An attacker used stolen credentials and an MFA bypass to steal tax data on 678,000 individuals from France's tax authority DGFiP.
France's General Directorate of Public Finances (DGFiP) disclosed that intrusions into its portals exposed tax data, including reference tax income, family quotient, withholding tax rate, and business identifiers such as company name and SIREN number, on 678,000 individuals and professionals. An attacker using the alias 'ZeroBytes' claimed credit on a cybercrime forum and offered a stolen database for sale, claiming the portal contains data on roughly 20 million citizens. DGFiP suspended the affected accounts, notified the CNIL, and is working with ANSSI and the finance ministry's security office; it said the main online tax portals and their login credentials were not compromised.
Hackers stole personal and tax data of 678,000 individuals and businesses from France's tax agency DGFiP, prompting a Paris criminal investigation.
France's Directorate-General for Public Finances (DGFiP) confirmed a sophisticated cyberattack exposed data on 678,000 users of the tax system, including income figures, tax rates and family circumstances for individuals and SIREN registration data for businesses. The Paris prosecutor's cybercrime unit opened a probe and referred it to the French anti-fraud office OFAC after a threat actor claimed the breach in late June. Officials stressed the stolen data does not grant access to secure accounts on impots.gouv.fr, and taxpayer notification begins Monday with warnings about identity theft and fraudulent follow-up requests. The incident follows recent breaches at the ANTS documents agency and the INSEE statistics authority.

Unauthenticated Path Traversal RCE in Broadcom VMware vCenter Server Syslog
CVE-2026-59310 is a directory traversal (CWE-22) vulnerability in the Syslog server component of VMware vCenter Server, rated critical at CVSS 9.8. It can be triggered over the network without authentication or user interaction, allowing a malicious actor with network access to vCenter to achieve arbitrary code execution. An attacker who exploits it gains code execution on the vCenter appliance, and reported campaigns show it has been used to establish persistent remote access and, by a suspected China-nexus actor, to deploy Babuk ransomware. Any organization running an affected version of vCenter Server is exposed, especially where the management interface is reachable from the internet; the available data does not specify affected version ranges. Exploitation is confirmed in the wild: CISA added the flaw to its Known Exploited Vulnerabilities catalog on 2026-08-18, it was reportedly exploited just five days after disclosure, and EPSS estimates a 45.9% probability of exploitation within 30 days (99th percentile).

Unsafe Reflection RCE in PaperCut NG/MF, Chained with Auth Bypass in Attacks
CVE-2026-82078 is an unsafe dynamic class loading flaw (unsafe reflection, CWE-470) in the database connection utilities of PaperCut NG and PaperCut MF: the software instantiates a database driver class based on a configurable driver name without validating it against an allowlist of approved drivers. An attacker who can manipulate system configuration parameters can point that setting at classes of their choosing, causing the server to execute arbitrary Java bytecode residing on the application classpath in the security context of the PaperCut server process. On its own the issue is rated 9.4 (Critical) with high privileges required, but when chained with the companion authentication bypass CVE-2026-81578 it yields unauthenticated remote code execution on the print-management server. All PaperCut NG and MF deployments are in scope; affected version ranges were not specified in the available data, so administrators should consult PaperCut's advisory for fixed versions. The flaw is confirmed exploited in the wild as a zero-day: it was added to CISA's KEV catalog on 2026-08-31, and public reporting describes an AI-orchestrated campaign that compromised PaperCut servers at roughly 395 organizations (~440 servers), with EPSS currently at 1.7% (76th percentile).
Missing Authentication for Critical Function in PaperCut NG/MF Web Interface
CVE-2026-81578 is an improper access control flaw (CWE-305) in the web management interface of PaperCut MF and PaperCut NG in which administrative requests from unauthenticated remote users trigger backend actions before access validation completes. An attacker can invoke administrative functions without logging in, allowing modification of certain system configurations. When chained with CVE-2026-82078 (unsafe dynamic class loading), the flaw has been used to achieve unauthenticated code execution. Any organization running PaperCut NG/MF, particularly servers whose web management interface is reachable from the internet or untrusted networks, is affected. The vulnerability was added to CISA KEV on 2026-08-31 and is being exploited in the wild as part of an AI-orchestrated campaign that compromised roughly 395–440 organizations.
Use-After-Free Local Privilege Escalation in Microsoft Windows WinSock AFD Driver
CVE-2026-68820 is a use-after-free (CWE-416) in the Windows Ancillary Function Driver for WinSock (afd.sys), the kernel component that handles Winsock socket operations. A local, authenticated attacker can trigger the memory corruption through crafted socket activity, and the high attack-complexity score (AV:L/AC:H/PR:L) indicates exploitation requires a specific, likely race-sensitive sequence of operations. Successful exploitation elevates privileges to SYSTEM, giving the attacker full control of the host, and public reporting describes deployment of a backdoor after privilege escalation. Virtually every Windows 10, Windows 11, and Windows Server (2012-2022) installation ships this driver, so the affected population is essentially the entire supported Windows installed base. The flaw is being exploited in the wild: CISA added it to the KEV on 2026-08-11, Microsoft fixed it in the August 2026 Patch Tuesday release, and reporting ties active exploitation to North Korea's Lazarus group, who paired the zero-day with fake job-offer lures.

