CISA has given US federal civilian agencies a midnight Wednesday May 27 deadline to patch CVE-2026-9082, the highly critical Drupal SQL injection added to its Known Exploited Vulnerabilities catalog on Friday. Imperva says it has now observed 15,000+ attack attempts targeting nearly 6,000 individual Drupal sites across 65 countries since disclosure, with gaming and financial services taking almost half. Shadowserver tracks ~670 unpatched Drupal instances still exposed online (272 in North America, 273 in Europe). CISA's directive is mandatory only for FCEB agencies under BOD 22-01, but the agency strongly urges all organizations to patch immediately.
Qianxin XLab has documented a large-scale ClickFix campaign exploiting CVE-2026-26980, an SQL injection in Ghost CMS that was disclosed and patched on February 19. The vulnerability lets unauthenticated attackers read arbitrary database content including admin API keys, which are then used to inject malicious JavaScript into articles. More than 700 domains are confirmed compromised, including Harvard, Oxford, and Auburn universities and DuckDuckGo. Victim browsers receive a fingerprinted iframe overlay impersonating a Cloudflare prompt that instructs users to paste a command into the Windows command prompt, dropping DLL loaders, JS droppers, or the UtilifySetup.exe Electron-based payload. Two distinct activity clusters compete for compromised sites.
Drupal has issued an update to its highly critical PSA-2026-05-18 advisory confirming that exploit attempts for CVE-2026-9082 are now being detected in the wild. The bug is an SQL injection in Drupal's database abstraction API that lets unauthenticated requests trigger arbitrary SQL on sites running PostgreSQL, with possible escalation to RCE, privilege escalation, and information disclosure. Drupal rates it 23 out of 25 internally though NIST's CVSS v3 score is a mismatched 6.5. CISA added it to KEV on May 22. Affected versions cover Drupal 8.9.x and all 10.x and 11.x branches up to 10.4.10, 10.5.10, 10.6.9, 11.1.10, 11.2.12, and 11.3.10.
LiteSpeed Technologies has patched CVE-2026-48172, a privilege-escalation vulnerability in its cPanel plugin that lets a low-privileged cPanel user trick the plugin into running scripts as root. The flaw has been observed under active exploitation. The fix lands in cPanel plugin v2.4.7 bundled with WHM plugin 5.3.1.0. Operators who cannot patch immediately are advised to uninstall the user-end plugin via /usr/local/lsws/admin/misc/lscmctl cpanelplugin --uninstall. This follows last month's actively exploited CVE-2026-41940 (CVSS 9.8) in cPanel itself, which threat actors used to drop Mirai variants and the Sorry ransomware strain. cPanel hosting providers and resellers are the primary targets.
CISA has added two new entries to its Known Exploited Vulnerabilities catalog. CVE-2025-34291 is an origin-validation/CORS chain in Langflow, a popular open-source AI agent framework, that lets a malicious webpage exfiltrate refresh tokens and reach the code-validation endpoint for full RCE. Active exploitation began on January 23, 2026, and threat actors have been deploying the Flodric botnet through compromised instances. CVE-2026-34926 is a directory-traversal flaw in Trend Micro Apex One (On-Premise) that allows file read or write outside the intended path. FCEB agencies must remediate by June 11 per BOD 22-01; CISA urges all organisations to do the same.
Microsoft has rolled out fixes for two Defender vulnerabilities that have been exploited in zero-day attacks. CVE-2026-41091 is a link-following local privilege escalation in Microsoft Malware Protection Engine 1.1.26030.3008 and earlier that lets attackers gain SYSTEM. CVE-2026-45498 affects Defender Antimalware Platform 4.18.26030.3011 and earlier and triggers denial-of-service. Updates land automatically in Malware Protection Engine 1.1.26040.8 and Antimalware Platform 4.18.26040.7. CISA has added both to its KEV catalog and ordered FCEB agencies to patch within two weeks, by June 3. The same KEV update also added five legacy 2008-2010 Internet Explorer, DirectX, Acrobat, and Windows bugs that CISA suggests are seeing fresh exploitation.
ReliaQuest has documented active in-the-wild exploitation of CVE-2024-12802, a SonicWall Gen6 SSL-VPN MFA bypass that hits Gen6 devices even after they apply the firmware patch. SonicWall's advisory makes clear that on Gen6 hardware, the firmware update alone does not fix it - administrators must also delete the LDAP configuration that uses userPrincipalName, remove cached LDAP users, drop the SSL VPN User Domain back to LocalDomain, reboot, and rebuild the LDAP config without userPrincipalName. Gen7 and Gen8 devices are patched by firmware alone. Intrusions observed between February and March 2026 looked like ransomware initial-access broker activity with 30-60 minute Cobalt Strike and BYOVD attempts.
The 18-year-old heap overflow in NGINX's rewrite module, CVE-2026-42945, disclosed last week as part of the 'Rift' bug cluster, is now seeing real exploitation attempts. AI-native security firm VulnCheck says its honeypot networks have caught attackers probing the flaw, though the goal of the campaigns is not yet clear. The vulnerability lets an unauthenticated attacker crash NGINX worker processes by sending crafted HTTP requests. Turning that crash into remote code execution requires the target host to have Address Space Layout Randomization (ASLR) disabled, which is uncommon by default, but the worker-crash denial-of-service is exploitable on its own and rated urgent.
VulnCheck says attackers are chaining three critical bugs (CVE-2026-28515, CVE-2026-28517, CVE-2026-28516) in openDCIM, an open-source data center management web app, to drop PHP web shells on exposed installs. All three rate CVSS 9.3 and cover missing authorization, OS command injection, and SQL injection. They can be combined over five HTTP requests to land a reverse shell. The activity comes from a single Chinese IP using what VulnCheck describes as a customized version of Vulnhuntr, a public AI-driven vulnerability discovery tool. The campaign is one of the first publicly documented cases of an open-source AI vuln scanner being repurposed for real-world exploitation.
Just two days after a 138-fix Patch Tuesday that listed no zero-days, Microsoft disclosed CVE-2026-42897, an Exchange Server XSS-to-spoofing flaw it has tagged 'Exploitation Detected.' The bug is rated CVSS 8.1 and reported by an anonymous researcher. An unauthenticated attacker emails a crafted message; if the victim opens it in Outlook Web Access and meets certain interaction conditions, arbitrary JavaScript runs in the browser session context, enabling spoofing and session abuse. On-prem Exchange Server 2016, 2019, and Subscription Edition are affected; Exchange Online is not. No permanent patch exists yet, only mitigation through the Exchange Emergency Mitigation Service.
