Budding infosec pros and aspiring cyber crooks targeted with fake PoC exploits

The OwnID Passwordless Login plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 1.3.4. This is due to the plugin not properly checking if the ownid_shared_secret value is empty prior to authenticating a user via JWT. This makes it possible for unauthenticated attackers to log in as other users, including administrators, on instances where the plugin has not been fully configured yet.

The Tablesome Table – Contact Form DB – WPForms, CF7, Gravity, Forminator, Fluent plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the set_featured_image_from_external_url() function in all versions up to, and including, 1.1.32. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible in configurations where unauthenticated users have been provided with a method for adding featured images, and the workflow trigger is created.

CVE-2025-11833 is a missing-authorization flaw (CWE-862) in the Post SMTP WordPress plugin: in all versions up to and including 3.6.0, the email-log handling set up in the plugin's __construct function is registered without a capability check, so the log-viewing functionality effectively accepts requests from anyone. Any unauthenticated visitor who can reach the site can therefore read arbitrary emails logged by Post SMTP, including WordPress password-reset emails containing password reset links. By harvesting a reset link addressed to an administrator, an attacker can complete the password reset and take over the account, a full site-admin compromise reflected in the critical 9.8 CVSS score. Any WordPress site running Post SMTP 3.6.0 or earlier is affected, on the order of hundreds of thousands of installations. No public proof-of-concept, KEV listing, or confirmed in-the-wild exploitation is documented yet, but the EPSS of 51% (99th percentile) signals a high probability of exploitation within the next 30 days.

Do: Update the Post SMTP plugin to the latest release, since every version through 3.6.0 is vulnerable. Until patched, purge stored email logs, consider temporarily disabling the plugin or blocking its log endpoints with WAF rules, and review the log for password-reset emails sent to administrators; treat any admin account whose reset emails appear in the log as potentially compromised, rotate those credentials, and enable two-factor authentication.

A security vulnerability has been detected in Tenda AC23 16.03.07.52. Affected is the function saveParentControlInfo of the file /goform/saveParentControlInfo. Such manipulation of the argument Time leads to buffer overflow. It is possible to launch the attack remotely. The exploit has been disclosed publicly and may be used.

CVE-2025-55234 is an improper authentication flaw (CWE-287) in the Microsoft SMB Server that leaves systems susceptible to credential relay attacks when SMB signing and Extended Protection for Authentication (EPA) are not enforced. It is configuration-dependent: an attacker who can induce an authenticated SMB connection, for example by tricking a user or machine into connecting to attacker-controlled resources, can relay the credentials to another host and authenticate as that user. Successful relaying grants the attacker the privileges of the relayed user, up to elevation of privilege on target systems, with high impact on confidentiality, integrity and availability. Affected systems span Windows 10 (1507 through 22H2), Windows 11 (22H2 through 24H2), and Windows Server 2008, 2012, 2016 and 2019, although only environments without SMB signing/EPA hardening are practically exploitable. As of the September 2025 Patch Tuesday release there is no known in-the-wild exploitation or public proof of concept, but EPSS assigns a 20.1% probability of exploitation within the next 30 days (97th percentile).

Do: Install the September 2025 (or later) Microsoft security updates, which add SMB Server Hardening audit capabilities, and use the new audit events to identify clients, servers or legacy software that would break if SMB signing and EPA are enforced. After remediating incompatibilities, enable SMB Server signing and Extended Protection for Authentication on SMB servers to close the relay exposure, prioritizing domain controllers and file servers. Note that systems already enforcing both signing and EPA are not practically exposed.

CVE-2025-59230 is an improper access control flaw (CWE-284) in the Windows Remote Access Connection Manager service that allows an attacker who already has low-privileged access on a machine to gain elevated privileges locally. It is triggered by a local, authenticated user abusing the flawed access checks in the service; no remote or unauthenticated attack path is indicated by the CVSS vector (AV:L/PR:L). A successful exploit yields high impact to confidentiality, integrity and availability on the host, effectively giving the attacker full local control that can support persistence and lateral movement. All listed Windows 10 and Windows 11 releases and Windows Server 2008, 2012 and 2016 are affected. The flaw is being actively exploited: CISA added it to the Known Exploited Vulnerabilities catalog on 2025-10-14, coinciding with Microsoft's October 2025 Patch Tuesday (one of six actively exploited zero-days patched that day), though no public PoC is known and ransomware use is unknown.

Do: Apply Microsoft's October 2025 security updates for the affected Windows 10/11 and Windows Server releases immediately, prioritizing the per-version updates listed in Microsoft's advisory; as a CISA KEV entry (added 2025-10-14), BOD 22-01 remediation timelines apply for federal agencies. Because exploitation requires local code execution, prioritize hosts where low-privileged users can run code (RDS/VDI servers, kiosks, shared workstations) and verify that clients and servers have pulled the latest cumulative updates rather than relying on HEU state. There is no public PoC or documented mitigation, so patching is the primary defense.
