CVE-2024-47857
CriticalSummary
Wersje PrivX od 18.0 do 36.0 mają niewystarczającą walidację podpisów kluczy publicznych podczas korzystania z natywnych połączeń SSH przez port proxy. To umożliwia istniejącemu kontu PrivX 'konto A' podszywanie się pod inne istniejące konto PrivX 'konto B' i uzyskanie dostępu do hostów SSH, do których 'konto B' ma dostęp.
Risk Assessment
Organizacja narażona jest na ryzyko nieautoryzowanego dostępu do systemów, co może prowadzić do wycieku danych lub naruszenia integralności systemów. Atakujący może wykorzystać tę podatność do przejęcia kontroli nad zasobami, do których ma dostęp konto 'B'.
Recommendation
Zaleca się aktualizację do najnowszej wersji PrivX, która naprawia tę lukę. Dodatkowo, warto wprowadzić dodatkowe mechanizmy weryfikacji tożsamości użytkowników korzystających z połączeń SSH.

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.
- CVE-2026-82460Critical
Cloud Commander before version 19.20.2 contains a directory traversal vulnerability in REST file-operation and markdown endpoints that fails to properly validate path normalization. Attackers can use path traversal sequences to read, write, move, or copy files outside the configured root directory.
- CVE-2026-82456Critical
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.
Original NVD description (English source)
SSH Communication Security PrivX versions between 18.0-36.0 implement insufficient validation on public key signatures when using native SSH connections via a proxy port. This allows an existing PrivX "account A" to impersonate another existing PrivX "account B" and gain access to SSH target hosts to which the "account B" has access.
