Adobe has released patches for seven critical, top-rated code execution vulnerabilities in its ColdFusion web application platform and Campaign Classic marketing tool. Six of the flaws affect ColdFusion 2025 and 2023 and stem from unrestricted file uploads, improper input validation, and path traversal, each allowing arbitrary code execution; the seventh, in Campaign Classic, is an authorization flaw with the same impact on on-premises installations. All can be exploited in low-complexity attacks without user interaction. Adobe says it is not aware of any active exploitation but assigned its highest deployment priority, urging admins to patch quickly, since ColdFusion has repeatedly been targeted by attackers and ransomware crews.
Researchers at Synacktiv disclosed an unpatched flaw in Argo CD, the popular GitOps tool for deploying to Kubernetes, that can lead to full cluster takeover. The problem is in repo-server, the component that turns Git repository files into Kubernetes manifests: its internal gRPC service requires no authentication, so anyone who can reach it on the cluster network can send a crafted request and run commands. Synacktiv reported it about eighteen months ago, but there is still no fix and no CVE, so it went public to warn users. With no patch, the practical defense is network isolation using Kubernetes network policies.
Researchers at Cato AI Labs detailed two flaws, dubbed DuneSlide, in the AI code editor Cursor that let a prompt-injection attack break out of the sandbox Cursor uses to contain the commands its agent runs. The attacker never types anything: they plant instructions in content the agent reads on the user's behalf, such as a connected MCP service or a web page. One flaw abuses a working-directory setting to get an attacker path added to the allowed-write list, letting injected commands overwrite the sandbox helper itself and then run with no sandbox. Both are rated 9.8 and are fixed in Cursor 3.0; every earlier version is affected, so users should update.
A critical flaw in Progress Kemp LoadMaster lets an unauthenticated attacker run commands as root on the appliance by sending a crafted request to its API. Rated 9.8, the bug (CVE-2026-8037) sits in a function meant to sanitize input before it reaches a shell command, and LoadMaster's position as an edge load balancer and application delivery controller makes a pre-authentication flaw especially dangerous, since it can turn a protective choke point into a direct foothold. Progress patched it in early June, and researchers at watchTowr published a full technical write-up with a working proof-of-concept on June 29. No exploitation has been reported yet, but Progress also makes MOVEit, a past mass-exploitation target.
CISA has updated its Known Exploited Vulnerabilities catalog to warn that ransomware gangs are now exploiting BlueHammer, a Microsoft Defender privilege-escalation flaw. The bug (CVE-2026-33825) lets a local attacker who already has a foothold escalate to SYSTEM by abusing Defender's file-remediation logic, giving them access to password hashes and the control needed to disable defenses and prepare systems for encryption. It was leaked with proof-of-concept code by a researcher in early April as a protest over Microsoft's disclosure process, exploited as a zero-day, then patched on April 14. It cannot be used for remote compromise on its own, but it strengthens attackers after initial access.
Citrix has released fixes for six vulnerabilities in NetScaler ADC and NetScaler Gateway, including a high-severity memory-disclosure flaw that researchers place in the same class as the 2023 CitrixBleed bug. That flaw (CVE-2026-8451, rated 8.8) leaks small amounts of memory through malformed SAML requests and shares a root cause with an earlier NetScaler bug that was exploited within days of disclosure. The bulletin also covers an unauthenticated arbitrary file read and several denial-of-service issues, with CVSS scores from 6.9 to 8.8. No exploitation has been reported yet, but NetScaler appliances have drawn more than 20 entries on CISA's exploited-vulnerabilities list in three years, several used in ransomware.
Attackers have begun exploiting a critical flaw in Oracle E-Business Suite, the financial and operations platform used by large enterprises, threat intelligence firm Defused reports. The bug (CVE-2026-46817), rated 9.8, sits in the File Transmission component of Oracle Payments and lets an unauthenticated attacker with HTTP access take over the system through a low-complexity attack. Oracle patched it in its May 2026 update, but exploitation began over the weekend despite no public proof-of-concept existing, meaning attackers built their own. Observed payloads attempt to read sensitive system files. Shadowserver tracks more than 450 EBS instances exposed online, many in North America and Asia, with unknown numbers still unpatched.
A public proof-of-concept has been released for a critical flaw in libssh2 (CVE-2026-55200), the client-side SSH library embedded in curl, Git, PHP, backup agents, firmware updaters, and countless appliances. A malicious or compromised SSH server can send a crafted packet that corrupts memory on the connecting client, with no credentials or user interaction needed, potentially leading to code execution. Rated 9.2, the bug affects all versions through 1.11.1. The fix was merged into the source on June 12, but no tagged release exists yet, so distributions are backporting it. The hardest part is that libssh2 is often statically bundled, so package updates miss those copies entirely.
Attackers are actively exploiting a critical flaw in PTC Windchill and FlexPLM, product lifecycle management software widely used across automotive, aerospace, defense, and manufacturing to store designs, engineering data, and intellectual property. The bug (CVE-2026-12569) is an unsafe deserialization issue that lets an unauthenticated attacker run code remotely by sending a crafted request. PTC patched it in mid-June, but has since reported heightened activity, with attackers deploying JSP web shells for command execution and data theft. CISA added it to its Known Exploited Vulnerabilities catalog, the first-ever PTC product to be listed, with a federal deadline of June 28. PTC has published indicators of compromise.
Wiz Research found a high-severity flaw in Amazon Q Developer, Amazon's AI coding assistant, that let a malicious code repository run commands and steal a developer's cloud credentials simply by being opened. The bug (CVE-2026-12957) lay in how Amazon Q handled Model Context Protocol servers: it read an MCP configuration file from the open workspace and automatically launched the servers it defined. Because those servers run as local processes that inherit the developer's full environment, a single config file committed to a repo could reach AWS keys, cloud tokens, API secrets, and SSH agent sockets, turning a git clone into a full compromise. Amazon has patched the issue and published an advisory.
