CISA adds two actively exploited Joomla extension flaws to the KEV catalog

CISA · July 10, 2026

CISA added CVE-2026-48939 (iCagenda) and CVE-2026-56291 (Balbooa Forms) to the Known Exploited Vulnerabilities catalog based on evidence of active exploitation. Both are unrestricted upload of file with dangerous type vulnerabilities in popular Joomla extensions — a bug class that typically leads to webshell deployment and full site takeover. CISA did not publish CVSS scores in the alert; under BOD 26-04, federal civilian agencies must prioritize rapid remediation of KEV-listed flaws on publicly exposed assets.

“These types of vulnerabilities are a frequent attack vector for malicious cyber actors and pose significant risks to the federal enterprise.” — CISA

Progress tells ShareFile customers to shut down Storage Zone Controllers over “credible external security threat”

Progress Software · July 10, 2026

Progress Software ordered every organization running an on-premises ShareFile Storage Zone Controller to immediately shut down the Windows server hosting it, citing a “credible external security threat.” There is no patch to apply instead; Progress has also temporarily disabled access to affected accounts and listed Storage Zone Controller customers as “not operational” on its status page. The company says it has no indication of unauthorized access to any ShareFile accounts or data, but has not disclosed the nature of the threat or a restart timeline. Cloud-only ShareFile accounts are not affected. The same component was exploited in the wild in 2023 (CVE-2023-24489) while the product belonged to Citrix.

Coinspect discloses “Ill Bloom” weak-randomness wallet flaw; more than $5M already drained

Coinspect · July 10, 2026

Security firm Coinspect disclosed Ill Bloom, a weak-randomness flaw in the recovery-phrase generation of certain software wallets — mostly older or lesser-known mobile apps, some dating to 2018 — that lets attackers derive private keys and is being actively exploited. Coinspect confirmed a coordinated sweep on May 27 that drained about $3.1 million from 431 wallets, with total outflows from exposed wallets now past $5 million across Bitcoin, Ethereum, Rootstock, Tron, and Polygon. Hardware wallets and most mainstream software wallets are not affected; Coinspect published a free address checker at illbloom.org and warns that matched wallets should be treated as compromised.

“If funds recently moved without your permission, this vulnerability may be why.” — Coinspect

PraisonAI RCE via unsandboxed LLM-generated code scores a perfect CVSS 10.0

CVE Program (VulnCheck) · July 11, 2026

CVE-2026-61447 (CVSS 4.0: 10.0) is a critical remote code execution flaw in the PraisonAI agent framework before version 1.6.78. The CodeAgent._execute_python() method runs Python code generated by the LLM with no AST validation, import restrictions, or sandboxing, so an unauthenticated attacker who can submit prompts can steer the model into producing arbitrary code that executes on the host and exfiltrates environment secrets. No in-the-wild exploitation has been confirmed and the fix is to upgrade to 1.6.78 or later. It is not in the KEV catalog.

PraisonAI “executes LLM-generated Python code without AST validation, import restrictions, or sandbox enforcement.” — CVE-2026-61447 record

Microsoft Defender “RoguePlanet” patched, then researcher reports new Defender bugs
Microsoft MSRC · July 9, 2026 (updated July 11)
Microsoft remediated CVE-2026-50656 (CVSS 7.8), the RoguePlanet privilege-escalation race condition in the Malware Protection Engine that could spawn a SYSTEM shell, in engine version 1.1.26060.3008 — no customer action required. The researcher who disclosed it (Chaotic Eclipse) has since reported that the accompanying hardening can leak 8 bytes of data and that Defender’s caching of oversized Zone.Identifier streams can be abused via a malicious SMB server to exhaust disk space on Windows 11 25H2 and Server 2025; Microsoft told The Hacker News it is “aware of this report and are investigating.”

North Korean “PolinRider” campaign publishes 108 malicious packages and extensions across npm, Packagist, Go, and Chrome

Socket / The Hacker News · July 4, 2026

Threat actors tied to North Korea’s Contagious Interview operation have published 162 malicious release artifacts corresponding to 108 unique packages and extensions — 19 npm libraries, 10 Composer packages, 61 Go modules, and one Google Chrome extension. The campaign, tracked as PolinRider, plants obfuscated JavaScript loaders in legitimate repositories (concealed via whitespace padding or fake .woff2 font files) and triggers execution through VS Code task files with the “runOn: ‘folderOpen'” option; payloads fetch encrypted second stages from blockchain infrastructure that unpack to the DEV#POPPER RAT and OmniStealer. As of April 11, 2026, the broader activity had compromised 1,951 public GitHub repositories belonging to 1,047 unique owners. There is no CVE — this is an account-takeover and supply-chain campaign, and it remains active.

