Odaily Report: Due to a severe security vulnerability exposed in the widely used PHP programming language, multiple government websites across Europe and other regions were forced offline on Wednesday, with website operators taking emergency measures to protect system security. The PHP development team announced the discovery of two severe security vulnerabilities on Tuesday local time, urging users to update immediately once fix patches are released. The PHP team stated on Wednesday that new versions addressing the vulnerabilities have been officially released.

However, as reports emerged that hackers were exploiting the vulnerabilities to breach websites, government agencies in countries including the Netherlands and Finland had already proactively shut down some websites before the patches were released. PHP is one of the most widely used programming languages on the internet, powering website platforms such as WordPress, Drupal, Joomla, and Magento.

According to data from website technology tracking firm W3Techs, approximately 75% of websites whose programming languages can be identified use PHP. About 43% of websites worldwide are powered by WordPress, spanning blogs, small business sites, government portals, e-commerce platforms, and news websites. This security incident has caused widespread disruptions to websites across multiple European countries. The Port of Rotterdam in the Netherlands, the government portal Overheid.nl, the Royal Dutch Football Association (KNVB), the websites of the country's five major political parties, and multiple hospital websites have all been temporarily shut down.

Odaily reports: The Polkadot Community Foundation has issued a security advisory stating that versions 3.0.1, 3.0.3, 3.0.4, and 3.0.5 of the third-party wallet Fearless's browser extension contain malicious code that may send private keys to attacker servers when users unlock their wallets. The relevant code was active during various periods between February 2025 and October 10, 2026.

Currently, 8 users have reported unauthorized transactions potentially related to this vulnerability, involving 17,286 DOT.

The Polkadot Foundation reminds users who have used the above extensions since February 2025 to treat all accounts within them as compromised, generate new keys using other wallets, and transfer assets as soon as possible. Simply switching wallet applications, changing passwords, or reinstalling the extension will not eliminate the risk.

Upon inspection, no related malicious code was found in the Fearless Android and Apple mobile versions; however, if the mobile wallet has previously imported the same keys used by the browser extension, those keys should still be considered compromised.

Odaily reports that Solana's first major consensus upgrade, Alpenglow, went live on mainnet around 13:54 UTC on Wednesday. The upgrade aims to reduce transaction finality time from approximately 12.8 seconds to about 150 milliseconds, a reduction of roughly 99%.

In the first phase of the upgrade, Votor will replace the existing voting and finality confirmation mechanism with direct validator voting and a certificate-based system; subsequent phases will introduce the Rotor block data dissemination protocol, replacing Turbine. At the time the upgrade launched, Solana mainnet transaction finality was 6.6 seconds, with throughput of 4,721 transactions per second.

Alpenglow will replace Solana's existing TowerBFT consensus model. Validators are expected to continue developing Agave 4.5, an upgrade plan that would increase the number of accounts supported by versioned transactions from 64 to 96, currently scheduled for launch in December 2026.

Odaily reports: Blockchain security firm CertiK stated that although Google, Apple, and Microsoft have blocked 8 affected certificates issued by Indian digital certificate authority eMudhra, crypto trading bots and exchange applications may still be exposed to related vulnerability risks, as browser remediation measures may not cover software that uses independent security systems.

Peiyu Wang, Senior Director of Digital Asset Security at CertiK, noted that attackers could exploit compromised certificates to impersonate exchanges, wallet interfaces, and APIs, replace deposit addresses, or trick users into approving malicious transactions. However, such attacks would also require intercepting or redirecting network traffic, and the compromised certificate authority keys alone cannot expose wallet private keys. Crypto service operators should update their software and certificate trust stores, and confirm that their applications reject the affected certificates. (Cointelegraph)

Odaily: Bastion Trading, a major shareholder holding approximately 9.99% of SkyAI (Nasdaq: SKYA), has issued a statement demanding that Executive Chairman Paul K. Danner III and several directors publicly explain the decision-making process behind the liquidation of the company's entire SOL reserve and the approval of the cash tender offer, and calling for a higher offer price and stronger disclosure of conflicts of interest. Bastion Trading noted that SkyAI launched its tender offer on October 16, 2026, but failed to adequately address its previously raised corporate governance concerns; just one month earlier, the company had still stated that it held more than 2 million SOL and reaffirmed its Solana digital asset treasury (DAT) strategy.

Bastion Trading demands that the tender offer price be raised from $3 per share to at least $3.5 per share, and that the maximum acquisition ratio of pre-funded warrants be increased from 95% to 100%; it also requires that strategic advisor warrants be excluded from the scope of the offer, that the securities and potential gains held by directors, officers, and related parties be disclosed, and that information including the SOL sale transactions, the company's balance sheet, and the basis for the tender offer pricing be published. The firm also stated that if directors cannot demonstrate that they fulfilled their independent oversight duties, they should resign voluntarily; otherwise, a special shareholders' meeting should be convened to let shareholders decide the composition of the board. The above content represents demands unilaterally raised by Bastion Trading, and the relevant response from SkyAI's board has not been reflected in the provided materials. (Globenewswire)
