The FBI warned that the FortiBleed campaign has compromised more than 86,000 Fortinet devices and is still locking out admins, Atlassian's CVE-2026-21589 is being exploited within hours of a public PoC, and SonicWall patched a maximum-severity SMA1000 flaw.

FBI and Secret Service warn FortiBleed has compromised 86,644 Fortinet devices Confirmed
A joint FBI and Secret Service advisory says FortiBleed remains active against internet-facing Fortinet FortiGate firewalls and SSL VPN gateways, with reporting that more than 86,644 devices have been compromised across 194 countries. The campaign exploits reused or leaked credentials and legacy SHA-256 password storage to harvest authentication data, and victims report being locked out of their accounts. Admins should reset unique credentials, remove internet exposure where possible, hunt for unauthorised access, and read the IC3 advisory for indicators.

Attacks exploit Atlassian CVE-2026-21589 (CVSS 9.3) within hours of public PoC Confirmed
Atlassian patched CVE-2026-21589, a critical arbitrary file access flaw rated 9.3, affecting eight self-hosted Data Center products including Jira, Confluence, Bitbucket and Bamboo. Unauthenticated attackers can read files in each product’s web application root directory if they know the exact path, and SANS ISC plus news reports say scanning and exploitation attempts began within about two hours of public technical details appearing. Customers running affected versions should patch immediately and review logs for suspicious file-access requests.

SonicWall patches maximum-severity SSRF flaw in SMA1000 appliances Confirmed
SonicWall released hotfixes for four flaws in its SMA1000 remote-access appliances, the most serious rated 10.0 for a pre-authentication server-side request forgery that could let an unauthenticated attacker send requests through the appliance and reach internal functions. SonicWall says it has no evidence that any of the four flaws is being exploited. Organisations that expose SMA1000 gateways should apply the hotfixes promptly.

Unpatched critical LMCache flaw allows unauthenticated remote code execution (CVE-2026-105192) Confirmed
JFrog disclosed CVE-2026-105192, rated 9.8, in LMCache, an open-source KV-cache layer used to speed up LLM servers such as vLLM. In multiprocess mode the cache opens an unauthenticated ZeroMQ socket and unpacks a message field with pickle, so a single crafted message can run code as the LMCache process, which runs as root on the project’s container images. No fixed version exists, so operators should keep the multiprocess port (default 5555) on localhost or a trusted network and avoid exposing it on a routable address.

PoeLLM malware infects 3,400+ exposed AI servers to build a cryptomining botnet Confirmed
Researchers describe a campaign tracked as Canto Incognito that uses a malware family called PoeLLM to compromise exposed AI and LLM infrastructure, install cryptocurrency miners and turn the servers into scanners and attack launchpads. More than 3,400 servers have reportedly been infected. Operators of internet-facing AI and model-serving services should check for unauthorised miners, close exposed ports and review outbound scanning activity.

Attackers hijack .gh, .sl and .as registries and obtain certificates for Google domains Confirmed
Google said attackers compromised third-party operators of the Ghana (.gh), Sierra Leone (.sl) and American Samoa (.as) country-code registries, changed authoritative DNS records and obtained unauthorised HTTPS certificates for several Google domains. Google’s own systems were not breached, but any domain under those ccTLDs was put at risk because a valid certificate lets an attacker impersonate a site over encrypted connections. Organisations that use those extensions should review their DNS records and watch for certificate misuse.

Europol warns crypto wallets are the primary quantum-computing risk Confirmed
Europol and EU law enforcement agencies said exposed private keys, not blockchains themselves, are the main quantum risk for crypto, urging developers, exchanges and users to begin phased post-quantum migration now. A separate report weighs the risk of data stolen today being decrypted later. The warning is forward-looking guidance rather than a report of an active attack.