“The campaign remains active, and new malicious packages are likely to continue appearing as threat actors compromise maintainer accounts, modify legitimate repositories, and publish infected package versions where they retain or obtain registry access.” — Karlo Zanki, Socket

JadePuffer: first documented ransomware operation run end-to-end by an AI agent

Sysdig · July 4, 2026

Sysdig researchers documented what they believe is the first ransomware intrusion conducted entirely by an autonomous LLM agent — reconnaissance, credential theft, lateral movement, persistence, privilege escalation, and encryption, with the agent adapting to failures in real time. Initial access came via CVE-2025-3248, a critical unauthenticated remote code execution flaw in the Langflow LLM-app framework that was patched in April 2025 and added to CISA’s KEV catalog in May 2025; the attacker later pivoted to an Alibaba Nacos instance using CVE-2021-29441, an authentication bypass. The operation encrypted 1,342 Nacos service configuration items, dropped the originals, and left a ransom demand with a Bitcoin address and Proton Mail contact — though the encryption key was never stored or transmitted, and the Bitcoin address appears to be a documentation example reproduced from training data.

“The operation also adapted in real time, retrying failed steps within refined parameters. In one sequence, it went from a failed login to a working fix in 31 seconds.” — Sysdig

U.S. government entity paid Kairos ~$1 million in encryption-free data extortion, blockchain analysis shows

Ransom-ISAC · July 4, 2026

A case study by Rakesh Krishnan for Ransom-ISAC, built on a leaked negotiation chat and on-chain tracing, shows a small U.S. government entity — the evidence points to Union County, Ohio, though neither party has confirmed it — paid roughly 9.44 BTC (~$1 million) on June 13, 2025 to keep stolen files from being published. The Kairos group deployed no encryptor at all: it opened at $3 million claiming over 2 TB of stolen data, and used countdown timers and threats to leak a “prosecutors office” folder first. The payment was traced through wallet chains toward deposit addresses at Bybit, OKX, and the Russian service BELQI. The case underscores a broader shift: much of what is still called ransomware now skips encryption entirely and uses stolen data as the sole pressure point.

“Paying to make stolen data disappear is an act of faith, and the receipt is written by the thief.” — The Hacker News

Opera GX flaw let malicious sites silently install browser mods and steal data from visited pages

The Hacker News · July 6, 2026

Researchers disclosed a vulnerability in Opera GX that allowed a malicious website to silently install a GX Mod — the browser’s reskinning add-on format — and use it to lift data from pages the victim visits; a proof of concept reconstructed a signed-in user’s full Gmail address from a single visit with no clicks. Opera patched the flaw in Opera GX 130.0.5847.89 and says it found no evidence of in-the-wild exploitation. No CVE was assigned, but Opera’s bug bounty team rated the issue P1 (its top severity) and paid the maximum $5,000 reward. Because the attack required no clicks or approvals, there was no workaround short of the patch — users should confirm their version at opera://about.

SkillCloak: malicious AI agent “skills” evade static scanners more than 90% of the time

The Hacker News · July 6, 2026

Researchers at the Hong Kong University of Science and Technology showed that scanners meant to catch malicious add-on skills for AI coding agents (Claude Code, OpenAI Codex, OpenClaw) can be defeated with simple self-extracting packing techniques that leave the malware fully functional — their strongest variant slipped past every scanner tested more than 90% of the time. Skills run with the agent’s own access to files, terminals, and saved credentials, and most marketplace listings are uploaded by strangers with little vetting. The team also built a runtime checker that catches most of the disguised skills static scanners miss.

“Bad Epoll” Linux kernel flaw (CVE-2026-46242) — The Hacker News · July 3, 2026. A use-after-free race in the kernel’s epoll code lets an unprivileged local user gain root with roughly 99% exploit reliability, affecting desktops, servers, and Android on kernels v6.4 and newer. Researcher Jaeyoung Chung published a working proof of concept; the fix landed upstream (commit a6dc643c6931) in April 2026, but distributions that have not backported it remain exposed, and epoll cannot be disabled as a workaround.
