PostgreSQL Patches 52 Flaws, Including 22-Year-Old Bug Enabling Authenticated RCE

PostgreSQL Patches 52 Flaws, Including 22-Year-Old Bug Enabling Authenticated RCE

Nov 13, 2026 Vulnerability / Database Security
A type confusion flaw in PostgreSQL lets a database user who can create objects run code on the server. Updates released yesterday fix it, along with 51 other security flaws. Full protection from this flaw also requires rebuilding any C-language extensions installed on the server. The flaw, tracked as CVE-2026-6460 , has a CVSS score of 8.8. Any code run this way has the rights of the operating system user that runs PostgreSQL. All versions before 18.7, 17.12, 16.16, 15.20, and 14.25 are affected. The PostgreSQL Global Development Group, which publishes the database's releases, has not reported any attacks using the flaw. CISA's assessment in the CVE record also lists exploitation as none. The flaw involves composite types, which are types built from named fields, each with its own data type. A field's type can be changed while older values of that type are still held in other parts of the server. The server could then read an old value as if it had the new type. T...
New Mior and Skyfall Attacks Let Rogue Cloud Hosts Steal Secrets From AMD SEV-SNP VMs

New Mior and Skyfall Attacks Let Rogue Cloud Hosts Steal Secrets From AMD SEV-SNP VMs

Nov 13, 2026 Vulnerability / Hardware Security
Two attacks made public this week allow a malicious host to read data inside AMD SEV-SNP-protected virtual machines (VMs), which are built to keep the server's operator out. One of them, Mior , can also modify a VM's memory and fake the signed report confirming which software it runs. Both need control of the server's hypervisor, and Mior also needs control of the server's BIOS. Researchers showed both in lab tests on AMD EPYC server processors. AMD, which makes the processors, lists SEV firmware for Mior and microcode for Skyfall , both dated August 12. It plans to give server makers platform firmware in November for Skyfall and in December for Mior, and fixes for embedded chips later. Customers are told to get the BIOS update from their server maker. SEV-SNP brings confidential computing to AMD EPYC server processors. It uses hardware-enforced memory encryption and access control to protect a VM, even from the host's hypervisor. The ETH Zurich team behin...
Trezor Confirms Hidden Implants in CryptoBilis-Sold Wallets That Can Steal Recovery Phrases

Trezor Confirms Hidden Implants in CryptoBilis-Sold Wallets That Can Steal Recovery Phrases

Nov 13, 2026 Cryptocurrency / Supply Chain
Three Trezor Safe 5 wallets bought from the reseller CryptoBilis contain an implant, an extra circuit board that can copy their recovery phrases, hardware wallet maker Trezor said yesterday. The implant reads the phrase from the wallet's screen and sends it over the mobile network to a server controlled by the attackers. The company examined one of the wallets in its lab, identified the other two from photos their owners sent, and has had no reports of lost funds. A firmware update released earlier this week, version 2.13.1, stops the implants found so far from capturing anything on wallets that run it, the company said, but “the update can’t protect a wallet backup that was captured before it.” The company has not changed its advice to anyone who bought a Trezor from CryptoBilis since March, including from the reseller's stores on Tokopedia and Shopee: Move your funds to a new wallet with a new recovery phrase. Restoring the old phrase on another wallet does not ...

Hackers Exploit PHP2Shell Flaws in Check Point Gateways to Deploy TSGA Backdoor and Wipe ESXi Files

Hackers Exploit PHP2Shell Flaws in Check Point Gateways to Deploy TSGA Backdoor and Wipe ESXi Files

Nov 13, 2026 Vulnerability / Cyber Espionage
An unknown threat actor has been observed targeting unpatched Check Point Security Gateways to obtain initial access via the PHP2Shell vulnerabilities and then a previously unreported local privilege escalation flaw in Gaia OS  to deploy a backdoor called TSGA . The activity, detailed by Check Point, began on October 30, 2026, and targeted Israeli organizations, with a broader follow-up wave on November 2, 2026, that targeted organizations across multiple countries and sectors. Some of the organizations singled out in the first wave have also been at the receiving end of destructive actions that include the deployment of wiper malware. "PHP2Shell provided initial access, followed by privilege escalation through the DynamicCLI interface, tracked as CVE-2026-123039 ," Check Point said. "The attackers then deployed PHP web shells, the persistent TSGA backdoor, and its embedded TSProxy networking component." "The attackers pivoted from the gateway to a VMw...
Hackers Exploit N-central Flaws to Infect 21 Servers, Including 19 Running Hotfix 2

Hackers Exploit N-central Flaws to Infect 21 Servers, Including 19 Running Hotfix 2

Nov 13, 2026 Vulnerability / Cyber Attack
N-able on Thursday said it's taking additional precautions in the wake of public disclosure of a new set of flaws tracked as 4EverAble2Shell and Agent2Shell . "We are restricting certain N-central features and integrations," the company said in a Thursday update. "These measures may affect some functionality, but we believe taking additional precautions while remediation is completed is the right action to protect our partners and their customers." The following actions have been applied to Hosted environments - Legacy API is turned off by default in the product. Intune integration has been turned off while additional protections are implemented and validated. Hosted customers are also being recommended to follow N-able's previous guidance to upgrade Agents and Probes on N-central version 2026.4 HF1 and above, as the update introduces changes in how the Probe and Agent communicate. "N-able N-central 2026.4 HF1 updates legacy componen...
