🔒 The U.S. Cybersecurity and Infrastructure Security Agency (CISA) warns that attackers are actively exploiting arbitrary file upload vulnerabilities in the iCagenda and Balbooa Forms Joomla extensions to achieve remote code execution. The agency designated these flaws as maximum priority and ordered federal agencies to apply updates or mitigations within three days. Vendors released fixes in iCagenda 4.0.8/3.9.15 and Balbooa Forms 2.4.1 after automated and zero-day exploitation was observed. Administrators should check installations and apply the available patches immediately.

🛡️ The Australian Cyber Security Centre (ACSC) has warned of a large-scale campaign scanning and exploiting vulnerabilities in content management systems worldwide, impacting many SMBs in Australia. The actors deploy webshells via flaws allowing unauthenticated file upload, remote code execution, SSRF or deserialization, affecting products like WordPress, Joomla, Craft CMS and others. The ACSC advises inspecting servers for compromise, isolating and remediating infected hosts, patching vulnerable systems, and restoring from known-good backups.

🔒 Researchers at Binarly disclosed six vulnerabilities in U-Boot, the bootloader used across routers, cameras, and server management controllers. Two flaws allow code execution during image parsing before signature verification, while four cause crashes. The bugs trace to unchecked returns from fdt_get_name and other parsing errors; patches were merged but not yet broadly distributed.

🔒 Three critical vulnerabilities in the OpenClaw personal AI assistant could allow credential theft, privilege escalation, and arbitrary host code execution if exploited. The flaws include two command injection bugs (GHSA-hjr6-g723-hmfm and GHSA-9969-8g9h-rxwm) and a path traversal/link-following issue (GHSA-575v-8hfq-m3mc). OpenClaw 2026.6.6 patches these issues; operators are advised to harden configurations and limit tool/channel allowlists.

🔒 A new AI Now Institute report demonstrates a proof-of-concept exploit that coerces Anthropic’s Claude Code and OpenAI’s Codex into executing attacker-supplied binaries during automated code review. The attack uses multi-stage prompt injection hidden in repository files (documentation, comments) to trick agents in auto-mode or auto-review into running a seemingly benign script that launches a malicious payload. Researchers warn the architectural risk — agents’ inability to reliably attribute text sources — makes such platforms potential attack vectors when granted shell access and autonomous execution.

🔒 Ubiquiti has released updates to remediate several critical vulnerabilities across UniFi Connect, UniFi Talk, UniFi Access, UniFi Protect, and UniFi OS. The flaws include command injection, authenticated SQL injection, SSRF, and improper access control, with multiple CVSS scores at or near 10.0. Affected versions are identified for each product and updated builds are available that address the issues.

🔒 The U.S. Cybersecurity and Infrastructure Security Agency has ordered federal agencies to patch an actively exploited, maximum-severity vulnerability in Adobe ColdFusion (CVE-2026-48282) by Friday. Adobe published fixes for affected ColdFusion versions last week and urged administrators to install updates immediately. The flaw enables unauthenticated remote code execution in low-complexity attacks and has been observed in the wild soon after disclosure. CISA added the issue to its KEV catalog and invoked BOD 26-04 to enforce remediation timelines for FCEB agencies.

🛡️ A critical flaw in Google Dialogflow CX's Code Blocks could let an attacker with edit rights on one agent compromise other Code Block-enabled agents in the same Google Cloud project. Varonis named the issue Rogue Agent; it required the dialogflow.playbooks.update permission and thus implied a malicious insider or compromised developer account rather than an unauthenticated internet attacker. Google fixed the vulnerability after Varonis disclosed it via the VRP; there are no signs of exploitation.

🔧 Adobe has issued emergency updates to fix a maximum-severity ColdFusion vulnerability (CVE-2026-48282) that is now being actively exploited, the Canadian Center for Cyber Security (CCCS) warned. The flaw affects ColdFusion 2025.9, 2023.20, and earlier, enabling unauthenticated remote code execution on unpatched systems. Adobe urges administrators to install the patch immediately, and Shadowserver reports nearly 800 exposed ColdFusion instances online.

🔒 Security firm runZero disclosed seven vulnerabilities in the FatFs filesystem library used to read FAT/exFAT on many embedded devices. The bugs—rated Medium to High—can lead to memory corruption, crashes, data leaks, or code execution when a device mounts malformed media or firmware images. Only the GPT hang issue is fixed upstream; most fixes must come from downstream vendors who bundle FatFs. runZero published PoCs and urges vendors and integrators to audit wrappers and treat physical ports and update channels as attack surfaces.

🔒 A critical vulnerability in Argo CD repo-server exposes risks inherent to GitOps platforms. Synacktiv found the unauthenticated GenerateManifest gRPC endpoint can be abused via Kustomize/Helm options to execute commands if an attacker can reach both the repo-server and Redis ports. The issue affects typical Helm deployments where Kubernetes network policies are not enabled by default, enabling lateral movement from a compromised pod. Synacktiv disclosed details July 1, 2026 and recommends strict network segmentation until a patch is available.

🔒 CISA has added a high-severity SharePoint Server vulnerability, CVE-2026-45659 (CVSS 8.8), to its Known Exploited Vulnerabilities catalog following evidence of active exploitation. Microsoft patched the deserialization-based remote code execution flaw in May 2026 for SharePoint Server Subscription Edition, SharePoint Server 2019, and SharePoint Enterprise Server 2016. The issue can be triggered by any authenticated attacker with as little as Site Member permissions and does not require elevated privileges. Federal agencies are advised to apply updates by July 4, 2026, while Microsoft assesses public exploitation as "Exploitation Less Likely."

🛡️ Researchers discovered two vulnerabilities in the Cursor AI-enabled IDE that enable prompt-injection-driven remote code execution by escaping the command execution sandbox. The flaws, CVE-2026-50548 and CVE-2026-50549, allow attackers to change the working directory and exploit symlink canonicalization fallbacks to write or overwrite files outside the project scope. Cursor patched the issues in version 3.0, and the findings underscore broader risks in agentic AI workflows and the difficulty of defending against prompt injection.

🔒 Synacktiv disclosed an unpatched vulnerability in Argo CD's repo-server that allows unauthenticated attackers to execute arbitrary commands if they can reach the component's internal gRPC port. The flaw abuses kustomize's --helm-command option to run attacker-controlled scripts, demonstrated against Argo CD v2.13.3, and can lead to full cluster takeover by leveraging exposed Redis credentials. There is no fixed release or CVE; operators must enable Kubernetes network policies to isolate repo-server and Redis until a patch is available.
