Recommendations

  1. Review and patch all Critical and High severity CVEs immediately
  2. Prioritize the 4 KEV-listed CVEs -confirmed active exploitation
  3. Implement compensating controls for the 230 unpatched Critical/High CVEs
  4. Assess exposure to the 75 CVEs with public exploit code
  5. Monitor vendor advisories for updates and additional patches

Top 10 Priority CVEs

126
CVE-2026-41091 HIGH KEV POC

Local privilege escalation in Microsoft Defender (Malware Protection Engine) enables an authenticated low-privileged attacker to elevate to SYSTEM by abusing improper link resolution (CWE-59) before file access. The flaw scores CVSS 7.8 with high impact to confidentiality, integrity, and availability, and no public exploit is identified at time of analysis. Microsoft has released a patch via MSRC, and there is no current CISA KEV listing or EPSS signal indicating active mass exploitation.

108
CVE-2026-9082 MEDIUM KEV POC

SQL injection in Drupal Core across six major version branches (8.9.0 through 11.3.x) enables remote unauthenticated attackers to manipulate database queries with no required privileges or user interaction, as confirmed by CVSS vector AV:N/AC:L/PR:N/UI:N. The vulnerability yields partial confidentiality and integrity impact per CVSS - enabling data enumeration and limited data manipulation - but does not grant full database control or server compromise. No active exploitation is confirmed (not listed in CISA KEV; SSVC exploitation status: none), but SSVC flags this as automatable, making opportunistic mass scanning against the large global Drupal install base a credible near-term risk.

92
CVE-2026-45498 MEDIUM KEV POC

Denial of service in Microsoft Defender Antimalware Platform allows a local, unprivileged attacker to partially degrade availability with low attack complexity and no user interaction required. The CVSS 4.0 score reflects limited impact - confidentiality and integrity are unaffected, and availability impact is rated Low. Vendor patch is available via Microsoft Security Response Center; no public exploit identified at time of analysis and no CISA KEV listing.

89
CVE-2026-34926 MEDIUM KEV

Directory traversal in Trend Micro Apex One on-premise server (versions before 14.0.0.17079) enables a highly privileged local attacker to manipulate a key server table and inject malicious code that propagates to all managed endpoint agents, effectively weaponizing the EDR platform's own distribution infrastructure. The attack requires an adversary who has already obtained administrative credentials to the Apex One server through a separate compromise vector. No public exploit code has been identified at time of analysis and the vulnerability is not listed in CISA KEV, but the changed scope (S:C) in the CVSS vector signals that a successful exploit extends impact beyond the server itself to the entire managed agent fleet.

69
CVE-2026-31072 CRITICAL POC

Remote code execution in APScheduler (all versions through 3.10.x and 4.0.0a5) is achievable when applications deserialize attacker-controlled data via the bundled JSONSerializer or CBORSerializer. The unmarshal_object routine dynamically imports modules and invokes __setstate__ on arbitrary classes, letting an attacker pivot an untrusted payload into code execution; publicly available exploit code exists, though EPSS remains low at 0.06% (19th percentile).

67
CVE-2026-41948 CRITICAL POC

Path traversal in Dify versions 0 through 1.14.1 allows authenticated tenants to escape their authorized tenant path and reach the Plugin Daemon's internal REST API, including debug interfaces, by smuggling unencoded dot sequences through task identifiers or filename parameters. Because Dify Cloud permits unauthenticated free self-registration, the authentication barrier collapses to trivial account creation, and publicly available exploit code exists; the attacker only needs the victim tenant's UUID to pivot. CVSS 4.0 is rated 9.2 with high confidentiality and integrity impact.

66
CVE-2026-31071 CRITICAL POC

Unauthenticated API access in LalanaChami Pharmacy Management System (commit 5c3d028) allows remote attackers to dump all user records including bcrypt password hashes, tamper with drug inventory, and read private medical prescription data. The flaw stems from missing authentication middleware on backend Express routes such as /api/user/getUserData and /api/doctorOder. Publicly available exploit code exists, though EPSS rates exploitation probability at only 0.06% (17th percentile), consistent with a low-deployment open-source project rather than mass exploitation.

67
CVE-2026-41947 CRITICAL POC

Cross-tenant authorization bypass in LangGenius Dify versions through 1.14.1 lets any logged-in editor reroute another tenant's LLM trace traffic - including prompts and model responses - to an attacker-controlled observability provider. Because Dify Cloud permits free self-registration, the authentication barrier is effectively trivial; publicly available exploit code exists and a vendor patch is shipped via PR #35793. The flaw is an instance of CWE-639 (insecure direct object reference) in the trace-configuration endpoints, which accepted an app_id without validating tenant ownership.

64
CVE-2026-3220 HIGH POC

The Autoptimize WordPress plugin before 3.1.15, Clearfy Cache WordPress plugin before 2.4.2, Speed Optimizer WordPress plugin before 7.7.9 are vulnerable to unauthenticated Stored Cross-Site Scripting (XSS) due to a predictable replacement hash used during the HTML minification process and abusing a regular expression. This allows an attacker to inject arbitrary HTML attributes in the final HTML output by anticipating the placeholder format.

57
CVE-2026-9348 HIGH POC

Stack-based buffer overflow in Edimax EW-7438RPn WiFi range extender firmware up to version 1.31 enables authenticated remote attackers to execute arbitrary code by sending malicious input to the /goform/mp endpoint in the web server component. Public exploit code exists on GitHub, though the vulnerability is not listed in CISA KEV. The vendor failed to respond to responsible disclosure attempts, leaving devices unpatched.
