🚨 First PHP, now Ruby... Memory corruption vulnerabilities in Ruby's regex engine (Onigmo) could lead to RCE in applications that compile regular expressions from untrusted user input. Not just ReDoS. These flaws are also behind the recent GitLab RCE alerts. So... update Ruby! ruby-lang.org/en/news/2026/1… #ruby #rubylang #rails #rubyonrails #cybersecurity

🚨 CONFIRMED: PHP has officially acknowledged another RCE vulnerability, CVE-2026-115560, affecting specific session configurations even after the October 21 patches. A separate issue, not a bypass of the original fixes. A patch is planned. We've updated our defensive toolkit: github.com/syhunt/php2shell-… #php #cybersecurity

We've updated our php2shell-protection toolkit with new findings on post-patch PHP security risks, additional hardening recommendations, and expanded credits to @acd421 for his research. No exploit code or PoC links. The focus remains on defense. #php #cybercurity github.com/syhunt/php2shell-…

🚨 UPDATE: A public PoC demonstrates RCE on PHP 8.5.12, even after the October 21 security patches. The attack is separate from the patched php2shell CVEs and requires specific session configurations and application weaknesses. Our earlier concerns about PHP session handling remain relevant. We've updated php2shell-protection with additional hardening guidance. #php #cybercurity github.com/syhunt/php2shell-…

As if PHP2Shell wasn't enough for one day... now GitLab. 😅 🚨 CRITICAL GITLAB ALERT (CVSS 10.0) CVE-2026-110264 could allow unauthenticated RCE on self-managed GitLab servers. ⚠️ Potentially affects 12 years of releases, dating back to 2014. Patches available. Update immediately! docs.gitlab.com/releases/pat… #gitlab #cybersecurity

Patch immediately, but continue monitoring emerging research. The reported crash warrants investigation, not a premature declaration that PHP 8.5.12 remains remotely exploitable. nitter.cf/FelipeDaragon/status/2…
🚨 UPDATE: PHP 8.5.12 may still be vulnerable to php2shell! Researchers are reporting a successful double-free trigger on the newly patched release. ⚠️ The official fixes may be incomplete. A crash alone doesn't confirm RCE, but this deserves urgent investigation. Don't assume you're safe just because you've patched. #php4shell #php #cybersecurity nitter.cf/_annieversary/status/2…

Readers added context they thought people might want to know
The original post has since been edited to specify that this was about an unrelated vulnerability that the user had discovered, not the recently patched vulnerability. fedi.katze.sh/@elise/1174793…

🚨 UPDATE: PHP's official advisory confirms the php2shell vulnerabilities and session upload-progress attack path, but not that multipart blocking provides complete protection. We've updated our repo with official findings and additional hardening measures. Patching remains essential. github.com/syhunt/php2shell-… #php #Cybersecurity #php2shell

ありがたい!が、環境によっては注意が必要。 php2shellの暫定策として「multipart/form-dataのPOSTをApacheで止める」ルールを入れるなら、判定をPHPと同じ切り方に揃えないと漏れる。 PHPはContent-Typeを「;」「,」「空白」のどれでも区切り、小文字にしてから multipart/form-data と比べる(main/SAPI.c)。syhunt/php2shell-protection の初版の正規表現はカンマを見ておらず、公開から約2時間後の修正で [;,[:space:]] になった。READMEは効果の限界まで正直に書いてある。使うなら修正後の版を。 自分の環境に当てはめて引っかかったのは3点。 ・AllowOverride None だと .htaccess は読まれない。vhostに書く ・<If> の %{CONTENT_TYPE} はレスポンス側。リクエストは %{HTTP:Content-Type} ・同梱の checkblock.php はHostヘッダ宛にPOSTするので本番に残さない 2件目の根本原因はまだ公式に出ていない。multipart以外の経路があるかは、修正版の差分で確かめてください。 github.com/syhunt/php2shell-…
We've released php2shell-protection, an emergency Apache mitigation and testing toolkit for CVE-2026-109618 / CVE-2026-109619. ⚠️ Not based on official vulnerability details. This is a precautionary measure based on information circulating in the security community and zero-day PoC material we've obtained and reviewed. It blocks multipart POST requests before they reach PHP. Not a substitute for patching. github.com/syhunt/php2shell-… #php #Cybersecurity

For those mitigating remember this is still primitive mitigations the ultimate is updating as soon as its released. Some parts were Redacted for safety to the ecosystem as a whole. These primitive mitigations still give you a head start on what attackers likely already recreated.

We just released an emergency mitigation and testing toolkit for CVE-2026-109618 & CVE-2026-109619. This is a precautionary, community-driven effort based on preliminary info and privately reviewed zero-day PoC material, not official vuln. guidance #php nitter.cf/FelipeDaragon/status/2…
