CVE-2026-42889 May 12, 19:30 CRITICAL PATCH Act Now

Authentication bypass in Relay Server 0.9.0-0.9.6 (the real-time collaboration backend for the Obsidian Relay plugin) lets unauthenticated network attackers read and modify synced documents. When authentication is enabled, the multi-document WebSocket endpoints incorrectly treated connections lacking a token query parameter as fully privileged, so anyone who knows or guesses a document ID can join the sync session without a valid document token. Publicly available exploit code exists per SSVC (POC), but EPSS is very low (0.04%) and it is not listed in CISA KEV, so there is no confirmed active exploitation.

Authentication-layer injection in OX Dovecot Pro (versions up to and including 2.4.3 and 3.1.4) arises from a flaw in the 'safe' template filter: when 'safe' is applied during variable expansion, every subsequent pipeline stage on the same string inherits the 'safe' designation, so attacker-controlled data that should be escaped is passed through unescaped. Because variable expansion is used to build authentication backend queries, this enables SQL or LDAP injection by remote unauthenticated attackers. There is no public exploit identified at time of analysis, and EPSS exploitation probability is negligible (0.01%, 2nd percentile).

Local privilege escalation in Microsoft Office Click-To-Run (Microsoft 365 Apps, Office 2019, Office LTSC 2021/2024) allows an authenticated local attacker to elevate privileges due to improper access control in the update/servicing component. A successful attack results in total compromise of confidentiality, integrity, and availability with a scope change beyond the vulnerable component. There is no public exploit identified at time of analysis and EPSS exploitation probability is very low (0.04%, 12th percentile), but the vendor rates technical impact as total.

CVE-2026-35436 May 12, 16:59 HIGH PATCH Exploit Unlikely This Week

Local privilege escalation in Microsoft Office Click-To-Run (the servicing/update engine behind Microsoft 365 Apps, Office 2019, and Office LTSC 2021/2024) lets an already-authenticated low-privileged user escalate to higher privileges on the host due to insufficiently granular access control (CWE-1220). The CVSS 3.1 vector (AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H) shows a scope change with total confidentiality, integrity, and availability impact, meaning a successful attacker crosses a security boundary from the Office servicing context to the wider system. There is no public exploit identified at time of analysis, EPSS is very low (0.04%), and CISA SSVC rates exploitation as 'none', so this is a serious-but-not-actively-exploited local EoP that should be patched on the normal accelerated cycle.

CVE-2026-40398 May 12, 16:59 HIGH PATCH Exploit Likely This Week

Local privilege escalation in the Windows Remote Desktop component (CWE-122 heap-based buffer overflow) allows an authenticated low-privileged user to gain SYSTEM-level control across virtually all supported Windows client and server releases, from Windows 10 1607 through Windows 11 26H1 and Windows Server 2012 through 2025. Microsoft has released patches; there is no public exploit identified at time of analysis and EPSS exploitation probability is very low (0.04%), consistent with CISA SSVC rating exploitation as 'none'. The flaw is a serious defense-in-depth concern because it grants total confidentiality, integrity, and availability impact once a foothold exists, but it is not remotely reachable and requires prior local access.

Authenticated code execution on Nomad client hosts is possible in HashiCorp Nomad and Nomad Enterprise 1.10.0 through versions prior to 2.0.1 via a path traversal flaw in the dynamic host volume feature. A submitter with volume-creation privileges can escape the intended volume directory and write to or execute code in arbitrary locations on the client node's filesystem, gaining code execution outside the intended sandbox. This flaw is not in CISA KEV and has no public exploit identified at time of analysis; EPSS probability is low at 0.03%.

Local privilege escalation in the Windows Kernel affects Windows 11 (24H2, 25H2, 26H1) and Windows Server 2025, where an untrusted pointer dereference (CWE-822) lets an already-authenticated local attacker execute code with SYSTEM-level privileges. Microsoft has released a patch, and no public exploit is identified at time of analysis; EPSS exploitation probability is very low (0.03%) and the flaw is not on CISA KEV. Despite the 'Information Disclosure' tag applied in vendor metadata, the CVSS vector and description describe a privilege-elevation primitive with total confidentiality, integrity, and availability impact on the affected host.

CVE-2025-53844 May 12, 16:54 HIGH This Week

Remote code execution in Fortinet FortiOS 7.2.0-7.2.11, 7.4.0-7.4.8, and 7.6.0-7.6.3 enables authenticated attackers to execute arbitrary code via malformed network packets. The out-of-bounds write vulnerability (CWE-787) affects FortiOS firewall appliances and requires only low-privilege credentials to exploit over the network. Fortinet published advisory FG-IR-26-123 confirming the vulnerability. No CISA KEV listing or public exploit code identified at time of analysis, though the straightforward network attack vector (AV:N/AC:L) suggests moderate weaponization potential once details emerge.

Memory corruption in Mozilla Firefox versions prior to 150.0.3 stems from a JIT (Just-In-Time) compiler miscompilation in the JavaScript engine, allowing remote attackers to trigger high-impact compromise of confidentiality, integrity, and availability when a user visits a malicious web page. The flaw carries a CVSS score of 8.8 and requires user interaction (loading attacker-controlled JavaScript), but no authentication. There is no public exploit identified at time of analysis, though a GitHub repository referenced from NVD suggests early proof-of-concept research, and EPSS scores the exploitation probability at only 0.02% despite the high CVSS severity.

CVE-2026-42289 May 12, 22:23 HIGH This Week

Cross-site request forgery in ChurchCRM's UserEditor.php (versions prior to 7.3.2) lets an unauthenticated attacker forge account-management requests that execute with an authenticated administrator's session. Because the endpoint processes user creation and permission changes from $_POST parameters with no CSRF token, a victim admin who visits a malicious page can be tricked into silently promoting a low-privilege user to administrator or minting a new admin backdoor account. Publicly available exploit code exists (SSVC: poc) but the flaw is not in CISA KEV, and EPSS is very low (0.02%, 4th percentile), indicating no evidence of widespread exploitation.
