ATTACKS & VULNERABILITIES

TLDR InfoSec

OVER 600 LARAVEL APPS EXPOSED TO REMOTE CODE EXECUTION DUE TO LEAKED APP_KEYS ON GITHUB

Cybersecurity researchers discovered that leaked Laravel APP_KEYs from GitHub can enable remote code execution attacks. Over 260,000 APP_KEYs were extracted from GitHub, with more than 600 vulnerable applications identified. When attackers obtain these encryption keys, they can exploit deserialization flaws to execute arbitrary code on servers, compromising data and infrastructure security.

ROLLING OUT SANTA WITHOUT FREEZING PRODUCTIVITY: TIPS FROM SECURING FIGMA'S FLEET

Figma successfully deployed Santa, an open-source binary authorization tool, across all employee laptops by running it in monitoring mode for months to build a comprehensive allowlist based on actual usage patterns. It minimized user disruption through a custom Slack-based self-service system that allows employees to quickly approve blocked applications after automated security checks, as well as an escape hatch that enables temporary monitoring mode during rollout. The phased deployment began with users having zero unknown binaries and gradually expanded to 100% coverage over three months, utilizing automated package rule generation and group-based policies to handle edge cases, such as developer tools.

HOW I FOUND A BYPASS IN GOOGLE'S BIG ANTI-ADBLOCK UPDATE

The author discovered a Chrome bug that allowed MV3 extensions to bypass Google's removal of webRequestBlocking (which kills adblockers) by exploiting legacy JavaScript bindings and creating fake webRequest events with spoofed WebView IDs. The exploit worked by using the constructor of existing webRequest events to create new events with the opt_webViewInstanceId parameter set, which skipped permission checks for webRequestBlocking since the browser never verified if the extension had WebView permissions. Google patched the vulnerability in Chrome 118 by adding proper permission validation, although it didn't award a bounty since it didn't expose new data to extensions.

“LOCALHOST TRACKING” EXPLAINED. IT COULD COST META 32 BILLION

Meta deployed “localhost tracking” that bypassed Android security protections by using its mobile apps to listen on local network ports while tracking scripts in web browsers sent user identifiers via WebRTC, linking anonymous browsing activity to real Facebook/Instagram identities even when users employed VPNs, incognito mode, and deleted cookies. The scheme affected 22% of the world's most visited websites and collected complete browsing histories, purchases, and behavioral patterns without proper consent across billions of users over multiple years. Meta now faces potential fines of €32 billion under GDPR, DSA, and DMA regulations for violating data protection, personalized advertising restrictions, and rules governing the combination of cross-platform data.

SMM CALLOUT VULNERABILITIES IDENTIFIED IN GIGABYTE UEFI FIRMWARE MODULES

Four SMM callout vulnerabilities (CVE-2025-7026 through CVE-2025-7029) were found in Gigabyte UEFI firmware, allowing attackers with admin privileges to execute code in System Management Mode, bypassing OS protections and potentially disabling Secure Boot and Intel BootGuard. These flaws result from improper validation of CPU registers and pointers in SMI handlers, enabling malicious control over SMRAM writes and flash operations. Although they were previously fixed by AMI, these issues reappeared in Gigabyte's firmware, so users should urgently update to the latest UEFI from Gigabyte's support site.
