insomnisec.comPHP2Shell: Critical PHP Flaws Let Attackers Take Over Web Servers Without a LoginPHP has released emergency fixes for PHP2Shell, two critical flaws (CVE-2026-109618 and CVE-2026-109619, CVSS 9.2) in the PHP engine itself that can let an unauthenticated attacker run code on a web server. Amazon says attackers were already trying to exploit them on October 17, four days before the fix, and attempts have since climbed into the millions. Update to PHP 8.5.12, 8.4.27, 8.3.36, or 8.

And ... I was hoping things would look up, but no. Capcom just published an apology for a data breach. This, as you probably can tell, is the translated version:

"It has been found that some of your information has been leaked to the outside world due to unauthorized access by a third party in the online member service 'CAPCOM ID' (*1) operated by our company. We deeply apologize for the inconvenience and concern caused to our customers and related parties" https://www.capcom.co.jp/ir/news/html/261022.html

A QPACK implementation flaw can turn a tiny HTTP/3 request into a serious memory exhaustion problem.

FoxIO’s Header Accordion research reports up to 4,064× memory amplification in Bun.

The key issue: compressed headers on the wire can expand into massive allocations during QPACK decompression.

Skoro @lacze dalej nie potrafi odpuścić i publikuje kolejne wielostronicowe elaboraty, czas napisać to jasno i definitywnie. Twierdzisz, że "działasz bez parcia na szkło" i "nie dla ego", a właśnie napisałeś esej w obronie własnego wizerunku, przy okazji publicznie przyznając, że to Ty pierwszy napisałeś do mnie na priv, bo mój blog zrobił na Tobie wrażenie. Jeśli to nie jest definicja urażonego ego, to nie wiem, co jest.

Zarzucasz mi hipokryzję w sprawie Brave i Safe Browsing. Po raz kolejny nie zrozumiałeś mojego wpisu. W mojej konfiguracji owszem, wspominam o wyłączeniu Safe Browsing, ale jako o ŚWIADOMYM, OPCJONALNYM KOMPROMISIE. Jeśli ktoś woli ukryć IP przed Google kosztem utraty ochrony, to jego wybór. Różnica polega na tym, że ja prezentuję to jako trade-off, a Ty twierdzisz, że NextDNS to ZAMIENNIK Safe Browsing. To bzdura, bo NextDNS działa tylko na poziomie domen i nie widzi ścieżek URL. Twoja filozofia "prywatność ponad bezpieczeństwo" jest absurdalna. IEEE wprost stwierdza, że bezpieczeństwo jest warunkiem wstępnym prywatności.

Nazywasz mnie kopistą. Owszem, wzorowałem się na dobrych źródłach, bo na tym polega rzetelna kwerenda. Różnica między nami polega na tym, że ja te źródła rozumiem i wyciągam z nich wnioski. Ty natomiast tłumaczysz cudze teksty DeepL-em i nie rozumiesz nawet własnych cytatów.

Zastanawia mnie też Twoja obsesja. Kto normalny stalkuje kogoś z innych kont i trybu incognito, mimo że został zablokowany i olany? Piszesz wielostronicowe dokumenty, bo Twoje kruche ego nie potrafi przyjąć do wiadomości, że ktoś po prostu Cię zignorował.

A na koniec mały dodatek, który pokazuje kwintesencję Twojego "bezpieczeństwa". Pouczasz wszystkich o OPSEC i Zero Trust, a jednocześnie trzymasz "telefon obywatela" z usługami Google, mObywatelem i aplikacjami bankowymi w torbie Faradaya. Wyraźnie nie wiesz, że telefon w torbie nadal zbiera telemetrię offline. Gdy tylko go wyciągniesz, żeby zalogować się do banku, złapie sieć i natychmiast wyśle cały ten bufor do Google. Twój cały wypracowany wizerunek z GrapheneOS pada w tym jednym momencie.

To mój ostatni wpis na ten temat. Zamykam ten rozdział u siebie. Idę robić rzeczy, które mają realną wartość. EOT.