Authentication Bypass in Apple macOS Screen Sharing
CVE-2026-65400 is a critical (CVSS 9.8) improper authentication flaw (CWE-287) in Apple macOS's Screen Sharing service, caused by an authentication state-management defect. An attacker who can reach a vulnerable Mac's Screen Sharing service over the network can authenticate without valid credentials, gaining full remote access with high impact to confidentiality, integrity, and availability. All three currently supported macOS branches are affected: Sequoia, Sonoma, and Tahoe, in versions prior to the fixed releases. The flaw is being actively exploited on the internet, with public reporting that attackers use the bypass to deploy Monero cryptominers, and CISA added it to the Known Exploited Vulnerabilities catalog on 2026-08-18. EPSS estimates a 9.9% probability of exploitation within 30 days (95th percentile).

Privilege Escalation in Microsoft Active Directory Domain Services
CVE-2021-42287 is an elevation-of-privilege vulnerability in Microsoft Active Directory Domain Services (AD DS) affecting multiple supported Windows Server releases. An attacker with any low-privileged domain account can trigger it — commonly in combination with the related sAMAccountName spoofing flaw CVE-2021-42278 — by manipulating account name attributes so the Kerberos Key Distribution Center issues tickets that grant rights normally reserved for domain controllers. The result is escalation from a standard user to domain administrator, giving the attacker full control over the Windows domain, a capability that is directly useful for ransomware deployment and data theft. Any organization running Active Directory on the affected Windows Server versions is exposed, which amounts to essentially every enterprise Windows network. The flaw is actively exploited: it was added to CISA's Known Exploited Vulnerabilities catalog on 2022-04-11 with known ransomware use, and EPSS assigns it a 77.2% probability of exploitation within 30 days.

Privilege Escalation via sAMAccountName Spoofing in Microsoft Active Directory
CVE-2021-42278 is an elevation of privilege flaw in Microsoft Active Directory Domain Services (AD DS) caused by improper handling of changes to a computer account's sAMAccountName, allowing an attacker to 'spoof' a domain controller's name. A low-privileged authenticated user who can create or rename computer accounts (possible by default for ordinary domain users under MachineAccountQuota) renames a machine account to match a domain controller, obtains a Kerberos ticket for that name, and — typically chained with the related flaw CVE-2021-42287 — impersonates the domain controller to gain domain administrator rights. Successful exploitation yields full control of the Active Directory domain, which attackers, including ransomware operators, use to move laterally and deploy ransomware. Any organization running Active Directory on the affected Windows Server releases is exposed, though only servers with the AD DS role (domain controllers) reachable by an attacker with valid domain credentials are directly exploitable. The flaw is under active exploitation: it was added to CISA's Known Exploited Vulnerabilities catalog on 2022-04-11 with known ransomware use, and EPSS assigns a 73.3% probability of exploitation within 30 days.

Unauthenticated Arbitrary File Read in Ruby on Rails Active Storage
CVE-2026-66066 is a flaw in Active Storage (part of Ruby on Rails' Action Pack) in which libvips operations that are marked unsafe for untrusted content are not disabled, so a crafted upload can invoke such an operation on the server. It is triggered when an unauthenticated attacker uploads a maliciously crafted image to a Rails application that is configured to use libvips and accepts image uploads from untrusted users. Successful exploitation lets the attacker read arbitrary files accessible to the Rails process, including environment variables and application secrets; leaked credentials such as secret_key_base or external-service tokens can be leveraged for remote code execution or lateral movement. Affected applications are those running Rails 7.2.x, 8.0.x or 8.1.x before the patched releases 7.2.3.2, 8.0.5.1 and 8.1.3.1, provided Active Storage with libvips is in use. Public exploit code is not yet documented, but news reports describe active attacks against Rails apps (a campaign referred to as "KindaRails2Shell"), EPSS assigns a 27.9% probability of exploitation within 30 days (98th percentile), and the flaw is not yet listed in CISA KEV.

Unauthenticated SSRF in SonicWall SMA1000 Appliances
CVE-2026-15409 is a server-side request forgery (SSRF, CWE-918) in the Appliance Work Place interface of SonicWall SMA1000 series appliances. A remote, unauthenticated attacker can trigger the flaw over the network, causing the appliance to issue requests to attacker-influenced or unintended internal locations. Because the CVSS vector scores scope-changed impacts on confidentiality, integrity, and availability, the SSRF is assessed as capable of reaching sensitive internal services, and reporting indicates it is being used alongside a second SMA1000 zero-day in what may be an exploitation chain. Affected organizations are those running SMA1000 appliances, including SMA 6210, SMA 7210, and SMA 8200v models, which typically act as internet-facing remote-access/VPN gateways. Exploitation is confirmed in the wild: the flaw was added to CISA's KEV on 2026-07-14, ransomware use is known, and EPSS assigns an 83.7% probability of exploitation within 30 days, though no public PoC is available.
