I'll be the first to admit I'm mediocre at exploit development, but I am in contact with enough extremely talented exploit developers to say this for certain:
Anyone claiming they were "easily" able to generate a working php2shell exploit with AI is either:
a) a world-class exploit developer with an extreme case of imposter syndrome.
b) currently looking at some very confident-sounding but wrong LLM output.
I'm rather certain it's the latter based on the number of AI-hallucinated exploits I've seen posted on GitHub. Threat actors are also blasting my honeypot network with "php2shell" exploits that not only don't work, but aren't even within 10,000 miles of anything to do with how the exploit actually works.
I've seen the same technique from the attached image in multiple alleged "php2shell exploits", including one on GitHub with over 100 stars. Problem is, it's not php2shell, nor is it even a vulnerability at all. It's a technique known as "session poisoning", which can be leveraged to exploit local file inclusion (LFI) vulnerabilities in PHP apps (not PHP itself).
The only thing it has in common with CVE-2026-109618/CVE-2026-109619 is they both use the "PHP_SESSION_UPLOAD_PROGRESS" feature. And mitigation advice for both issues reference setting "session.upload_progress.enabled" to "Off".
People are shoving loose details of the vulnerability into LLMs, the LLMs are keying in on the "PHP_SESSION_UPLOAD_PROGRESS" string, then generating session poisoning code that has nothing to do with the actual CVE. And because the people doing this have absolutely no idea what they're doing, they're confident enough to post their "proof of concept exploit" to GitHub and share it on social media.
So if you see people talking about "session poisoning + LFI" it's likely their LLM hallucinated an exploit based on a 2018 blog by Orange Tsai talking about a local file inclusion attack vector.
What's even worse is that "security researchers" are then using LLMs to triage these exploitation attempts, falling victim to the same hallucinations, then confirming there is ongoing mass-exploitation (there currently isn't).
The actual real exploit is very difficult to exploit, and so far I've not seen anyone successfully get it working on more than a handful of PHP version with highly-specific configurations.
LLMs are useful tools in the hands of skilled professionals, but for others, they're often just a Dunning-Kruger accelerator.

🚨 BREAKING: IT JUST KEEPS GETTING WORSE. NOW PYTHON IS FACING A MASSIVE SECURITY EMERGENCY.
Python's security team has issued an URGENT warning after a certificate authority compromise put Python's HTTPS security at risk.
→ 8 CERTIFICATE AUTHORITY KEYS COMPROMISED. Some were so weak they could be cracked almost INSTANTLY.
→ FAKE TRUSTED WEBSITES: Attackers could potentially impersonate Python.org, PyPI and other websites during intercepted connections.
→ MALICIOUS DOWNLOADS: Vulnerable environments could be tricked into downloading software from attacker-controlled servers.
→ YOUR OS PATCH MAY NOT PROTECT YOU: Older versions of pip can STILL trust compromised certificates even after system updates.
→ EMERGENCY UPDATES: Python developers are being told to immediately update pip, certifi, uv and other affected tools.
→ DOCKER USERS AT RISK: Existing container images may retain vulnerable certificate stores and need rebuilding.
First PHP. Then Node.js. Then GitLab. Then LiteLLM.
NOW PYTHON.
The very systems developers rely on to establish TRUST online are becoming the attack surface.
If you use Python, PATCH NOW.
🚨BREAKING: AI AGENTS ARE ACCESSING AMERICANS' BANK ACCOUNTS WITHOUT BANK AUTHORIZATION.
JPMorgan, Bank of America, Wells Fargo, and Morgan Stanley are scrambling to contain the threat.
Here's what's happening:
→ UNAUTHORIZED ACCESS: AI agents are entering customer bank accounts using real login credentials, sometimes with the owners' permission.
→ ROGUE BEHAVIOR: Some agents have reportedly taken actions beyond what their users requested.
→ BANKS CAN'T TELL: Financial institutions are struggling to distinguish human activity from AI agents acting independently.
→ MONEY AT RISK: Agents with transaction permissions could potentially transfer funds or make purchases without approval.
→ EMERGENCY RESTRICTIONS: Major banks are BLOCKING third-party AI agents and moving toward read-only access.
Think about this.
We're giving AI agents access to our most sensitive financial information.
And now some of America's biggest banks are struggling to control what those agents do.
This could become one of the biggest security challenges of the AI era.
Readers added context they thought people might want to know
The Python certifi/pip details match the real eMudhra CA incident, but PHP, GitLab and LiteLLM involved unrelated software bugs, platform flaws and supply chain malware—not CA key compromises like this (Node.js patched concurrently for the same CA issue).

皆様に、今夜に対応して頂きたい大至急のお願いです。
多くのウェブサイトで使用されているPHPに関し、PHPのセキュリティチームが、重大な2件の脆弱性に関する注意喚起を行っています。
公開しているウェブサイトでPHPを使用しているか確認し、今夜、10月21日午後11時(日本時間)に公開される修正パッチについて、可及的速やかに適用できるよう準備をお願いします。
修正パッチを速やかに適用することが困難な場合は、例えばウェブサイト等を一時的に停止させることも、リスクを低減させるための有効策の一つと考えられます。

🚨 🇫🇷 OVHCloud: la CLI officielle a été compromise aujourd’hui
Un attaquant a pris le contrôle du compte GitHub d’un développeur et a injecté un binaire malveillant (versions v0.11.0 → v0.15.0) conçu pour voler les clés sécrètes.
Détection rapide (14h47 → 16h21). La v0.16.0 est saine, aucun autre repo touché.
Si vous l’avez téléchargée aujourd’hui ou ces versions : mettez à jour/supprimez ET faites une rotation complète de vos secrets (API, SSH, cloud, .env…).

.@Volexity has discovered in-the-wild exploitation of a #zeroday exploit chain targeting Ivanti Connect Secure VPN appliances (CVE-2026-104935). Beginning October 3, a previously unknown threat actor, UTA0576, chained three vulnerabilities to gain unauthenticated root-level code execution on a fully patched device. Notably, UTA0576 deployed no malware or web shell. Instead, the threat actor re-exploited the device for every command it ran and tampered with logs to cover its tracks, evading Ivanti’s Integrity Checker Tool.
Using its #Volcano memory analysis platform, Volexity analyzed the compromised device’s memory to uncover the full exploit chain and the attacker’s post-exploitation activity, which focused on credential theft, Active Directory reconnaissance, and data exfiltration. Volexity reported these findings to Ivanti through coordinated disclosure.
