This2Shell, That2Shell, Everything2Shell. That's pretty much how the last week went. Critical bugs that let attackers run code remotely are showing up everywhere. Hackers are scanning for targets, some flaws are already being used in attacks, and security teams have more urgent patches than they can keep up with. And that's not even the full story. A leaked key led to a software supply-chain attack. AI agents are being tricked into following harmful instructions. Old bugs are still being used to break into systems, and some attacks are so simple it's hard to believe they still work. Some websites even went offline to avoid taking chances. It's been a rough week for anyone trying to keep systems safe. Here's what happened. ⚡ Threat of the Week PHP2Shell Flaws Puts Organizations on Alert — The PHP Foundation released patches for two critical vulnerabilities in PHP, CVE-2026-109618 and CVE-2026-109619, that could lead to unauthenticated remote code execution...

PHP has warned of another way an attacker could run code on a web server, two days after it shipped emergency fixes for the critical PHP2Shell flaws. The new issue, assigned CVE-2026-115560 , affects only web applications configured in an unusual way, and PHP considers it an unlikely risk. The project is not issuing an emergency fix for it. Instead, it recommends turning off a feature called session upload progress until a fix is available in the next routine release. The warning came in a short  informational advisory  published on October 23. It follows the October 21  emergency release  that fixed two critical PHP2Shell flaws, CVE-2026-109618 and CVE-2026-109619 , which let an attacker without an account run code on a server. Those were patched in PHP 8.5.12, 8.4.27, 8.3.36, and 8.2.35. The new issue is separate and is not fixed by those releases. Only a narrow setup is at risk. PHP says the problem can occur when a web application does all of the followi...

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 code is secure. The risk is highest on servers using Apache's mod_php, where a working exploit triggers the attack before any application code runs. Both flaws are rated 9.2 on the CVSS v4.0 scale and carry the identifiers  CVE-2026-109618  and  CVE-2026-109619 . PHP published them around the scheduled release time of 14:00 UTC on October 21, a day after details leaked ahead of a planned October 22 disclosure. ⚡ WARNING — PHP Warns of Another Unpatched RCE Flaw CVE-2026-115560 Researchers at Wiz, Calif, and OpenAI found and reported the flaws, which affect nearly every ...

In an update, Palo Alto Networks Unit 42 said it's retracting its earlier assessment that the post-compromise activity targeting the European government agency involved the exploitation of the PHP2Shell flaws. "What researchers saw was an attack against a European government agency executed in the context of a vulnerable PHP application," a spokesperson for the company told The Hacker News via email. "This led us to believe that it was exploitation of those vulnerabilities. We are unable to confirm that initial access is associated with the specific PHP2Shell CVEs." The original story follows. Threat actors have been observed using agentic artificial intelligence (AI) platforms for post-exploitation activity following the abuse of the PHP2Shell vulnerabilities tracked as CVE-2026-109618 and CVE-2026-109619. "In one case, the attackers targeted a government entity in Europe and within two hours of the initial exploitation they had successfully acce...

Palo Alto Networks on Wednesday warned that threat actors are exploiting the recently patched PHP2Shell vulnerabilities against publicly-accessible management interfaces. "Active exploitation has been observed targeting the Palo Alto Networks management interface exposed to the internet," the network security company said in an update to its advisory. The vulnerabilities, tracked as CVE-2026-109618 and CVE-2026-109619 (CVSS scores: 9.2), allow attackers to achieve unauthenticated remote code execution on systems running affected versions of PHP. The issues were patched upstream by the PHP Foundation on October 21, 2026, in versions 8.5.12, 8.4.27, 8.3.36, and 8.2.35. The development comes days after Israeli cybersecurity company Dream said it observed a suspected China-nexus threat actor weaponizing the flaws in conjunction with a local privilege escalation bug in the Linux kernel, tracked as Fragnesia (CVE-2026-46300, CVSS score: 7.8), to root 25 servers across t...

Amazon's Threat Intelligence team on Wednesday said it detected an attempt to exploit the newly disclosed PHP2Shell vulnerabilities dating back to October 17, 2026, against its MadPot honeypot service, as the flaws come under broad exploitation in the wild following the release of the patches. "The exploit attempt originated from an IP address associated with a commercial anonymization network," CJ Moses, CISO of Amazon Integrated Security, said in a post shared with The Hacker News. "While the vulnerability was under embargo, the targeting of a honeypot from an anonymized IP address suggests the activity was conducted by a threat actor, though it remains unclear how the actor acquired exploit information prior to disclosure." The attempt, Amazon said, was recorded from " 103.216.220[.]92 ," an IP address geolocated to Australia. An Amazon spokesperson told The Hacker News the activity was largely a one-off probe, adding "there was no ev...

Threat actors have been observed unsuccessfully attempting to exploit the newly disclosed PHP2Shell vulnerabilities to rope infected systems into a Mirai botnet variant called Potassium , as it emerges that weaponizing the flaws may be harder than previously thought. The attacks aim to exploit CVE-2026-109618 and CVE-2026-109619 (CVSS scores: 9.2), which can result in unauthenticated remote code execution (RCE) via specially crafted HTTP requests. The vulnerabilities have been patched in PHP versions 8.5.12, 8.4.27, 8.3.36, and 8.2.35. "However, analysis of the sample revealed that it is an updated and significantly expanded version of the Mirai-derived botnet variant identified in early 2026," Sophos said . "The sample displays downloader and network disruption functionality." ⚡ WARNING — PHP Warns of Another Unpatched RCE Flaw CVE-2026-115560 Specifically, it resolves a hard-coded, encrypted command-and-control (C2) address, establishes a TCP connec...

