Memory-safety defects in the upstream (abandoned) AOSP OpenCORE AAC decoder, shipped unpatched by Samsung TizenRT

Abandoned AOSP OpenCORE AAC decoder has out-of-bounds-write and wild-pointer flaws reachable from attacker-controlled frames, unpatched in Samsung TizenRT.

The OpenCORE AAC decoder in AOSP's abandoned external/opencore tree contains memory-safety defects of the out-of-bounds-write and wild-pointer class. The code is still vendored and built by multiple projects, most notably Samsung's widely deployed TizenRT embedded RTOS. The defects are reachable from untrusted media because an AAC frame is attacker-controlled. The researcher is requesting a CVE ID for the issue.

The gpg.fail aftermath: On responsible disclosure, GPG, and the state of security in 2026 [32:37]

A conference talk recounts GPG vulnerability disclosures, notes several GnuPG flaws remain unpatched, and demonstrates novel bugs live.

A researcher who disclosed multiple GnuPG vulnerabilities before 39c3 in December 2025 reports that several flaws, including one allowing spoofed PGP signatures, remain unpatched. Memory corruption in the basic PGP message parser was properly fixed, but GnuPG maintainer Werner Koch declared a widely-used feature 'harmful' instead of patching it. The talk presents additional novel GPG vulnerabilities and commentary on responsible disclosure and LLMs in security.

GeoServer Zero-Day Targeted in Active Exploitation Attempts, Can Lead to RCE

A CVSS 9.8 SQL injection zero-day in GeoServer's PostGIS datastore enables RCE and drew active exploitation; fixes shipped in versions 3.0.1, 2.28.5, 2.27.6.

A SQL injection flaw in GeoServer's jsonArrayContains function within the GeoTools PostGIS datastore (GHSA-mqjf-5f49-2fjh, CVSS 9.8) was disclosed August 12, 2026, and saw hundreds of exploitation attempts within hours per watchTowr. An attacker-controlled value is interpolated into a PostgreSQL jsonb_path_exists() expression without escaping; with superuser or pg_execute_server_program privileges it escalates to OS command execution via WFS 1.0. GeoServer released versions 3.0.1, 2.28.5, and 2.27.6, and the flaw is a regression of CVE-2023-25158. GeoServer has a history of mass exploitation, including CVE-2024-36401 used for botnets and proxies.

StyleSmuggler: The Magento Zero-Day Behind New Store Attacks

Sansec reports actively exploited Magento/Adobe Commerce zero-day StyleSmuggler enabling unauthenticated RCE and Rust backdoor installation on fully patched stores since September 4.

Sansec discovered StyleSmuggler, an unpatched zero-day in Magento Open Source and Adobe Commerce, affecting all current versions including 2.4.7, 2.4.8 and 2.4.9, with attacks observed since September 4. The two-stage attack poisons Magento's template system via the styles property and executes the injected PHP during 'Payment Transaction Failed Reminder' email rendering, working even when email delivery fails and when sessions are moved to Redis. Successful compromise installs a lightweight Rust backdoor disguised as fc-cache or chronyd that beacons every 60 seconds with 48-byte UDP packets to NTP port 123 at ntp.timesync.to. A second attacker deployed a PHP web shell in product-image cache directories, hidden behind 404 responses unless a correct X-Cache-Token header is present.

Unpatched Magento and Adobe Commerce Zero-Day Exploited to Backdoor Online Stores

Sansec reports active exploitation of an unpatched zero-day, dubbed StyleSmuggler, in Magento and Adobe Commerce, letting attackers backdoor online store servers without authentication.

Sansec disclosed on September 5 that attackers are exploiting an unpatched vulnerability, named StyleSmuggler, in Magento Open Source and Adobe Commerce to achieve unauthenticated remote code execution, with attacks observed starting September 4. All current versions including 2.4.9 are affected, and Adobe has published no advisory, CVE, patch, or workaround, with the next scheduled security release on September 8. Hosting firm Disrex Group independently confirmed two compromised stores (running 2.4.8 and 2.4.7-p2), both breached within the roughly eight-hour window before Sansec's blocking rules went live. The implant is a ~1.9 MB statically linked Rust binary disguised as a Linux kworker process, re-adding a cron entry every five minutes and in one case reading Magento sessions directly from Redis with no outbound traffic.

The V8 flaws were fixed in upstream Chromium source but had not yet reached Chrome stable releases, creating a patch gap that attackers reverse-engineered and weaponized. A China-aligned state-sponsored actor used the kit from August 28 against a small number of US NGOs, mining and commodity trading firms via rapport-building spear phishing, and within days several mostly China-linked espionage clusters adopted BlueMoon. The chain yields full Windows admin privileges from a single phishing click; defenders should patch Chrome and Windows, apply Proofpoint detections and hunt for leftover artifacts.

The analysis notes AI now finds unknown flaws at volumes patching teams cannot absorb and that exploit development time has collapsed, citing defensive efforts like Anthropic's Project Glasswing and OpenAI's Daybreak. Gartner recommends recalibrating cyber risk impact, revisiting risk appetite, demanding stronger vendor security validation, and moving toward faster automated remediation.

Adobe fixes critical Magento zero-day exploited to backdoor servers

Adobe emergency-patches actively exploited max-severity Magento/Adobe Commerce zero-day CVE-2026-75650 (StyleSmuggler), used since Sept 4 to backdoor servers.

Adobe released an emergency hotfix (VULN-39341) for CVE-2026-75650, a max-severity zero-day dubbed StyleSmuggler affecting Adobe Commerce 2.4.4-2.4.9, Adobe Commerce B2B 1.3.3-1.5.3, and Magento Open Source 2.4.6-2.4.9, enabling arbitrary code execution. Sansec reports the flaw has been exploited since at least September 4 to plant a backdoor whose C2 host is disguised as an NTP server, leaving traces like 'Payment Transaction Failed Reminder' emails. A second attacker with unrelated tooling is exploiting the flaw to deploy a 485-byte PHP web shell that collects server details, checks pub/media writability, and exfiltrates data to an oast.site subdomain. Adobe recommends immediate hotpatching plus rotation of all secrets including admin passwords, API keys, database credentials, and SSH keys.
