The PHP security team released emergency security patches for two critical remote code execution (RCE) vulnerabilities (CVE-2026-109618 and CVE-2026-109619) tracked collectively as PHP2Shell. The two unauthenticated RCE flaws were discovered by Calif, Wiz, and OpenAI security researchers, and affect all PHP installations that serve web requests, including PHP-FPM, Apache with mod_php, php-cgi, FrankenPHP, and LiteSpeed. "We consider the risk highest for mod_php, with a demonstrated exploit where an unauthenticated request can trigger the attack before any application code runs," the PHP security team said. Both flaws stem from the same underlying problem: PHP can leave its memory in a corrupted state when a request ends abnormally, and both can be exploited to achieve remote code execution. CVE-2026-109618 can be used to gain remote code execution as the web worker account by exploiting a chain of weaknesses that trigger out-of-memory corruption, while the CVE-2026-109619 stale global state vulnerability enables unauthenticated heap use-after-free, memory disclosure, and remote code execution with the web worker's privileges.
PHP has released emergency updates that fix two critical flaws in the language itself, letting an attacker without an account run code on a web server. The fixes are in PHP 8.5.12, 8.4.27, 8.3.36 and 8.2.35, and the PHP team says only updating fully protects a server. The flaws, together called PHP2Shell, sit in the PHP runtime, not in any application, so a site is exposed even when its own
CVE-2026-109618 and CVE-2026-109619 are Critical vulnerabilities in PHP, a scripting language used globally for web servers and CMS systems. The post Threat Brief: Critical Vulnerabilities in PHP: CVE-2026-109618, CVE-2026-109619 appeared first on Unit 42.
Google on Tuesday said it's rolling out improved safeguards in its Chrome browser to secure users against ClickFix attacks when Enhanced Protection is enabled. ClickFix is a popular social engineering technique in which bad actors trick users into copying and pasting malicious code directly into their computer's operating system, thereby bypassing conventional security controls.

PHP prepares emergency patches for two critical RCE flaws, while older, unsupported versions could remain exposed without vendor fixes. The U.S. government ordered federal civilian agencies to remove DeepSeek products from their IT systems and stop buying them. The order also reaches third-party tools and services built with DeepSeek implementations, which is the part most organizations should notice. The notice doesn’t explain exactly what counts as a “DeepSeek implementation.” Agencies will need to ask suppliers whether their products fall under the ban. “The Department of Homeland Security is publishing notice of the Secretary of Homeland Security’s issuance of an order (1) excluding information technology products and services developed by Hangzhou DeepSeek Artificial Intelligence Co., Ltd (DeepSeek), to include affiliated entities as defined in applicable regulations, from federal civilian agency procurements; and, (2) removing all DeepSeek and DeepSeek-affiliate products, and third-party products and services developed using DeepSeek implementations, from civilian agency information technology.” reads the order. Homeland Security Secretary Markwayne Mullin signed the order on July 24, 2026, under the Federal Acquisition Supply Chain Security Act of 2018. DHS published it in the Federal Register on October 20 as document 2026-21447, under docket DHS-2026-0628. The order cites national-security concerns. According to reporting on the notice, DHS said DeepSeek’s models could transfer sensitive data to China and may contain malware or other security weaknesses. “In a notice made public on Monday, the Department of Homeland Security also barred agencies from acquiring DeepSeek products and services, including those developed by affiliated entities.” South China Morning Post reports, “The notice said that using the company’s products “may result in the transfer of sensitive data to the PRC if used by US government employees or vendors”, adding that the models “themselves may contain malware or other security vulnerabilities”.” DeepSeek’s own privacy policy says it collects, processes, and stores personal data in the People’s Republic of China. That does not prove wrongdoing, but it explains why U.S. agencies treat data residency and foreign legal access as material risks. The ban doesn’t apply to private companies or ordinary users, but government contractors may also be affected. They generally can’t use covered products or services for federal contracts unless they receive a waiver. The goal is to catch hidden uses of DeepSeek, including AI models built into apps, services and development tools. Agencies need to check their systems, while suppliers must disclose which AI models they use, where the models process data and whether information leaves the customer’s environment. The ban took effect when issued, but existing contracts are covered only after the contracting officer formally updates them. Agencies can request an exception, but they must provide a strong justification. DHS signed the order on July 24 but didn’t publish it until October 20, 87 days later. The rules don’t set a deadline for public release, but they require officials to notify the company and relevant congressional committees and review the order at least once a year. This delay meant affected organizations had to comply before they could read the public explanation or see the signed order. China pushed back. Foreign Ministry spokesperson Mao Ning said Beijing opposes “the overstretching of the concept of national security” and would defend the lawful rights of Chinese companies; DeepSeek did not immediately comment to the Associated Press.[apnews] Follow me on Twitter: @securityaffairs and Facebook and Mastodon Pierluigi Paganini (SecurityAffairs – hacking, AI)
You cannot fully block the two critical PHP flaws called PHP2Shell before today's fix, and the one setting being passed around as a workaround is not enough on its own, the security firm that suggested it now says. PHP will release the fix at 14:00 UTC on October 21 for two flaws it rates 9.2 out of 10, and has given no workaround of its own. Until you can install it, what lowers your
This story is developing and was written before PHP's scheduled 14:00 UTC release on October 21. Once the release is out, the affected and fixed versions below are confirmed by the official advisory. PHP will ship an out-of-cycle security release at 14:00 UTC today, October 21, for two critical vulnerabilities that its security team has rated 9.2 on the CVSS v4.0 scale but has not described.
Unknown threat actors breached TeamUpdraft's website and potentially gained unauthorized access to customers' connection keys for UpdraftCentral, UpdraftVault, and UpdraftClone, using them to backdoor WordPress sites.

State Bank of India has identified 3,897 customer records containing personal information in a set of about 375,000 records available on the dark web, and it does not yet know where the data came from. The state-owned bank, India's largest, said in a stock-exchange filing dated October 21 that it "has experienced an incident involving the loss of certain data." The count is
A threat actor breached TeamUpdraft's website, a developer of popular WordPress backup and security plugins, potentially compromising UpdraftCentral connection keys that can send commands to connected websites. TeamUpdraft detected unauthorized access to its infrastructure over the weekend and believes that the hacker accessed the customer database. The developer offers several WordPress tools for backup, storage, and site management: "Over the weekend of 17-18 October we identified unauthorised access to the teamupdraft.com website," TeamUpdraft said in an advisory yesterday. "Our team responded straight away and worked through the night to contain it – we closed the access route, signed out every account and replaced the keys and credentials that could have been affected." The vendor says it believes the threat actor accessed its customer database, which included details about the customer and billing, order history, as well as more sensitive information:
