CVE-2001-0061
HighSummary
In FreeBSD and possibly other operating systems, procfs does not properly restrict access to per-process mem and ctl files. This allows local users to gain root privileges by forking a child process and executing a privileged process from the child, while the parent retains access to the child's address space.
Risk Assessment
This vulnerability poses a risk that local users can gain unauthorized root privileges, potentially leading to serious security breaches in the system.
Recommendation
It is recommended to restrict access to mem and ctl files in procfs and to monitor and audit user activity to detect potential privilege escalation attempts.

A vulnerability was found in TOTOLINK NR1800X 9.1.0u.6681_B20230703 in the setUploadSetting function of /cgi-bin/cstecgi.cgi. Manipulation of the FileName argument leads to a stack-based buffer overflow. The attack can be executed remotely, and the exploit has been made public.
- CVE-2026-77956Critical
A code injection vulnerability in ash-project ash_ai allows a remote, unauthenticated client to execute arbitrary Elixir code. AshAi.Actions.Prompt evaluates prompt content through EEx.eval_string/2, and when prompt content incorporates request data, attacker-controlled text is compiled and run as an EEx template. This affects ash_ai from 0.1.0 before 1.0.0.

- CVE-2026-15980Critical
The MyHome Core plugin for WordPress up to version 4.4.5 contains an authentication bypass vulnerability. This is due to missing authorization in the send_link() AJAX handler and improper token validation in the activate() function. This allows unauthenticated attackers to generate an activation token for an unconfirmed user account and obtain a valid authentication cookie for that account, including administrators.
- CVE-2026-15369Critical
The Custom User Registration Fields for WooCommerce plugin for WordPress is vulnerable to Privilege Escalation in versions up to and including 2.2.3. This is due to the plugin accepting an attacker-controlled afreg_select_user_role value from the unauthenticated WooCommerce Store API /wc/store/v1/checkout request, persisting it in order meta, and then passing it directly to WP_User::add_role() without validating against the plugin's admin-configured allowed role list. This makes it possible for unauthenticated attackers to elevate their privileges to Administrator by creating an account during checkout with a modified JSON body specifying administrator as the desired role.

argocd-mcp 0.8.0 binds its HTTP transport to every network interface and accepts MCP sessions without requiring caller credentials when ARGOCD_API_TOKEN is configured. Attackers who can reach the listener can invoke the full tool surface using the operator's stored token to create applications, request syncs, and modify Argo CD resources.
