Jenkins Patches 20 Plugin Flaws Leading to RCE, XSS and Credential Theft

Jenkins patched 20 vulnerabilities across 13 plugins, including Groovy sandbox bypasses enabling remote code execution on CI/CD controllers.

Jenkins released security updates on September 16, 2026 for 20 vulnerabilities across 13 plugins, including nine fixes in the Script Security Plugin for Groovy sandbox bypasses. CVE-2026-92127 (classpath abuse) and CVE-2026-92128 (TOCTOU race on remote JAR loading) could allow arbitrary code execution in the controller JVM, exposing build secrets, credentials, and downstream deployment environments. Other flaws include stored XSS in the Warnings, Coverage, OWASP Dependency-Check and Gitee plugins, SSRF in the Gradle and Bitbucket plugins enabling credential capture, credential exposure via CVE-2026-92130, arbitrary file write via CVE-2026-92137, OAuth token theft, and an open redirect in the Keycloak Authentication Plugin. No exploitation is reported; fixes include Script Security Plugin 1422.v06869826dd9b_.

Unauthenticated RCE Flaws Could Expose 200,000+ WordPress Sites to Takeover

Two unauthenticated CVSS 9.8 code-injection and PHP object injection flaws in The Events Calendar plugin expose 200,000+ WordPress sites to RCE and takeover.

Defiant identified two critical vulnerabilities in The Events Calendar WordPress plugin, which has over 600,000 active installations. CVE-2026-78159, unauthenticated code injection during single-event HTML processing, was patched in version 6.17.3.1 on August 25; CVE-2026-78006, unauthenticated PHP object injection via event comments, was patched in 6.17.4.1 on September 10. Both independent chains lead to remote code execution and full site compromise. Roughly 240,000 sites run versions vulnerable to both flaws, and about 300,000 downloads between September 10 and 14 suggest half of installations may still lack the second fix.

Acronis Patches Exploited Vulnerability in cPanel Backup Plugin

Acronis urgently patched CVE-2026-87886 (CVSS 7.8), insecure file permissions enabling privilege escalation, exploited in targeted attacks on cPanel & WHM backups.

Acronis released urgent patches for CVE-2026-87886 (CVSS 7.8), insecure file permissions in the Backup plugin for cPanel & WHM and the Backup extension for Plesk that allow attackers to gain elevated privileges. Exploitation has been detected in the wild in limited, targeted attacks against the cPanel & WHM plugin, but not against the Plesk extension. All Linux versions of the plugin before build 1.9.3.1021 and the Plesk extension before build 1.8.11.638 are affected; Acronis urges immediate updates and has not shared technical details.

BambooToken: The Malware That Speaks MQTT to Stay Under the Radar

Lumen's Black Lotus Labs uncovered BambooToken, a Windows and Linux malware family using MQTT broker-based C2 and DLL sideloading across Asia since February 2023.

Lumen Black Lotus Labs identified BambooToken, a multiplatform malware family that exchanges commands through MQTT brokers so infected hosts never contact the C2 server directly, active from at least February 2023 through July 2026. The Windows variant sideloads via Tendyron's OnKey hardware-token software used in Chinese banking and government, or impersonates Kingsoft Office, without either vendor's signing certificate being compromised; a Linux build appeared by December 2025 with shell, file transfer, and system information commands. Victims include MikroTik and DrayTek routers in Singapore, Cambodia, and Vietnam reached after internet-wide SNMP scanning, and Lumen cannot attribute the family to any known actor.

Active Exploitation Triggers Emergency Patch for Cisco ISE Zero-Day

Cisco urgently patched actively exploited zero-day CVE-2026-76460 (CVSS 10.0), an ISE authentication bypass enabling root command execution; CISA added it to KEV.

Cisco released emergency patches for CVE-2026-76460 (CVSS 10.0), a zero-day authentication bypass in an API endpoint of Identity Services Engine (ISE) and ISE Passive Identity Connector (ISE-PIC), and confirmed active exploitation in the wild. Successful exploitation lets attackers bypass the web-based management interface and execute commands with root privileges, allowing them to hide or delete indicators of compromise. Fixed releases are ISE/ISE-PIC 3.5 Patch 4, 3.4 Patch 7, 3.3 Patch 12, 3.2 Patch 11, and 3.1 Patch 12; no workarounds exist beyond restricting traffic with infrastructure ACLs. CISA added the flaw to its Known Exploited Vulnerabilities catalog, giving US federal agencies three days to patch under BOD 26-04.