Cybersecurity researchers have disclosed details of what appears to be an artificial intelligence (AI)-assisted attack orchestrated by a suspected China-nexus threat actor that has leveraged the PHP2Shell vulnerabilities to breach exposed systems. The activity, which was observed on October 25, 2026, involved an attacker combining PHP2Shell with a kernel privilege escalation exploit to root 25 servers, including three systems in a U.S. government-affiliated environment. "The affected devices run specific versions of a large vendor's firewall software," cybersecurity firm Dream said . "The attacker then launched attacks against Active Directory. The recovered artifacts confirm credential extraction and directory enumeration." The name of the affected vendor was not disclosed, but the Israeli company said it notified the entity. The attack chain essentially brings together two sets of vulnerabilities impacting PHP and the Linux kernel - PHP2Shell , ...

An unknown threat actor has infected 953 online stores, most of them running Magento, as part of a long-running campaign active since July 2025. According to Dutch e-commerce security company Sansec, the activity is designed to add a small piece of code to the store's pages that, when visited by unsuspecting users, serves malicious JavaScript loader code through Magento CMS blocks. "When you visit, that code makes your browser ask the group's server what to do next," Sansec said . "The server first checks whether you are a real shopper or a security scanner, so scanners get nothing." No less than five distinct domains have been observed over time in connection with the campaign - manulfie[.]click, first seen in July 2025 neswnsssn[.]click, first seen in December 2025 lanhd6549tdhse[.]top, first seen in March 2026 additionalver[.]com, first seen in June 2026 deepveindrilling[.]com, first seen in October 2026 Sansec said it found deep...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday confirmed active exploitation of the recently patched PHP2Shell flaws by adding them to its Known Exploited Vulnerabilities ( KEV ) catalog. The PHP vulnerabilities, both rated 9.2 on the CVSS scoring system, facilitate unauthenticated remote code execution on affected deployments - CVE-2026-109618 - An out-of-memory corruption vulnerability that allows for unauthenticated remote code execution. CVE-2026-109619 - A stale internal request-state vulnerability that allows for unauthenticated remote code execution. The addition of the two flaws to the KEV catalog comes after Adel Karimi, detection and response lead at Perplexity, confirmed successful instances of remote code execution against honeypot systems on October 24, 2026. "This is now confirmed RCE with usable memory disclosure, not just a crash followed by a suspicious process," Karimi said . "The response delivered an 800 ...

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. ⚡ WARNING — PHP Warns of Another Unpatched RCE Flaw CVE-2026-115560 Security researchers at watchTowr say the two flaws allow remote code execution. Only the four supported PHP branches, 8.2 through 8.5, can receive the fix, and no exploitation has been reported so far. The  advance notice  followed a leak. On October 20, a  post on HN  said two PHP remote code execution flaws, rated CVSS 10.0 and affecting versions from PHP 5 onward, would be disclosed on Thursday, October 22. The poster said they had "no evidence beyond 'source: trust me, bro'". watchTowr then pos...

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. TeamUpdraft is the developer behind UpdraftPlus, a popular WordPress backup plugin with over four million active installations. The vendor also offers UpdraftCentral, a remote management service that's used for managing multiple sites remotely. A client component of UpdraftCentral is shipped within every copy of UpdraftPlus.  "Over the weekend of 17-18 October we identified unauthorized access to the teamupdraft.com website," TeamUpdraft said in a statement. "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." As a result of the incident, threat actors are believed to have accessed its ...

Some attacks take real skill. Others just need someone to leave a door open. This week has both. Exposed passwords, old bugs still getting exploited, and trusted software doing things it shouldn't. There's a strange mix of clever tricks and careless mistakes. Hackers are borrowing trust from familiar apps, websites, and AI tools. Some are using AI to speed things up. Others are leaving their own attack files exposed. Not exactly careful work. Different stories, familiar weak spots. Here's what showed up this week. The threats change every week. Subscribe, and we’ll alert you when each new ThreatsDay Bulletin is out.

Drupal has warned that threat actors are exploiting a "highly critical" security flaw in its Commerce Core component. The vulnerability, tracked as CVE-2026-118539 (CVSS score: N/A), is a case of missing authorization affecting Commerce Core versions from 0.0.0 to 2.41 and from 3.0.0 to 3.3.13. "This module enables you to sell goods and services to customers through an included shopping cart and checkout form or through decoupled applications via APIs," Drupal said in an advisory. "The module doesn't sufficiently protect certain routes and entity fields, leading to an access bypass that may financially impact the vendor." The open-source content-management framework acknowledged that the vulnerability is being "actively exploited in the wild," but provided no specifics about the nature of the activity or the extent of the campaign. Users are being recommended to update to the latest version - Version 3.x - Upgrade to Commerc...
