVE-2026-89026 (CVSS v3.1 score: 9.8/CVSS v4.0 score: 9.3), which can allow an unauthenticated remote attacker to execute arbitrary operating system (OS) commands by taking advantage of a hard-coded JSON Web Token (JWT) signing key. The Issabel Framework "contains a hard-coded HS256 JWT signing key in the pbxapi index.php file that is identical across every installation, allowing unauthenticated remote attackers to forge valid bearer tokens," VulnCheck said in an alert. "Attackers can use the forged token to call the manager '/pbxapi/manager/originate' endpoint with the System application parameter, causing Asterisk to execute arbitrary OS commands as the Asterisk user." A patch for the vulnerability was pushed on August 1, 2026, and plugs the flaw by r...