CVE-2026-91752: GNU libextractor < 1.15 Stack Overflow via OLE2

GNU libextractor before 1.15 has a stack-based buffer overflow (CVE-2026-91752) in its OLE2 parser, triggerable via crafted files.

A stack-based buffer overflow was identified in GNU libextractor's OLE2 plugin in versions prior to 1.15, assigned CVE-2026-91752. The flaw resides in the process_star_office function, which sizes a variable-length stack array using attacker-controlled OLE2 stream data. Attackers can craft malicious OLE2/StarOffice files to trigger the overflow. The issue was disclosed on the oss-security mailing list by researcher Haitam Lazaar on September 16, 2026.

When scanners miss the attack: how Cloudflare Client-Side Security protects storefronts

Cloudflare's Page Shield ML uncovered four malicious JavaScript campaigns on storefronts, including affiliate fraud and a remote-backdoor script, that VirusTotal and URLScan missed.

Cloudflare's Page Shield ML detected four client-side JavaScript operations (eight payloads) in live traffic on online storefronts, enabling affiliate commission hijacking, clickless affiliate theft via hidden iframes, user tracking with a remote-code backdoor, and cloaking of paid mobile visitors. Seven of the eight payloads were absent from VirusTotal and URLScan returned no malicious verdict for any, including a Lnkr-family payload indexed unclassified for roughly 2.5 years. Detection relies on a graph neural network over JavaScript syntax trees, an LLM second opinion on Workers AI, and a frontier-model ensemble voting across benign, magecart, other malware, and cryptomining labels.

Hackers Use Cross-Platform Noodle RAT to Secretly Control Windows and Linux Systems

Check Point identifies Noodle RAT as a distinct cross-platform Windows/Linux backdoor used by Chinese-speaking actors against Asia-Pacific organizations since 2016.

Check Point assesses Noodle RAT, also known as ANGRYREBEL, as a distinct backdoor family rather than a variant of Gh0st RAT or Rekoobe, with separate Windows (Win.NOODLERAT) and Linux (Linux.NOODLERAT) variants sharing a common command-and-control design. The Windows implant runs filelessly via shellcode with loaders like MULTIDROP and MICROLOAD, while the Linux variant provides reverse shells, file management, and SOCKS tunneling after exploitation or web-shell placement on exposed servers. Groups including Iron Tiger, Calypso APT, Rocke, and Cloud Snooper have deployed it against organizations in Thailand, India, Japan, Malaysia, and Taiwan. Check Point released sample hashes and C2 IP indicators alongside the analysis.

Smishing Hackers Can Watch Every Keystroke as Victims Enter Card Details and OTPs

Group-IB details the JWR smishing kit, used by the Outsider cluster, that streams keystrokes and OTPs to fraudsters in real time via WebSocket.

Group-IB linked the JWR phishing kit to an operator cluster it tracks as Outsider within the broader Smishing Triad ecosystem. Fake toll, parcel, and delivery messages lead to live phishing pages that capture card numbers, passwords, and one-time passcodes before victims submit forms. The kit supports up to 32 guided pages, AES-256-CTR wrapped traffic with keys embedded per message, rotating short links and domains, and WordPress or Shopify integration markers, enabling account takeover and unauthorized payments.

Cyberthreats are moving faster than SMBs: Readiness must acceleratenew

ESET's SMB Cyber Readiness Index 2026 finds 73% of SMBs adopting AI while 40% lack AI policy, and reports 3,000+ malicious AI agent skills.

ESET argues AI is accelerating cyberthreats while expanding the attack surface: its SMB Cyber Readiness Index 2026 found 73% of SMBs integrating AI and 40% of businesses lacking a proper AI policy. ESET analyzed 900,000 AI agent skills across popular repositories between March and May 2026, finding over 25,000 suspicious and more than 3,000 malicious skills that exfiltrate data, execute malware, or abuse prompt injection. The piece also cites AI-assisted reconnaissance, exploit development, and social engineering, plus PromptSpy, an Android spyware abusing Google Gemini at runtime for persistence.
