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.
Google has accidentally published the technical details of an unfixed Chromium vulnerability that lets a malicious webpage run JavaScript on a visitor's device even after the browser is closed. The issue, originally reported by researcher Lyra Rebane in December 2022, abuses a Service Worker download task that never terminates. It was marked 'fixed' on February 12 and the bug tracker went public on May 20 after the 14-week visibility timer expired, but Rebane re-tested the latest Chrome Dev 150 and Edge 148 and confirmed the bug still works. Microsoft Edge no longer shows a download prompt, making the persistence completely silent. All Chromium-based browsers are affected.
Cisco has patched a maximum-severity flaw, CVE-2026-20223, in the internal REST APIs of Cisco Secure Workload (formerly Tetration), the zero-trust microsegmentation platform used to stop lateral movement in enterprise environments. Insufficient authentication on the affected endpoints lets an unauthenticated remote attacker craft a request that returns sensitive data and modifies configuration with Site Admin privileges across tenant boundaries. Cisco's PSIRT says there is no evidence of in-the-wild exploitation yet and no workaround exists. The on-prem fixed releases are 3.10.8.3 and 4.0.3.17; the SaaS deployment has already been patched. Sites running 3.9 or earlier must migrate to a fixed release.
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.
Aikido Security's Joe Leon has documented that standard Google Cloud API keys keep working for up to 23 minutes after they are deleted from the GCP console, with a median revocation window of 16 minutes. Over 10 trials across two days, the team kept sending authenticated requests at 3-5 per second; one trial saw 79% of requests succeed one minute after deletion. During this window, an attacker holding a leaked key retains full access to any enabled API on the project, including Gemini file dumps, BigQuery, and Maps. Google closed the bug report as 'won't fix.' Service-account deletions propagate in around 5 seconds; only standard API keys are slow.
Universal Robots, the Danish maker of the PolyScope 5 collaborative-robot controllers used across manufacturing, logistics, automotive, and healthcare, has patched CVE-2026-8153, a CVSS 9.8 OS command injection in the Dashboard Server interface. The server accepts user-controlled input and passes it to the underlying Linux OS without proper neutralization, so anyone with network access to the Dashboard Server port can achieve unauthenticated remote code execution on the robot controller - effectively a Linux machine wired directly into physical machinery. Vera Mens of Claroty Team82 discovered and reported the flaw through CISA and CERT/CC's VINCE coordination. Exploitation requires the Dashboard Server to be enabled in the UI.
Ubiquiti has shipped patches for five UniFi OS vulnerabilities, three of which are CVSS-maximum and exploitable by remote unauthenticated attackers. CVE-2026-34908 is an improper access control that lets attackers make unauthorized changes; CVE-2026-34909 is a path traversal that reaches an underlying system account; CVE-2026-34910 is an unauthenticated command injection. Two additional flaws (CVE-2026-33000, a critical command injection, and CVE-2026-34911, a high-severity info disclosure) were also patched. All five came through Ubiquiti's HackerOne program. Censys is tracking close to 100,000 internet-exposed UniFi OS endpoints, around 50,000 of them in the US. Ubiquiti products were previously hijacked into the GRU-operated Moobot botnet.
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.
Qualys has disclosed a 9-year-old privilege management flaw in the Linux kernel that lets an unprivileged local user disclose /etc/shadow and host SSH private keys, then chain four different post-disclosure exploits (chage, ssh-keysign, pkexec, and accounts-daemon) to execute commands as root. The bug is tracked as CVE-2026-46333 and was introduced in November 2016 in the kernel's __ptrace_may_access() function. It affects default installs of Debian, Fedora, and Ubuntu. A proof-of-concept has been released and a public kernel commit landed. Qualys recommends rotating SSH host keys on any host that allowed untrusted local users before patching.
